Govt. posts historical data on Senkakus, Takesima

The Japanese government has posted new reports on its website to back its claim to the Senkaku Islands in the East China Sea and the Takeshima Islands in the Sea of Japan.

The findings were posted on the Cabinet Secretariat website and from studies by expert panels on these islands.

The latest report on the Senkakus includes an old document that suggests a member of the Ryukyu Kingdom's royal family landed on one of the Senkaku Islands in 1819.

The kingdom ruled most of Okinawa from the 15th to 19th century.

The government believes the document is the oldest record written about landing on the islands by any person. This was 26 years before the first landing of the British in 1845.

The report also points out that a map drawn up by China's Qing dynasty in 1744 did not have the islands as part of its territory. This indicates the dynasty had not recognized the islets.

Japan controls the Senkaku Islands. China and Taiwan claim them. The government maintains the Senkaku Islands are an inherent part of Japan's territory and that there is no issue of sovereignty to be resolved over them.

A newly posted report on the Takeshima Islands notes that a book compiled in 1955 by South Korea's government says no official documents were available that show the territory had been incorporated into the country's administrative boundaries.
