The Liberal Democratic Party installed new executives Thursday, introducing a fresh lineup to help LDP President Sadakazu Tanigaki prepare for the fall Diet session.
Nobuteru Ishihara, 53, the oldest son of Tokyo Gov. Shintaro Ishihara, replaced Tadamori Oshima, 64, as secretary general, while Oshima was assigned the vice presidency of the top opposition party.
Former Defense Minister Yuriko Koike became the first woman to assume an executive post in the LDP with her promotion as chairman of the Executive Council, while Shigeru Ishiba, chairman of the Policy Research Council, retained his post.
