An affiliate of the Postal Services Agency failed to declare about 120 million yen in income over a three-year period up to March this year, informed sources said.

The Tokyo Regional Taxation Bureau imposed additional taxes and penalties totaling some 30 million yen on the Postal Services Center.

The center, the public corporation that mediates delivery of "furusato kozutsumi" (parcels from hometowns), failed to declare a portion of its income derived from commission fees in its declaration, the sources said Saturday.
