Japan is considering holding informal talks with South Korea and other countries on a dispute over the name of the Sea of Japan, a top official has hinted, in what could become the latest in a series of diplomatic feuds between Tokyo and Seoul.

Chief Cabinet Secretary Yoshihide Suga said at a news conference Friday the government is contemplating the talks at the request of an intergovernmental organization that sets out guidelines on the international names of seas and oceans, and their boundaries.

Noting that Japan is a "responsible member" of the International Hydrographic Organization, Suga said the government will "make constructive contributions to the informal talks."
