Three men, including a yakuza gang boss affiliated with Yamaguchi-gumi, Japan’s largest crime syndicate, have been arrested on suspicion of illegally supplying workers for government-commissioned decontamination work related to the 2011 Fukushima nuclear power plant accident.

The three are yakuza group leader Hidenobu Maruta, 48, of Tokyo’s Katsushika Ward, construction company executive Shigeki Yamamura, 59, of Koriyama, Fukushima Prefecture, and Akio Kitano, 51, an unemployed resident of Saitama, Tokyo police announced Sept. 27.

All three deny the allegations of employment brokering without a license, a violation of the Employment Security Law, and intermediate exploitation, which is banned under the Labor Standards Law.

Maruta and Yamamura are accused of supplying two workers from January 2015 to March 2016 to a sub-subcontractor who carries out decontamination operations for the government project, and receiving 160,000 yen ($1,430) together in commission without consent from the labor ministry.

The cleanup work was conducted in Tomioka, Fukushima Prefecture.

Maruta and Kitano are suspected of taking commission amounting to about 920,000 yen from the wages of those two workers, according to the police department in charge of organized crime.

The three suspects are said to have shared cut of 2,000 yen to 3,000 yen from each of the workers’ 16,000-yen daily wage.

Further to the exploitation of the aforementioned two workers, the suspects are believed to have received about 10 million yen collectively through brokering about 10 other workers to the sub-subcontractor.
