TOKYO - German Chancellor Angela Merkel, referring to Germany's own experience, reminded Japan on Monday of the need to squarely confront its wartime past.

The polite reminder comes as Prime Minister Shinzo Abe is preparing to issue a statement to mark the 70th anniversary of Japan's defeat in World War II, the legacy of which still plagues Tokyo's ties with China and South Korea.

The statement will be closely watched by Beijing and Seoul, which suffered under Japanese militarism, as well as Tokyo's close ally, Washington.

Abe has said he intends to express remorse over the war and that his cabinet upholds past apologies, including the landmark 1995 statement by then-premier Tomiichi Murayama. But it is unclear whether Abe will repeat the "heartfelt apology" and reference to "colonial rule and aggression" in that statement.

Some scholars say that Japan bears part of the blame for East Asia's inability to lay the ghosts of the war to rest because its conservative politicians often cast doubt on the sincerity of past apologies.

In a speech at the start of her first visit to Japan since 2008, Merkel referred to a 1985 speech by the late German president Richard von Weizsaecker in which he called the end of World War II in Europe a "day of liberation" and said those who closed their eyes to the past were "blind to the present".

Feuds over wartime history as well as territorial rows over disputed islands and geopolitical rivalry have frayed Tokyo's ties with Seoul and Beijing in recent years. Sino-Japanese relations have thawed a little since Abe met Chinese leader Xi Jinping last November but ties with Seoul remain frosty.
