00:00In 1995, Tokyo was engulfed in terror.
00:07Get out, get out!
00:09It's dangerous, there's gas coming out!
00:12In the middle of a commuter train crash,
00:1514 people died,
00:18and 6,300 injured.
00:21It was the third time.
00:23The subway slalom incident.
00:25It was the worst crime in the history of Japan,
00:28using chemical weapons.
00:32Initiation is the meaning of Higidenjyu.
00:38The main perpetrator of the incident was
00:41the leader of the religious organization, Aum Shinrikyo.
00:44Aum Shinrikyo was the leader of the organization.
00:47Aum Shinrikyo was the leader of the organization.
00:50Asahara Shoko, also known as Matsumoto Chizuo,
00:53was the leader of the religious organization, Aum Shinrikyo.
00:56was the leader of the religious organization, Aum Shinrikyo.
00:59On the other side of the capture,
01:02there was a special investigation team
01:05that fought for 57 days.
01:12Police Department, Research Institute for Scientific Investigation.
01:16This is the so-called virtual sword.
01:22This is the story of intelligence and courage
01:25that challenged the revelation of the terrible scientific terror.
01:28that challenged the revelation of the terrible scientific terror.
01:47Sitting in the wind,
01:52the galaxy in the sand.
01:57Where did everyone go?
02:01Without being seen off.
02:07The eyes of the grassland point.
02:11The Venus of the street corner.
02:16Where did everyone go?
02:20Without being seen off.
02:26No one remembers the stars on the ground.
02:30People are just looking at the sky.
02:36Hey, eyes.
02:38Tell me from the red sky.
02:43Let's look at the stars on the ground.
02:48Where are the stars on the ground now?
02:58New Project X Challengers.
03:01Tonight, it is the story of the researchers
03:04who worked hard to solve the subway siren incident
03:07that remains a criminal history of Japan.
03:10We found new materials in this interview.
03:13Here it is.
03:15This is a video recording the whole view
03:18of the giant chemical plant in Oumu,
03:21which has been surrounded by a veil so far.
03:24And these are a number of materials
03:27that record in detail the process of
03:30capturing the national skydome and
03:33plotting to manufacture the deadly siren.
03:36The key to the investigation is chemical investigation.
03:40The researchers at Keishicho Chemical Investigation Laboratory,
03:44also known as Kasouken, are at the center of the investigation.
03:48There is an untold story of the people
03:51who have never been on the front lines.
03:56In 1981, a young man entered Keishicho Chemical Investigation Laboratory.
04:07Keizo Harafuji, 23 years old.
04:10He wanted to contribute to society,
04:13so he changed jobs at a pharmaceutical company.
04:19There is a process of determining
04:22whether a criminal is guilty or not.
04:25When I heard that, I thought,
04:28this is it, the Kasouken I admire.
04:31I felt like my heart was beating.
04:36He was the first scientist to study gas and toxins.
04:44He jumped in with enthusiasm,
04:47but was surprised by the atmosphere of the workplace.
04:53The researchers were not motivated.
04:58There were a lot of old equipment.
05:02There was also a senior who said,
05:05if it's a difficult case,
05:08we should send it to the private sector.
05:16I want to challenge a new case.
05:19When Harafuji proposed it,
05:22I was told not to do anything unnecessary.
05:27Harafuji said,
05:29there is a saying,
05:31leave it to the long term.
05:33If you come in,
05:35everyone will have the same question.
05:38After 3 or 5 years,
05:40you won't think of anything.
05:42Kasouken is a good workplace.
05:44It's great to spend time with everyone
05:47in a warm place.
05:49But I thought,
05:51I didn't come to Kasouken for this.
05:57The reason why he wasn't motivated,
06:00he soon realized.
06:03The detectives who were in charge of the investigation
06:07had low expectations of him.
06:10His junior, Oshita,
06:12lamented the lack of presence.
06:18In the end,
06:22there were investigators who said
06:25it was a waste of time.
06:27So I thought,
06:29what about the results?
06:34Harafuji, who was full of vigor,
06:37didn't intend to be left to the long term.
06:40He was opposed by his superior,
06:43but he challenged the detectives.
06:49He was fired from his job.
06:52He failed the probation test twice.
06:56His dissatisfaction was about to explode.
07:01If they don't acknowledge that I'm good,
07:06I'll quit this organization.
07:09I want to be recognized by society,
07:12I want to improve my skills,
07:14and I want to spin out.
07:16I want to move to a better place.
07:20As part of his duty,
07:22he decided to go to university.
07:25At the age of 35,
07:27he obtained a bachelor's degree in biology.
07:33He thought about quitting,
07:36but he wanted to be useful to society.
07:40So he took the probation test.
07:43And then,
07:45the incident happened.
07:51March 20th, 1995.
07:54It was just after 8 a.m.
07:57Get out!
07:59It's dangerous!
08:01There's gas coming out!
08:03On the train to Marunouchi and Hibiya,
08:06there was a strange liquid
08:09on the five-car train.
08:12The train was in a state of panic.
08:17People complained of dizziness and difficulty in breathing.
08:22It was a chaos.
08:29An hour later,
08:31a man with a plastic bag
08:33rushed to Kasoken.
08:37He asked for an emergency diagnosis.
08:40A second scientist from Harafuji
08:43took him to the machine,
08:46and he was surprised.
08:52I was suddenly shown a saline solution,
08:56and I panicked.
08:58I remember my mouth feeling very bitter.
09:06Saline was a chemical
09:09developed by Nazi Germany.
09:12It was a neurotoxin.
09:14If you inhaled even a little,
09:17you would die.
09:23I was shocked to find
09:26that there were people in Japan
09:28who thought of such a thing.
09:31A countermeasure headquarters was set up
09:34at the police station.
09:38Shiro Hirohata,
09:40who became the deputy head of the headquarters,
09:43thought he had been attacked by the O-MU.
09:47I panicked and panicked.
09:50I thought,
09:52oh no, I was attacked by the O-MU.
09:55I was not the only one.
09:58I could feel the face of the head of the O-MU
10:01standing next to me,
10:04and he whispered to me.
10:09Shinrikyo O-MU,
10:12who had already been suspected of
10:15being a target of Nazi Germany's attack.
10:20Among the head of the O-MU,
10:23it was suspected that
10:26he was a member of the O-MU.
10:34To gather evidence,
10:37the police forcibly searched
10:40the Nazi headquarters
10:43with about 2,500 people.
10:46A large number of drugs were found,
10:49but they were unable to find
10:52the cause of the attack.
10:57Asahara strongly denied
11:00the production of saline.
11:03It was a drug that was used
11:06to produce drugs and fertilizers.
11:09As a result,
11:12I did not believe
11:15that saline was produced
11:18or produced
11:21by Nazi Germany.
11:27In order to arrest him,
11:30he had to reveal the whole story
11:33of the O-MU scientific experiment.
11:39He called someone who was familiar with drugs.
11:42Four days after the incident,
11:45a white-leaf arrow was fired at Harafuji.
11:49However, the head of the O-MU
11:52did not expect anything from Harafuji.
11:55It was a trap.
12:00I am sorry that I treated him like a trap.
12:03If he had stayed by my side,
12:06I could have asked him
12:09what was going on
12:12when he said,
12:15I want an expert
12:18who can explain it
12:21like an amateur.
12:25Harafuji was instructed to do a simple job.
12:28However, the head of the O-MU
12:31vowed that he did not want it to end.
12:37I want him to read
12:40a large amount of Oshu documents
12:43and explain it to me.
12:46I do not have the stance
12:49to stay by his side
12:52and answer only what he asks.
12:55If that is the case,
12:58I will go home.
13:01I am a man who has studied
13:04the toxicity of gas.
13:07I am the one who can explain it.
13:10When the head of the O-MU
13:13looked through the eyes of Harafuji,
13:16it became a powerful source of information.
13:19The traces of his experiments
13:22with various toxins and chemical weapons
13:25over a long period of time
13:28came out one after another.
13:33It was a high-level group of scientists
13:36that exceeded expectations.
13:41When Harafuji reported to the head of the O-MU,
13:44his eyes changed color.
13:47All of it was important information.
13:50Please help me investigate more.
13:54I will tell you where to go
13:57and what to see from tomorrow.
14:00You can do whatever you want.
14:03Instead, come to me once a day
14:06and tell me what you did that day.
14:09Tell the head of the O-MU the same thing.
14:17At the end of March,
14:20a scientific committee was set up
14:23to analyze the O-MU.
14:29Oshita, who was an expert in drugs.
14:33Ota, a physicist.
14:36A group of young people
14:39who wanted to advance in scientific investigation.
14:43It was a great opportunity
14:46to prove that we can protect the peace
14:49with the eyes of science.
14:52I felt like I had to do it.
14:58Ota led the investigation
15:01to solve the case.
15:05The days of chaos began.
15:13We have a guest.
15:15Harafuji Keizo,
15:17a member of the Science Investigation Institute,
15:20and Shiro Hirohata,
15:23a former detective.
15:26Nice to meet you.
15:28Mr. Hirohata.
15:30The O-MU was set up
15:33to investigate the O-MU base
15:36on the 20th of March.
15:39The O-MU members were the ones
15:42who came up with the idea.
15:45The O-MU members were the ones
15:48who came up with the idea.
15:51The O-MU members were the ones
15:54who came up with the idea.
15:57Let's take a look
16:00at the position of the Institute.
16:03The Institute is located
16:06in the police department,
16:09but it is not authorized
16:12to investigate or arrest people.
16:15The Institute is not authorized
16:18to investigate or arrest people.
16:21It is the last place
16:24to investigate.
16:27We didn't know the situation.
16:30We didn't know the situation.
16:33We are not fighting.
16:36The Institute is a bit distant
16:39from the detective world.
16:42I think the Institute is a bit distant
16:45from the detective world.
16:48I think the Institute is a bit distant
16:51There was a time when I thought I would quit the costume industry.
16:57What was the biggest reason you stopped?
17:00I was really depressed at the time.
17:02I didn't know if I could stay in a place like this.
17:05So I went to university and took classes for 8 years.
17:10The professor said,
17:12Harayuji-kun, don't you always want to take classes?
17:19I told him that I wanted to go back to school.
17:23He said, that's right. I want to go back to school as soon as possible.
17:27I told him, but he said, that's wrong.
17:32He said, school is not a goal.
17:36I have to do something for society until I die.
17:41At that time, I felt that I had a duty to take classes and contribute to society.
17:50Now, Hirohata-san and Keiji-san and Harayuji-san.
17:54The science team's tag team is moving in earnest towards the Asahara arrest.
18:02One week after the incident.
18:05There was still no sign of the arrest.
18:12There is no clear evidence to support the association.
18:21Seiji Yoshida of the Tokyo branch of the Asahara Association.
18:29Everyone says it's a crime against the government.
18:33I don't think it's enough to just say that the Japanese people have it.
18:39We need to investigate the whole case of the O-bun case.
18:50How did they make saline at the chemical plant?
18:55The science team sought evidence that could not be ignored.
19:03Hundreds of cardboard boxes were filled with testimonies of believers and experimental notes.
19:09They were read from one end to the other.
19:14In the midst of this, Ota, who was analyzing the materials, came across powerful information.
19:23This is from the 7th Satyan control room.
19:29This is one of the 12 floppy disks that were collected from the 7th Satyan control room.
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.
19:58There was no doubt that it was saline.
20:03It was as if something like this had finally happened.
20:08It was as if we had found the most important thing.
20:16Harafuji analyzed the flow and reaction of the chemicals in detail.
20:22He came up with an idea to prove the production of saline.
20:30The substance that was not recorded in the diagram.
20:34Could it be evidence of a temporary decomposition?
20:40Saline, a delicate chemical substance,
20:44immediately decomposes when it touches heat or air.
20:49At that time, a special substance is produced.
20:54It is called a methylpropyl monoisopropyl.
21:02If saline was produced, this monoisopropyl should be found.
21:11If monoisopropyl comes out of the final reaction, saline is produced.
21:15In other words, it is proof that this was produced.
21:20When he reported to the head of the investigation team,
21:24he said something unexpected.
21:28Mr. Hara, could you go to Kamiku?
21:36It is customary for the inspection to collect evidence at the site.
21:41The researcher's dispatch was unusual.
21:47I thought I had to find monoisopropyl with my own hands.
21:54In such a big case,
21:57I was pulled to the center.
22:00In my social life,
22:02I have to do my best to respond to the weight of responsibility
22:06and the feeling of being trusted.
22:14On April 3rd,
22:17Mr. Hara entered Kamiku Ishikimura's 7th Satian.
22:27Inside, he was filled with a huge device,
22:31and he entered like a maze.
22:36Kamiku Ishikimura
22:42However, the more he rubbed, the more it was worth seeing the design.
22:48He understood how to make it.
22:56Following the device, he found a narrow staircase.
23:06The kiln ahead of it was the final step.
23:14I was really nervous when I went down this staircase.
23:19I felt bad because there may still be a remnant of Saturn inside.
23:26Rather than being scared, I felt bad.
23:31Mr. Hara was convinced.
23:34There should be a monoisopropyl near the kiln where Saturn was completed.
23:46He took the adhesive that had accumulated inside the kiln
23:50and investigated the laboratory nearby.
23:55The next day, a monoisopropyl was detected
23:59from a device in the laboratory next to the one Mr. Hara was aiming for.
24:07The final step of the kiln also produced a material that was extremely close.
24:14I thought, oh, it's out.
24:17I thought, oh, it's out.
24:22I thought, oh, it's out.
24:24I thought, oh, it's out.
24:27I thought, oh, it's out.
24:33There was no doubt that Ohm was making Saturn.
24:37He set out to work on the proof.
24:43Ohm, a pharmaceutical specialist,
24:46was in charge of analyzing and organizing information
24:50about the obtained drugs.
25:06Ohm, a physicist,
25:08was in charge of analyzing the structure of the chemical plant.
25:14He analyzed the use of each of the thousands of pipes
25:18and the order in which the drugs were synthesized.
25:28He looked at the scientific team
25:31and the detectives began to ask him questions.
25:38They came to ask me questions that I didn't know.
25:41I didn't just want to be there.
25:45I wanted to answer their questions
25:48because they recognized my existence.
25:54In the 40-page report that Mr. Hara created,
25:59all of the Saturn production was described in detail.
26:06I think the report was very valuable.
26:12The detectives involved in the Saturn plant incident, including myself,
26:19put the contents of the report in their heads
26:23and decided on the direction of the proof.
26:30One month after the incident,
26:32the evidence was gathered.
26:37The detectives from Hirohata
26:39were busy asking questions to the believers
26:42and preparing for the execution.
26:48Finally, there was something necessary for the arrest of Asahara.
26:54Who was the person who was making the Saturn?
26:57And whether it was an organization or not.
27:05The person who was the most important person in the investigation
27:09was Asahara's close associate,
27:11and the person in charge of the scientific team,
27:14Masami Tsuchiya.
27:22However, the investigation was difficult.
27:26Two days after the incident,
27:28Asahara's secret was completely exposed.
27:36Harafuji was called out of the temple again and asked,
27:42Can you talk to Tsuchiya?
27:46Harafuji's knowledge of science
27:48may be the trigger for the secret to be revealed.
27:51This was what he hoped for.
27:57Norio Horikawa, who was in charge of the investigation,
28:01was surprised by the situation in the temple.
28:05It was the temple's job
28:08to talk to the witnesses
28:12who had witnessed the incident.
28:20But Harafuji, who had done more than expected,
28:25believed that he could entrust the secret to Tsuchiya.
28:32I think the people at the site saw Harafuji's determination.
28:41I think they trusted him.
28:47The final stage of the police's suspicion.
28:52Harafuji stood in the middle of the battle.
29:02He went inside the 7th Satyan
29:05and witnessed the entire science of Oumu.
29:10The piping and the reactor
29:14were very well-organized.
29:18I was very surprised
29:20that an amateur could make such a thing.
29:25Did you find it right away?
29:27There was a research tower
29:30used by Tsuchiya Masami and Endo Seichi.
29:33I went in there.
29:36When I was looking for it,
29:39I found a pipe.
29:42I thought,
29:44If I look for it,
29:47there is a door that opens like a hidden room.
29:50There is a science lab in the back.
29:54I thought,
29:56I will definitely find the monoiso.
30:00Did you find the monoiso?
30:03I thought,
30:05I did it.
30:08I was impressed.
30:11The fact that you found the monoiso
30:14was a big step forward for you.
30:22In the process,
30:24you met Tsuchiya Masami.
30:30Did you have a goal?
30:33I didn't have a goal.
30:35I didn't know what would happen,
30:38but I wanted to meet him.
30:40I wanted to do what I could do.
30:44That's how I met him.
30:50Six hours before meeting Tsuchiya,
30:55Harafuji read the final paper
30:59Tsuchiya wrote during his university days.
31:04The paper was about organic synthesis
31:07by chemical reactions.
31:11I thought he was a serious and excellent researcher.
31:20I met Tom Shinkyo
31:23and I thought this was where I should be.
31:34At 6 p.m.,
31:38Tsuchiya entered the lab with the detective.
31:47Tsuchiya closed his eyes and sat down,
31:51as if he were meditating.
31:55Despite Tsuchiya's insistence,
31:59Tsuchiya didn't budge.
32:07Fifteen minutes later,
32:09Harafuji asked the detective,
32:13if he could do it just the two of them.
32:18I was completely rejected.
32:21I was completely rejected.
32:24I didn't know what to say.
32:28I wanted to talk to Tsuchiya as a scientist,
32:32and Harafuji as a scientist.
32:38I tried talking to him.
32:42I read the paper.
32:44You were a good scientist.
32:49Tsuchiya opened his mouth for the first time.
32:58He was at a loss.
33:01He couldn't see the future.
33:06He tried to talk to him again.
33:09How was the research?
33:12How was the research?
33:15His face brightened up.
33:18He said,
33:20the research was great.
33:23He gave me a lot of money.
33:28Tsuchiya started talking,
33:31and the detective came in.
33:34Tsuchiya stopped talking again.
33:43The long silence continued.
33:56Harafuji took the paper and the pencil.
34:03I had a white piece of paper,
34:06and I put it on the desk.
34:09I started writing down the Sarin synthesis formulas,
34:13the five processes and the synthesis formulas,
34:16one by one, in silence.
34:21I thought Tsuchiya and I only had contact
34:24with the Sarin reaction formula.
34:28He may not be able to speak,
34:31but I thought he would be able to communicate
34:34with me as a scientist.
34:39How to make the Sarin formula,
34:42how to experiment,
34:45and how to describe the tools.
34:51I kept writing.
35:00Even after two hours,
35:02there was no reaction.
35:05At that moment,
35:08a chemical formula came to mind.
35:13It was an impressive formula
35:16written on Tsuchiya's notebook.
35:22It was a rare thing to make Sarin
35:25using the raw materials used
35:28in adhesives called silica gel.
35:31I read over 100 Sarin-related papers,
35:34but I couldn't find a synthesis formula
35:37that uses silica gel.
35:40It's a very unique formula
35:43that doesn't exist in the world.
35:46I thought it was a reaction formula
35:49that only Tsuchiya could think of.
35:52I wanted to write this down
35:55and show Tsuchiya.
35:59It was when I finished writing
36:02the reaction formula.
36:07I started to look around me
36:10and looked around me.
36:13I looked up at the sky and closed my eyes.
36:16I started to shake my body
36:19back and forth.
36:22I kept doing that
36:25for a long time.
36:28When I looked closely,
36:31I could see that I was shaking.
36:34I was wondering
36:37why I knew that.
36:43Six hours after meeting Tsuchiya,
36:46his heart was clearly shaking.
36:55Tsuchiya gave a lecture.
36:58A few days later,
37:01he received a phone call from
37:04the head of the investigation team.
37:07Tsuchiya was writing down
37:10the details of the experiment
37:13with his own hands.
37:17On May 16,
37:20the investigation team
37:23finally arrested
37:26Professor Asahara.
37:31The investigation team
37:34was forced to leave
37:37Wakitatsu University
37:40and head to Tokyo.
37:44Knowing the Wakitatsu detectives,
37:47Harafuji felt
37:50empty.
37:54He took a different path
37:57and went into the darkness.
38:00But somehow,
38:03someone understood him
38:06and gave him a chance
38:09to contribute to society.
38:12That's what I felt.
38:16At the end of October,
38:19the investigation team
38:22returned to Kaso Prefecture.
38:25It was time for the team
38:28to pack up and leave.
38:31The investigators came one after another
38:34and there was a loud voice
38:37in the room.
38:40Order!
38:42More than 50 investigators
38:45lowered their heads
38:48and sent him away.
38:51I felt like I was recognized
38:54for what I had done.
38:57It's hard to say
38:59that I was happy.
39:05I was a little moved.
39:10He was a great help
39:13to the investigators
39:16and their colleagues.
39:21Do you remember
39:23when you left the headquarters?
39:26Yes, I do.
39:28The chief detective told me
39:31that I could go back to work
39:34from tomorrow.
39:38I thanked him for using me
39:41and lowered my head.
39:44At the same time,
39:47I couldn't stop crying.
39:50What made you cry?
39:53For me,
39:56it was a sense of accomplishment
39:59that the Rome case went well
40:02and that I was able to work
40:05as a detective.
40:08But I also felt lonely.
40:11I had a sense of fulfillment
40:14that I was able to do my best
40:17in my life.
40:20It was a feeling
40:23that disappeared.
40:26It was a complicated feeling.
40:29You met Tsuchiya
40:33as a veteran detective.
40:36What do you think happened?
40:39It's just a guess,
40:42but I think Tsuchiya
40:45had something to say
40:48in his heart.
40:51I don't think he agreed with me.
40:54He was a man who understood
40:57the sense of loneliness
41:00that I felt.
41:03Can I ask you one last question?
41:06Yes.
41:07What kind of existence
41:10do you want science to be?
41:13I often use the phrase
41:16that science does not lie
41:19and that science is not plural.
41:22Science has no will,
41:25so it can be used for both
41:28good and evil.
41:31The question is
41:34how to control it.
41:37We need to look at the truth
41:40and look at the whole picture
41:43and figure out
41:46what this position is.
41:51The year after the incident,
41:54the Metropolitan Police Department
41:57established a scientific investigation agency
42:00and was given the same investigation rights
42:03as the police.
42:06The first scientific investigator
42:09was Mr. Harafuji.
42:12He was involved in many difficult cases.
42:17Lucy Blackman,
42:20who was kidnapped and killed by an English woman,
42:23went missing.
42:26Mr. Harafuji identified the drugs used
42:29and contributed to the arrest of the culprit.
42:36He is 67 years old and still works
42:39as the Chief Inspector.
42:42He cooperates with civilians
42:45and continues to develop
42:48scientific investigation technology.
42:51Mr. Oshita,
42:55who became a doctor,
42:58transferred to the medical field
43:01and is supported by drug addicts.
43:0630 years after the incident,
43:09the scientific investigation agency
43:12now employs more than twice as many people
43:15as it did at the time.
43:18Technology has evolved significantly
43:21and the traces of drugs
43:24can be traced back more than a year.
43:273D printer technology
43:30can preserve the condition
43:33of a destroyed building
43:36for a long period of time.
43:39The use of 3D printer technology
43:42for investigation
43:45was Mr. Oshita's idea.
44:10In July 2018,
44:13the execution of Asahara and Tsuchiya
44:16was carried out.
44:23The organization that honors Asahara
44:26as a martyr
44:29is still active.
