Entertainment production firm Rising Production Co., which counts pop stars Namie Amuro and Da Pump in its stable, was found by tax officials to have evaded taxes on income of 2 billion yen in the three years to August 1999, sources said Tuesday.

The Tokyo Regional Taxation Bureau plans to file a criminal complaint as the amount of unpaid taxes is excessively large at over 500 million yen and the Tokyo-based firm used "malicious" means as logging fictitious expenses to hide its income, the sources said.

The firm revised its tax report after the discrepancies were discovered.
