Japan issued a landmark apology on the 50th anniversary in 1995 under then-Prime Minister Tomiichi Murayama, for the first time acknowledging its colonization and aggression in parts of Asia before and during the war. In 2005, then-Prime Minister Junichiro Koizumi also apologized.
A key question is whether Abe will use the same terms such as "colonial rule" and "aggression" in his statement.
Abe told the panel he hopes to get their views on what Japan has learned from the past, how Japan has contributed to international peace in the postwar era and what Japan's regional and international contribution should be in the future. He did not refer to the apology, and panel members said they are not bound by the specific words used in past statements.
Abe, who took office in late 2012, initially signaled his intention to revise the 1995 apology, triggering criticism from China and South Korea. He now says his Cabinet stands by the apology, but that he wants to issue a more forward-looking statement, raising speculation that he will somehow water it down.
He said the panel will suggest possible elements for the statement and will not decide exactly what Abe will say.
About one-third of the panel members are regulars on Abe's policy advisory committees, like Kitaoka, though they exclude his associates with the most extreme right-wing views.
The appointment of centrist Asia experts Takashi Shiraishi and Shin Kawashima and a journalist from the liberal-leaning Mainichi newspaper give the panel some balance, but some other members stand out as historical revisionists.
