Kobe shootings: Kametani, Akada, the Mitsui ¥200 million allegations and the Shinjuku Building
Tracing the reported connections, bail money allegations and Shodoshima land negotiations
Two names in the Kobe shootings lead to older stories about Tokyo Station, alleged bail funds and a disputed Shinjuku property. What do the reports establish, and where do the rumors begin?
On September 30, 2026, shootings at two locations in Kobe left one man dead and another injured. The man who died was company owner Akada (赤田正行), 58. Police arrested former gang member Naoto Kametani (亀谷直人), 79, on suspicion of attempting to murder the other man.[1]
Kametani's name leads back to a 2002 killing near Tokyo Station and allegations about ¥200 million connected to the case of former senior prosecutor Tamaki Mitsui (三井環). Akada's name also appears in reports of a 2018 arrest concerning the former Shinjuku Building site (真珠宮ビル跡地).[3][4][9]
Do those older cases help explain the Kobe shootings? This article traces the reported connections, the origins of the rumors, and developments reported through the evening of October 1.
What happened in Kobe, and how were the three men connected?
On the afternoon of September 30, Akada was shot and died in Kobe's Chuo Ward. A 54-year-old man was subsequently shot and injured in Hyogo Ward. Kametani was arrested in connection with the Hyogo Ward shooting and reportedly made statements suggesting involvement in the fatal shooting in Chuo Ward.[1]
Kansai Television reported on October 1 that Kametani appeared to know both victims. A senior investigator said that, at that point, there was no information indicating a conflict between gangs.[1]
A reported request to buy land on Shodoshima
In an article published at 11:04 p.m. on October 1, the Kobe Shimbun reported an account from a construction company president who lived at the house where the second shooting occurred. He said that, around May that year, the man who later died had asked him to buy land on Shodoshima associated with Kametani's side, and that he declined. Police were investigating whether a problem involving the land transaction contributed to the shootings.[2]
The newspaper also reported that Kametani and both victims appeared to have been traveling in the same car. Why did they meet, and what happened during the land negotiations? Those specific circumstances are relevant to understanding the current case.[2]
Kametani, the 2002 Tokyo Station killing, and the alleged missing ¥200 million
On November 25, 2002, 鶴城丈二, the head of the Yamaguchi-gumi affiliated Kyoyukai, was shot dead near the Yaesu entrance of Tokyo Station. A reproduction of a contemporaneous Kyodo report says Kametani was arrested at the scene and that a driver accompanying the victim was also injured.[3]
Journalist Toshiaki Furukawa subsequently wrote that Kametani received a 20-year prison sentence for the incident. Reporting after the current arrest also discusses his lengthy imprisonment.[4][5]
One account offered for the background of the Tokyo Station killing involves ¥200 million allegedly intended to secure bail for Kanekichi Kuwata (桑田兼吉), then the third leader of the Yamaken-gumi.
Rumor 1: failed bail arrangements and a dispute over repayment preceded the 2002 killing
The blog 日本の黒い霧 presents an account in which the Yamaken-gumi provided Kametani with ¥200 million for efforts to obtain Kuwata's release on bail. It says the release did not happen and a dispute developed between Kametani and 鶴城.[6]
That account concerns the alleged background of the 2002 killing. It is not an official explanation for Akada's death in 2026. The money is described as funds for arranging bail, rather than a bail security deposit paid to a court.[6]
Accounts of the money's ultimate whereabouts differ. Furukawa's reporting discusses alternative information about intermediaries and repayment, while identifying parts he could not verify. The public material obtained for this article does not establish who retained how much or what was returned.[7]
The Mitsui case: allegations of a deal with prosecutors
Tamaki Mitsui headed the public security division of the Osaka High Public Prosecutors Office. He was arrested in 2002 while preparing to expose alleged misuse of prosecutors' investigation funds. Mitsui maintained that his arrest was intended to prevent his disclosure.[18] He nevertheless received a prison sentence. JBpress, which interviewed him, describes his unsuccessful challenge through the Supreme Court and a sentence of one year and eight months.[8]
Rumor 2: cooperation in the Mitsui investigation was exchanged for Kuwata's bail
The same blog alleges that Kametani's cooperation in the Mitsui investigation was tied to Kuwata's release on bail. An April 2003 article in Shikoku Times also linked the ¥200 million to approaches to prosecutors, using explanations attributed to anonymous sources.[6][10]
This raises questions about funds allegedly obtained on claims that connections with prosecutors could secure bail. However, no judgment establishing such a deal or payments to prosecutors was found in the material reviewed.
Courts decide whether to grant bail. The courts' official explanation describes release subject to specified conditions. Claims of connections with prosecutors, the power to make a bail decision, and evidence of an actual payment are distinct matters requiring their own evidence.[11]
The expression “Mitsui's missing ¥200 million” can itself mislead. It does not establish that Mitsui received the money or lost funds of his own. Here, it refers to allegations about money for Kuwata's bail arrangements that have been discussed in connection with the Mitsui case.
Akada and the former Shinjuku Building site: what the 2018 arrest reports establish
The 2018 series published by 週刊報道サイト says Osaka police arrested three people on August 21 that year, including a Kobe company officer named 赤田正行, then 50. The allegation concerned a false registration of a provisional attachment against the former Shinjuku Building site in January 2016.[9]
The name, residential area, and age progression are consistent with the man who died in Kobe eight years later. This makes it likely that the reports concern the same person. That is an inference from matching public reports, however; an official identity record confirming the match was not obtained.[1][9]
The outcome after the 2018 arrest—including any prosecution decision or judgment—has not been established in this research. An arrest on suspicion of false registration does not, by itself, establish a conviction for fraudulently obtaining land or justify adding such a conviction to someone's history.
The original building case and the later site case are different proceedings
真珠宮 is read “Shinjuku.” The building, near Shinjuku Station, was the subject of a complicated ownership dispute. In 2006, 野崎和興 was killed, and people were also arrested in a case involving false ownership registration.[12][13]
Akada's name appears in the later provisional attachment registration case. The reports from 2006 and 2018 concern different alleged acts at different times.
| Person | Court outcome supported by the material reviewed |
|---|---|
| Tadamasa Goto (後藤忠政; legal name 忠正) | Acquitted at first instance in the ownership registration case, then convicted on appeal. The Supreme Court rejected his appeal in 2012.[14] |
| Susumu Nishioka (西岡進) | The former Hishiwa Life Create president was acquitted at first instance in 2007. A lawyer's account says the prosecution did not appeal and the acquittal became final.[15][16] |
| 松本英也 | A Tokyo District Court judgment in 2013 found that he directed 野崎's killing and imposed life imprisonment. The judgment confirmed in this research is the first-instance decision.[13] |
| 赤田正行 in the 2018 reports | Reports of arrest on suspicion of false provisional attachment registration. The final disposition has not been confirmed.[9] |
These outcomes do not establish that Akada participated in the 2006 killing.
Why the three cases are linked in speculation
People connect these stories because the same names and property transactions recur:
- Kametani's history includes the Tokyo Station killing and allegations about money for bail arrangements.
- Akada's name appears in reporting about registration of the former Shinjuku Building site.
- A witness account in the current case also concerns negotiations to buy land.[2][3][6][9]
That overlap can prompt speculation about old financial disputes or property interests. But the material obtained does not trace the ¥200 million discussed in relation to 2002, funds for the former Shinjuku Building site, and the 2026 Shodoshima negotiations as one continuous flow of money.
Rumor 3: did the missing ¥200 million go into the former Shinjuku Building site?
An older blog illustrates how destinations can be confused. An April 2018 post on MS blog Asia discusses the Shinjuku Building registration case and the Yamaken-gumi's ¥200 million in the same article. Yet the destination it names for that money is 原町共栄クリーン, not the former Shinjuku Building site. It is not documentation of a payment into that property. This remains the blog's account; underlying records substantiating the alleged transfer were not obtained.[17]
Cases appearing on the same page, personal connections, and recurring organization names do not establish where funds went. An argument that money was shared would need payment, contract, bank, or accounting records.
The suggestion that an old feud motivated the current shootings also remains speculative. Establishing the rights to the Shodoshima land, the negotiations, the purpose of the three men's meeting, and what was said before the shootings could clarify whether any older connection mattered.

Frequently asked questions
Do “消えた二億円” and “消えた2億円” refer to the same allegations?
In this article, they do. Both refer to allegations about funds for arranging Kuwata's bail that have been discussed in connection with the Mitsui case. Different accounts give different explanations of the money's whereabouts. The label alone does not identify a final recipient.
Did Akada receive the Yamaken-gumi's ¥200 million?
The material reviewed on the money principally concerns Kametani, 鶴城, and others. This research found no substantiation that Akada received those funds.[6][7] His name in the later registration case should not be treated as proof of participation in the earlier financial allegations.
Was Akada a convicted land fraudster?
The established reporting is an arrest allegation about a company officer with the same name. The final disposition and any judicial finding of criminal conduct have not been confirmed. It would therefore be unsupported to describe him as convicted of land fraud.[9]
Were the Kobe shootings gang warfare or an attempt to silence someone?
A senior investigator quoted by Kansai Television said there was no information indicating gang warfare at that point.[1] Earlier incidents and personal histories also do not establish a silencing motive in the current case. The motive remains under investigation.
What would help clarify the case?
Kametani's past includes a killing near Tokyo Station. Akada's name matches older arrest reporting concerning the former Shinjuku Building site. The current reporting adds an account of land negotiations.
That overlap warrants examining the history. The immediate questions are why the three men met, who held rights to the Shodoshima land, what was negotiated, whether money changed hands, and what led to the shootings. Those details would help assess whether older allegations have a concrete connection or whether the cause lies in the current dealings.
