OSAKA -- Tax authorities have fined the chairman of a social welfare institution about 200 million yen for concealing about 310 million yen in income related to construction of a nursing home, sources said Thursday.

According to sources in the Osaka Regional National Taxation Bureau, Ichio Maeda, 44, chairman of the welfare institution Energy Life, in Kakogawa, Hyogo Prefecture, failed to declare about 310 million yen he received from Akashika Construction Co. in Himeji, Hyogo Prefecture. The construction firm had won a 1.34 billion yen contract to build an Energy Life nursing home in Kakogawa that opened in April 1998.

Maeda has reportedly complied with the fine, they said.

The tax authorities also fined Akashika Construction about 180 million yen for padding tax-exempt expenses, they said.
