<h3>Men in hakama lined up in formation</h3>
<p data-start="89" data-end="293">On September 25, the headquarters of the long-established yakuza group Hirai-ikka, located in the suburbs of Toyohashi City, Aichi Prefecture, was enveloped in a tense atmosphere from early morning.</p>
<p data-start="295" data-end="744">Starting around 7 a.m., several investigators were stationed in front of the headquarters on alert. Their numbers gradually increased, and by 7:30, there were about twenty of them. In addition to the local Aichi Prefectural Police, officers from prefectural police departments across Japan — including Hokkaido, Chiba, Ibaraki, and Hyogo — had gathered. Surrounding them was a large crowd of reporters, giving the scene an air of palpable tension.</p>
<p data-start="746" data-end="903">The Hirai-ikka headquarters, enclosed by high walls, gave no hint of what was happening inside. However, just before 10 a.m., the shutters suddenly opened—</p>
<p data-start="905" data-end="1242">In front of the entrance, a line of stern-looking men in hakama stood in formation. Soon after, a black luxury car, escorted by a security vehicle, appeared, sending the tension at the scene to its peak. Stepping out was Teruaki Takeuchi (65), the head (sōsai) of Kōdōkai, one of Japan’s most powerful yakuza organizations.</p>
<p data-start="1244" data-end="1902"><strong>“On this day, the Hirai-ikka was hosting the succession ceremony (keishō sakazuki) for the new Kōdōkai chairman,” explains a journalist familiar with Yamaguchi-gumi affairs. “On September 8, Kōdōkai announced new appointments: Masahiro Nouchi, who had served as wakagashira (deputy boss), became the new chairman, while Takeuchi, who had previously been chairman (and wakagashira of the Sixth Yamaguchi-gumi), assumed the role of sōsai. Since both Kōdōkai and the Hirai-ikka are part of the Sixth Yamaguchi-gumi hierarchy — the former being a core group and the latter a secondary organization — the location was likely provided for that reason.”</strong></p>
<p data-start="1904" data-end="2408">Kōdōkai is renowned for having produced key figures such as Shinobu Tsukasa (83), leader of the Sixth Yamaguchi-gumi, and Seiji Takayama (78), its senior advisor. Given that this was a leadership transition at the top of such a central organization, the ripple effects are expected to influence not only the Sixth Yamaguchi-gumi but the entire underworld. Authorities recognized the gravity of the event — the number of investigators on guard continued to rise, reaching around forty by 11 a.m.</p>
<p data-start="2410" data-end="2753">About an hour and a half after Takeuchi entered the building, the shutters opened once again. Inside, Takeuchi could be seen getting into a car, while Nouchi stood by to see him off. Takeuchi then departed in his convoy, led by a security vehicle. From Nouchi’s relieved smile, it was clear that the sakazuki ceremony had concluded safely.</p>
<p data-start="2755" data-end="2907">According to an organized crime expert, this leadership change represents a move to carry forward the ideology of Boss Tsukasa and Advisor Takayama.</p>
<p data-start="2909" data-end="3400"><strong>“Typically, personnel changes within the Sixth Yamaguchi-gumi are finalized between autumn and December, before the traditional Shigoto-hajime (year-start ceremony). However, this year, they even held an extraordinary executive meeting in August, signaling urgency in building a new structure. The timing — just before August 27, marking ten years since the start of the split conflict with the rival Kobe Yamaguchi-gumi — shows a strong determination to reinforce internal governance.</strong></p>
<p data-start="3402" data-end="4016"><strong>The reshuffling of the Sixth Yamaguchi-gumi’s leadership continues. Of the executives who were in office during the split, only Takeuchi and shatei-gashira Utao Morio remain. The organization’s rejuvenation and reforms centered on Takeuchi are steadily progressing. Within this context, the movements of Kōdōkai — the core of the Sixth Yamaguchi-gumi — are of critical importance in predicting the syndicate’s overall future direction. The lineage from Tsukasa (Boss) → Takayama (former deputy) → Takeuchi (deputy) now continues to Nouchi, marking a deliberate step in the succession of the Kōdōkai tradition.”</strong></p>
<p data-start="4018" data-end="4148" data-is-last-node="" data-is-only-node="">A major turning point for this prestigious organization is now poised to exert significant influence across the entire underworld.</p>

 Takeo Shintai

 On September 25, strong men in hakama gathered in a quiet residential area in Toyohashi City, Aichi Prefecture. What was taking place was a "sake meeting for the succession of the chairman" of the Kodokai, the core organization of the Yamaguchigumi VI. We report the inside story with tense photos of the scene.
