U.S. President Bill Clinton will fly to Japan for a one-day visit to attend the official funeral of the late Prime Minister Keizo Obuchi, a White House official said Thursday.

National Security Adviser Sandy Berger told reporters that Clinton will leave here for Tokyo on June 7, after winding up his May 30-June 5 tour of Germany, Portugal, Ukraine and Russia.

The president will attend the funeral slated for the following day, flying back to Washington immediately after the service, Berger said.

"The president believes that it is extremely important, given the fundamental importance of the U.S.-Japan relationship, that the United States express its solidarity with the Japanese people and its support for our partnership," Berger said.
