Tokyo - Major Japanese trading house Mitsubishi Corporation allegedly failed to report some 4.2 billion yen (38.62 million dollars) in tariffs on pork imports from Denmark, local media reports said Monday.

Mitsubishi allegedly reported paying more than the actual price in order to evade paying tariffs in 2005.

The government imposes tariffs on the difference in price between domestic products and imports, when the price of imported pork is lower than the standard of 524 yen per kilogram.

The tariff system was introduced in 1971 to protect domestic products.

The Tokyo customs office has imposed back taxes of about 4.5 billion yen on Mitsubishi. (dpa)
