A committee in Japan's Liberal Democratic Party has asked the Japanese government to enshrine a "Takeshima Day," for the Japanese name of Korea's Dokdo, in law to assert the country's claim to the islets, the Sankei Shimbun reported Tuesday.

The call comes after Korea announced plans to set up an ocean science research station on Dokdo, which in turn was prompted by the Japanese government's approval of school textbooks that state Tokyo's claim.

The committee in the right-wing LPD, which was the ruling party for decades, also asked the Japanese government to establish an agency specifically tasked with dealing with Dokdo-related issue.

In a meeting Tuesday, former cabinet secretary Hiroyuki Hosoda said Tokyo must take "responsive measures," including declining Korean aid for Japanese earthquake victims and denying the Korean ambassador to Japan access to government officials.
