00:00In 1995, Tokyo was engulfed in terror.
00:07Get out! Get out!
00:09It's dangerous! There's gas coming out!
00:13In the middle of a rush to get to work,
00:1514 people died,
00:17and 6,300 injured.
00:20It was the third time.
00:22In the middle of a rush to get to work,
00:2514 people died,
00:27and 6,300 injured.
00:32The subway slalom incident.
00:34It was the worst crime in the history of Japan,
00:37which was carried out using chemical weapons.
00:42Initiation is the meaning of Higidenju.
00:48The perpetrator of the incident was
00:50the leader of the religious organization,
00:52Aum Shinrikyo,
00:54Matsumoto Chizuo, a.k.a. Masahara Shoko.
01:00On the other side of the century,
01:02there was a battle between
01:04the Special Investigation Team
01:06and the Special Investigation Team
01:08for 57 days.
01:13Keishicho Research Institute,
01:16also known as Kasoken.
01:20This is the story of
01:22the brain and courage
01:24that challenged the
01:27resolution of the terrible chemical terror.
01:49The galaxy in the sand
01:52where everyone sits
01:57Where did everyone go?
02:01Without being seen off
02:07Pegasus in the meadow
02:11Venus in the corner of the city
02:16Where did everyone go?
02:20Without being seen off
02:26No one remembers
02:28the stars on the ground
02:30People are just looking at the sky
02:36Hey rain,
02:38because it's a red sky
02:40Tell me
02:43the stars on the ground
02:46Tell me
02:48the stars on the ground
02:50Where are they now?
02:58New Project X Challengers
03:01Tonight, the story of
03:03the researchers who worked hard
03:05to solve the subway siren incident
03:07that remains a criminal history of Japan.
03:09We found new materials
03:11for this story.
03:13Here it is.
03:15This is a video recording
03:17the whole view of
03:19the giant chemical plant
03:21in Oumu, which has been surrounded
03:23by Beirut so far.
03:25And this is a number of
03:27detailed records of
03:29the process of
03:31conquering the country
03:33and planning to
03:35manufacture the deadly siren.
03:37The key to the investigation
03:39of the incident
03:41was the researchers
03:43of the Keishicho Research Institute,
03:45a.k.a. Kasouken.
03:47There was an untold story
03:49of people who had never
03:51been on the front lines.
03:56In 1981,
03:58a young man
04:00entered the research institute
04:02next to the Keishicho.
04:09Keizo Harafuji,
04:1123 years old.
04:13He wanted to contribute
04:15to society,
04:17so he changed jobs
04:19at a pharmaceutical company.
04:21There was a process
04:23of determining
04:25whether a criminal
04:27was guilty or not.
04:29When I heard that,
04:31I thought,
04:33this is it,
04:35the Kasouken of Akogere.
04:37He was the first scientist
04:39in the detection of
04:41gas and toxins.
04:43He jumped in,
04:45but he was surprised
04:47by the atmosphere
04:49of the workplace.
04:53The researchers
04:55were not motivated.
04:59There were many old equipment.
05:03It was said that
05:05it was a good idea
05:07to sell it to the private sector.
05:09There were some
05:11who were against it.
05:17He wanted to challenge
05:19a new approach.
05:21When Harafuji proposed it,
05:23he was told
05:25not to do unnecessary things.
05:27Harafuji,
05:29you know,
05:31there is a saying,
05:33when you join a company,
05:35everyone has the same question.
05:37After 3 or 5 years,
05:39you won't have any questions.
05:41Kasouken is a good job.
05:43It's great to
05:45work together
05:47and get along.
05:49But I thought,
05:51I didn't join Kasouken
05:53for this reason.
05:57The reason why
05:59he was not motivated
06:01was that
06:03he didn't trust
06:05the investigators.
06:09His junior,
06:11Oshita,
06:13regretted
06:15his absence.
06:19In the end,
06:21there were investigators
06:23who said that
06:25the king of evidence
06:27was self-evident.
06:29I wondered
06:31what would happen.
06:35Harafuji,
06:37who was full of energy,
06:39didn't want to be
06:41caught up
06:43in a long story.
06:45He was opposed by his superior,
06:47but he challenged
06:49the judge.
06:51He was fired from his job.
06:53He failed
06:55the promotion test twice.
06:57He was about to explode.
07:01I thought I was excellent.
07:03If they didn't
07:05accept me,
07:07I would quit the organization.
07:09I wanted to be
07:11recognized by the society
07:13and improve myself.
07:15I wanted to spin out
07:17and move to a better place.
07:21He decided to
07:23enter the university
07:25at the age of 35.
07:27He got a PhD
07:29from a research institute.
07:33He thought about
07:35quitting,
07:37but he wanted to
07:39be useful to society.
07:41So he took a test.
07:47Then,
07:49the incident happened.
07:51March 20th, 1995
07:53It was almost 8 a.m.
07:59Get out!
08:01It's dangerous!
08:03There's gas!
08:05On the Marunouchi Line,
08:07Hibiya Line,
08:09and Go-sharyo,
08:11a mysterious liquid
08:13was scattered.
08:17People with dizziness
08:19and difficulty in breathing
08:21were overflowing.
08:23It was a chaos.
08:29An hour later,
08:31a man with a plastic bag
08:33rushed to Kasoken.
08:37He asked for an emergency inspection.
08:41A second scientist
08:43from Harafuji
08:45told the machine
08:47and the result was surprising.
08:53Suddenly,
08:55I was shown as Salin.
08:57I panicked.
08:59I remember
09:01my mouth was very bitter.
09:05Salin is a
09:07neurotoxin
09:09developed by Nazi Germany
09:11as a chemical weapon.
09:13If you inhale a little,
09:15you will die.
09:17It was a deadly poison.
09:23I was shocked
09:25to find that
09:27such a person
09:29was in Japan.
09:31A countermeasure headquarters
09:33was set up
09:35in the police station.
09:39Shiro Hirohata,
09:41who became the deputy head of the headquarters,
09:43thought he was killed
09:45by the O.M.
09:47I was shocked,
09:49but I was shocked
09:51and thought
09:53I was killed
09:55by the O.M.
09:57I was not the only one
09:59who was shocked.
10:01All the people
10:03in the investigation team
10:05were shocked.
10:09Already,
10:11O.M. Shinrikyo
10:13was the target
10:15of the investigation.
10:21Among the investigators,
10:23it was suspected
10:25that the O.M.
10:27was producing poison.
10:35To get evidence,
10:37the police
10:39forcibly searched
10:41all the organizations
10:43in Japan.
10:45A large number of drugs
10:47were found,
10:49but they could not
10:51find the O.M.
10:57Asahara strongly
10:59denied
11:01the production of O.M.
11:03It was prepared
11:05for the purpose
11:07of arresting the O.M.
11:09Therefore,
11:11I cannot understand
11:13whether the O.M.
11:15was produced
11:17by these substances
11:19or not.
11:27In order to arrest the O.M.,
11:29it was necessary
11:31to expose
11:33the whole O.M.
11:37After four days,
11:39the O.M.
11:41was found
11:43in Harafuji.
11:47However,
11:49the O.M.
11:51did not expect
11:53the O.M.
11:55to be found in Harafuji.
11:57The O.M.
11:59was a trap.
12:01I am sorry
12:03that the O.M.
12:05was found
12:07in Harafuji.
12:09However,
12:11the O.M.
12:13did not want
12:15the O.M.
12:17to be found
12:19in Harafuji.
12:25Harafuji was
12:27instructed to do
12:29a simple job.
12:31However,
12:33the O.M.
12:35was found in Harafuji.
12:37I want you to
12:39read the O.M.
12:41that was found
12:43in Harafuji.
12:45I don't have
12:47a position
12:49to stay by his side
12:51and answer
12:53only what he asks.
12:55If that is the case,
12:57I will go back.
12:59I am a person
13:01who can explain
13:03the O.M.
13:07The O.M.
13:09had an unknown bundle of paper.
13:11When he looked through
13:13the eyes of Harafuji,
13:15he saw a powerful source of information.
13:19Various poisonous substances
13:21and chemical weapons
13:23have been experimented
13:25over a long period of time.
13:27The O.M.
13:29is a group
13:31of sophisticated scientists
13:33who surpass
13:35all expectations.
13:41When he reported to the police chief,
13:43the color of his eyes changed.
13:45All of them
13:47are important information.
13:49Please help me
13:51investigate more.
13:53Where are you going
13:55from tomorrow?
13:57I will let you go
13:59as you please.
14:01Instead,
14:03please come to me
14:05once a day
14:07and report
14:09what you did that day.
14:11Please report
14:13the same thing
14:15to the chief of the O.M.
14:17At the end of March,
14:19a scientific committee
14:21was set up
14:23to analyze the O.M.
14:25The O.M. was
14:27an experiment
14:29with a group of young people
14:31who have mastered
14:33the O.M.
14:35and the O.M.
14:37and are trying
14:39to advance
14:41their research.
14:43The O.M.
14:45is a great opportunity
14:47to show the world
14:49that science can
14:51protect the peace.
14:53I feel like I have to do it anyway.
14:59Science investigation will lead to the solution of the case.
15:05The days of unrest have begun.
15:13We have a guest.
15:14Mr. Keizo Harafuji, who was a member of the Science Investigation Research Institute,
15:19and Mr. Shiro Hirohata, who was in charge of the investigation as a former detective.
15:24Nice to meet you.
15:25Nice to meet you.
15:27Mr. Hirohata.
15:28You were accused of being killed by the O.R.M.
15:34The case happened on March 22,
15:39when the O.R.M. was preparing to search the base of the O.R.M.
15:44The O.R.M. people were the ones who came to their senses.
15:54First of all, what kind of position is the Science Investigation Research Institute in the department of detectives?
16:01The Science Investigation Research Institute is in the department of detectives,
16:06but it is not authorized to investigate, investigate, or arrest.
16:11In fact, the Science Investigation Research Institute is a place where no information about the situation of the investigation comes in at all.
16:18Even if it comes, it's the last place to come, so I couldn't draw the head of the O.R.M.
16:25I see.
16:26I don't know the situation of the investigation at all.
16:29It's not like we're fighting.
16:33It's a little distant from the detective world.
16:40I think it was a little distant from the friends who laughed together.
16:52There was a time when I thought I would quit the O.R.M.
16:57What was the biggest reason you stayed?
17:00Yes. I thought I could stay in a place like this for a while.
17:05So I went to college for a long time and took the O.R.M. for eight years.
17:11The professor said,
17:13Mr. Harayuji, don't you always want the O.R.M.?
17:19I said, yes, I want the O.R.M. as soon as possible.
17:27But he said, that's wrong.
17:32The O.R.M. is not for a goal or purpose.
17:36I have to do something for society until I die.
17:41At that time, I felt like I had a duty to take the O.R.M. and contribute to society.
17:50Now, detective Hirohata and scientist Harayuji,
17:54the tag team of the science team, will move in earnest for the arrest of Asahara.
18:02One week after the incident.
18:05There was still no sign of the arrest.
18:12There was no clear evidence to support the tag team's involvement.
18:21Seiji Yoshida, from Tokyo, who was aiming for the foundation of the O.R.M.
18:29Everyone says it's a crime of O.R.M.
18:32But the fact that Japanese citizens have the O.R.M. is not enough to prove it.
18:39We have to investigate the whole O.R.M. case.
18:44We have to investigate the whole O.R.M. case.
18:50How did the O.R.M. make saline in the chemical factory?
18:55The science team was asked to collect evidence that could not be ignored.
19:03Hundreds of cardboard boxes were filled with documents of the believers, such as experimental notes.
19:14In the meantime, Ota, who was analyzing the documents, came across powerful information.
19:23This is a copy of the 12 floppy disks that were collected from the control room of the 7th Sation.
19:38This document was recorded as a block diagram.
19:44The flow of the chemicals was recorded as a system.
19:52The substance name of the final ingredient was hidden by an asterisk.
19:57But scientifically, it was definitely saline.
20:03I don't know if this really happened.
20:08I think I found the most important thing.
20:14Harafuji analyzed the flow and reaction of the chemicals in detail.
20:20He came up with an idea to prove the production of saline.
20:29The substance that was not recorded in the diagram could be a proof of a partial decomposition.
20:38When saline, a delicate chemical substance, touches heat or air, it immediately decomposes.
20:48At that time, a special substance is generated.
20:52Methylpropionic monosulfate propyl, commonly known as monosulfate.
20:58If saline was produced, this monosulfate should be found.
21:07If monosulfate came out of the final reaction diagram, saline was produced.
21:12In other words, this is a proof that saline was produced.
21:17When the head of the investigation, Terao, reported this, words came back to him.
21:23Mr. Hara, would you like to go to Kamikura?
21:30It is customary for inspectors to collect evidence at the site.
21:35The researcher's dispatch was a special case.
21:41I thought I had to find something with this hand.
21:47I thought I had to find something with this hand.
21:54In such a big case, I was pulled to the center.
22:00I had to do my best to respond to the weight of responsibility and trust that I was given in my social life.
22:14On April 3rd, Harafuji entered Kamikuri Shikimura, the 7th Satian.
22:27The inside was filled with huge devices, like a maze.
22:34However, the more I rubbed, the more it was worth looking at the design diagram.
22:40I realized that I could get the manufacturing process.
22:49As I followed the devices, I found a narrow staircase.
22:54The kiln ahead of it was the final step.
23:02When I went down this staircase, I was really nervous.
23:07I was worried that there might still be remnants of Satian inside.
23:13I was worried that there might still be remnants of Satian inside.
23:20I was worried that there might still be remnants of Satian inside.
23:24I was worried that there might still be remnants of Satian inside.
23:33Harafuji was convinced.
23:36There must be a temporary decomposing object near the kiln that completed the Satian.
23:45He took the remains of Satian inside the kiln.
23:49He took the remains of Satian inside the kiln.
23:52He thoroughly investigated the surrounding laboratory.
24:03The next day, a temporary decomposing object, Monoiso, was found in the equipment of the laboratory.
24:15The final step of the process showed that the object was very close to the kiln.
24:22I was convinced that the object was close to the kiln.
24:27I was convinced that the object was close to the kiln.
24:33There was no doubt that Ohm was making Satian.
24:37The scientific team set out to work on the proof.
24:44Ohshita, a pharmacist, was in charge of analyzing and organizing the obtained drugs.
24:55There is no point in keeping things that can only be found by oneself.
25:07Ohta, a physicist, analyzed the structure of the chemical factory.
25:13He analyzed each of the thousands of pipes in order.
25:27The scientific team looked at the results and began to ask questions.
25:38I wanted to know what people didn't know.
25:41I wanted to know what people didn't know.
25:45I wanted to know what people didn't know.
25:54The report on page 40 of the Harafuji's report
25:59contained all the details of the production of Satian.
26:06I think the report was very valuable.
26:12The inspectors, including me,
26:15who were involved in the saline plant incident
26:19put the contents of the report in their heads
26:23and determined the direction of the case.
26:28One month after the incident, the evidence was gathered.
26:36The inspectors from Hirohada
26:39were busy asking questions to the believers
26:42and preparing for the execution.
26:47Finally, there was something necessary for the arrest of Asahara.
26:53Who was the person who was making the saline?
26:56And was it an organizational tool?
27:05The most important person in the investigation
27:09was Asahara's close associate,
27:11and the person in charge of the scientific team, Masami Tsuchiya.
27:16Masami Tsuchiya
27:22However, the investigation was difficult.
27:26For two days after the incident began,
27:29he was completely unrecognizable.
27:37Harafuji was called out of the temple again and asked,
27:42Can you talk to Tsuchiya?
27:46He hoped that Harafuji's knowledge of science
27:49might be the trigger for the destruction of the tomb.
27:57Norio Horikawa, who was in charge of the investigation,
28:01was surprised by the unusual situation.
28:05It was a great honor for me
28:08to be able to talk to the inspectors
28:12who had been watching over me.
28:20But Harafuji, who had done more than he had expected,
28:25thought he could trust him.
28:28Norio Horikawa, who was in charge of the investigation,
28:31was surprised by the unusual situation.
28:34I'm sure the inspectors at the site
28:37knew what Harafuji was thinking.
28:41I'm sure they trusted him.
28:47In the end, the police suspected Harafuji.
28:51Harafuji was executed on the spot.
28:57Project X.
29:01You went inside the 7th Satyan
29:04and saw the entire science of the tomb.
29:10The piping and the reactor
29:14are very well-connected.
29:18It's very well-made.
29:21The Aum Shinrikyo
29:24and the pipes are all hand-made.
29:28I was very surprised
29:31that an amateur could make something like this.
29:34Did you find it right away?
29:36There was a research tower
29:39used by Masami Tsuchiya and Seiichi Endo.
29:42I went in there.
29:45When I was looking for it,
29:48there was a hidden door like a secret room.
29:51It was like a science lab.
29:54I knew I would find the Aum Shinrikyo.
29:57I knew I would find the Aum Shinrikyo.
30:00As a result, I found the Aum Shinrikyo.
30:03At that moment, I thought,
30:06I did it.
30:08It was very moving.
30:11The fact that you found the Aum Shinrikyo
30:14was a big step forward
30:17for you and Masami Tsuchiya.
30:21In that process,
30:24you met Masami Tsuchiya.
30:27Did you have a goal in mind?
30:33I didn't have a goal.
30:36I didn't know what would happen,
30:39but I wanted to meet him.
30:42I wanted to do what I could.
30:45That's how I met him.
30:50Six hours before meeting Tsuchiya,
30:55Harafuji read the final paper
30:58Tsuchiya wrote when he was a graduate student.
31:05It was about organic synthesis
31:08by chemical reactions.
31:12He was a serious and excellent researcher.
31:21I met the Aum Shinrikyo,
31:24and I thought,
31:29this is where I belong.
31:34At 6 p.m.,
31:38Tsuchiya and the detective
31:41entered the interrogation room.
31:47Tsuchiya closed his eyes
31:50and sat down as if he were meditating.
31:58Tsuchiya didn't budge
32:01no matter how many times
32:04Harafuji looked at Tsuchiya.
32:10Fifteen minutes later,
32:13Harafuji asked the detective
32:16to leave Tsuchiya and Harafuji alone.
32:21I was completely rejected.
32:24I didn't know what to say.
32:28I told Tsuchiya,
32:31and Harafuji, as a scientist,
32:34decided to talk to Tsuchiya.
32:38He tried to talk to Tsuchiya.
32:43I read the paper.
32:46You seem to be a good scientist.
32:51Tsuchiya opened his mouth for the first time.
32:54He couldn't see the future
32:57at the university.
33:02He said one more thing.
33:06How was Aum?
33:10His face brightened.
33:13He said,
33:16Aum was the best.
33:19He gave me a lot of money.
33:22He gave me a lot of money.
33:27When Tsuchiya started to talk,
33:30the recorder came in.
33:33Tsuchiya stopped talking again.
33:46The long silence continued.
33:52Harafuji took the paper and the pencil.
33:59I had a white sheet of paper.
34:02I put it on the desk.
34:05I wrote the Sarin poem.
34:08I wrote the Sarin poem.
34:11I wrote the Sarin poem.
34:14I wrote the Sarin poem.
34:17Tsuchiya and I
34:20only had contact through the Sarin reactor.
34:23Tsuchiya and I only had contact through the Sarin reactor.
34:26Tsuchiya and I only had contact through the Sarin reactor.
34:29I thought I might not be able to talk,
34:32but I thought I would be able to
34:35communicate with him as a scientist.
34:40How to make Aum's Sarin.
34:43How to make Aum's Sarin.
34:46How to make Aum's Sarin.
34:49How to make Aum's Sarin.
34:52I kept writing.
35:00Two hours passed, but there was no reaction.
35:03Two hours passed, but there was no reaction.
35:06Then a scientific formula came to my mind.
35:09Then a scientific formula came to my mind.
35:13It was an impressive formula
35:16written on Tsuchiya's subordinate's notebook.
35:21It was a rare ingredient
35:24that was used in adhesives
35:27to make Sarin.
35:30to make Sarin.
35:34I read more than 100 Sarin-related papers.
35:37I read more than 100 Sarin-related papers.
35:40I couldn't find a synthetic method
35:43to make Sarin.
35:46It was a very unique thing
35:49that didn't exist in the world.
35:52I thought it was a reaction formula
35:55that Tsuchiya was the only one thinking of.
35:58I thought it was a reaction formula
36:01that Tsuchiya was the only one thinking of.
36:04I thought it was a reaction formula
36:07that was a very unique thing.
36:10I watched the video
36:13and closed my eyes.
36:16and closed my eyes.
36:19I watched the video
36:22and closed my eyes.
36:25I kept watching it.
36:28I was shivering.
36:31I was shivering.
36:34I wondered why he knew about it.
36:43Six hours after meeting Tsuchiya, Tsuchiya's heart was clearly shaking.
36:55Tsuchiya committed suicide.
36:58A few days later, he received a call from the head of the investigation team at the temple.
37:07Tsuchiya was writing down the details of the experiment with his own hands.
37:14On May 16, the investigation team finally arrested Kyoso Asahara.
37:45Harafuji felt empty after learning about the Wakitatsu detectives.
37:54He took a different path and went into the darkness.
38:01But I felt that before he went into the darkness,
38:06he didn't have a chance to contribute to society.
38:16At the end of October, the day came for the investigation team to return to Kasoken.
38:25It was time for the members to pack their bags and leave.
38:31The investigators gathered one after another, and a loud voice echoed throughout the room.
38:40Salute!
38:42More than 50 investigators lowered their heads and sent them out.
38:50I felt like I was recognized for what I had done.
38:56I don't know if I should say that I was happy.
39:04But I was a little moved.
39:09He was the greatest of the three.
39:20Do you remember when you left the headquarters?
39:23Yes, I do.
39:25The chief detective told me,
39:28Harafuji, you can go back to your normal duties from tomorrow.
39:35At the end, I said,
39:38Thank you for using me, and lowered my head.
39:43At the same time, I couldn't stop crying.
39:48How did you feel when you left?
39:51For me, it was a sense of accomplishment that the Oumu case went well.
40:03I was able to work because of that.
40:07And I was lonely.
40:11I think I had a sense of fulfillment in my life,
40:15because I was able to do my best.
40:19I think that's what I felt when I left.
40:25It was a complicated feeling.
40:29It's a six-hour face-to-face with Tsuchiya.
40:34As a veteran detective, what do you think happened?
40:41It's just a guess.
40:43I don't know, but I think Tsuchiya had something to say to himself.
40:52I'm not saying I agree,
40:55but I think there were other people who understood the pride of loneliness and pride.
41:05Can I ask you one last question?
41:07What kind of existence do you want the power of science to be?
41:11As a theorist, I often use the words,
41:15science does not lie and science is not plural.
41:21Science has no will by itself,
41:25so it can be used for both good and bad by those who use it.
41:30So how do you control it?
41:33That's what people are asking.
41:35So you have to have an eye for the truth,
41:39and you have to look at the whole picture in a more subjective way,
41:43and you have to understand what this position is,
41:46and you have to use it.
41:50The year after the incident,
41:53the Metropolitan Police Department established a new role as a science investigator,
41:58and was given the same investigative power as the police.
42:05The first science investigator was Mr. Harafuji.
42:11He was involved in many difficult cases.
42:17Lucy Blackman, who was kidnapped and killed by an English woman,
42:21was involved in the disappearance of Mr. Harafuji.
42:25Mr. Harafuji identified the drugs used,
42:30and contributed to the arrest of the culprit.
42:36Even now, at the age of 67,
42:39he continues to work as the Chief Inspector,
42:42cooperating with the public to develop science investigation technology.
42:51Mr. Oshita, who also became a science investigator,
42:56has transferred to the medical field
42:59and is supported by drug addicts.
43:0630 years after the incident,
43:09the Science Investigation Research Institute
43:12now employs more than twice as many people as it did at the time.
43:18Technology has evolved significantly,
43:21and the traces of drugs used
43:24can be traced back more than a year.
43:28The amount of drugs contained during the outbreak
43:32is now displayed in white,
43:35and the history of drug use can be seen.
43:38By producing a lot of such results,
43:41I think it will be the ultimate force against the case.
43:473D printer technology that can preserve the condition of the destroyed building for a long time.
43:53The use of 3D printer technology for investigation was Mr. Oshita's first plan.
44:07In July 2018,
44:10the execution of Asahara and Tsuchiya was carried out.
44:24The organization that honors Asahara as a hero
44:29is still active.
44:33The next project is a skateboard that was once called a hindrance to the city.
44:38It follows the youth of those who spread freedom and fun.
45:023D printer technology that can preserve the condition of the destroyed building for a long time.
