The Japanese Embassy in Moscow wasted about ¥10 million in telephone charges in three years up to March because its phones were almost not used after the mission was relocated in 2007, the Board of Audit reported Friday.

The embassy paid ¥11.72 million in basic charges for five optical-cable telephone numbers after canceling contracts with a local telecom firm for 21 other numbers when the embassy was relocated.

While the contract was reduced, the embassy continued to pay the basic charges for the 26 numbers after its relocation.

As there were almost no phone calls using the five numbers during the three years, the embassy had to pay only about ¥900,000 in phone charges.
