The president of the Blue chain of sex clubs, Yoshinori Sato, 56, was sentenced to two years and six months in prison for making threatening phone calls to the home of the investigator on five occasions between July and August of 2010. The prosecution had sought three years and six months.
The officer was investigating whether the Kodo-kai organized crime group, an affiliate of the Yamaguchi-gumi, was utilizing the Blue group as a source of funds.
In September, Aichi Prefectural Police arrested Katsunori Kuraki, an inspector within the first investigative division, for allegedly leaking confidential information to Sato.
Sato was previously arrested in 2011 for assisting in concealing the identity of the number-two boss of the Kodo-kai during a round of golf. Sato received a prison term of two years and six months, which was suspended for four years.
