Tax authorities have filed complaints with prosecutors against three business consultants and three of their clients over concealment of some 1.5 billion yen in income.

The three consultants are Terutsugu Suzuki, 49, a former auditor at Tokyo-based consulting company Neo Guild; Shinichiro Kinoshita, 45, a former president of the company; and an unnamed 50-year-old employee of an accounting company.

The clients are Eiji Yamada, 37, president of three entertainment production companies; Daishiro Miura, 72, former head of Bungei-za, a movie theater in Tokyo's Ikebukuro district that went bankrupt in 1997; and an unnamed man from Hyogo Prefecture.
