TOKYO (AP) -- The Japanese government said Monday that donations made by the prime minister to a controversial war shrine and visits by three Cabinet ministers were done in an unofficial capacity, while neighbors China and South Korea lodged protests over the actions.
The Yasukuni Shrine honors Japanese wartime leaders convicted of war crimes among 2.5 million Japanese killed in fighting during World War II. The shrine compound has a war museum that glorifies Japan's wartime past, and the site is a focus of nationalist pride among Japanese conservatives and right-wingers.
Visits to the shrine by political leaders are routinely criticized by South Korea, as well as China and North Korea, which bore the brunt of Japan's pre-1945 militarist march through Asia. The visits are regarded as evidence that Japan's leaders do not acknowledge their country's responsibility for its colonialist past.
Dozens of parliamentarians campaigning for official visits to the shrine are set to make a group visit Tuesday, likely to invite more protests. A separate group of ultra-nationalists are to approach a set of East China Sea islands at the center of territorial spat between Japan and China, further complicating the problem.
Top Japanese government spokesman Yoshihide Suga said that Prime Minister Shinzo Abe didn't visit the Yasukuni Shrine but donated religious ornaments marking the shrine's spring festival with the title "prime minister" on it. The finance minister and two other Cabinet ministers prayed at the shrine over the weekend.
"My understanding is that the three ministers paid visits to the shrine in their private capacity," Suga told a news conference. "There is no government comment to their shrine visits as private citizens."
But at least one Cabinet minister, National Public Safety Commission chief Keiji Furuya, told reporters that he prayed as a state minister during his visit Sunday but privately paid his donation money.
"As a national lawmaker, it is only natural to offer prayers to the sacred spirits who sacrificed their lives for the country," Furuya said.
Suga acknowledged reports that South Korea cancelled foreign ministerial talks but said the talks for later this month were at a planning stage and weren't official.
In Seoul, a Foreign Ministry spokesman expressed "deep concern and regret" over the actions by Abe and the other Cabinet members, calling Yasukuni a place that "glorifies Japan's wars of aggression that caused huge losses and pain to the peoples of neighboring countries."
South Korea "once again strongly urges the Japanese government to immediately stop its retrograde behavior which ignores history" and take responsible measures to restore confidence among neighboring countries, spokesman Cho Tai-young told reporters.
China's Foreign Ministry said it lodged a diplomatic protest Monday over the "negative moves." Spokeswoman Hua Chunying said in Beijing that how Tokyo treats the Yasukuni Shrine is a test of Japan's ability to respect people in the countries it attacked in the past.
"People of the whole world, including the Chinese people, are watching them. There is a mountain of iron-hard evidence for the crimes committed by Japanese invaders during the Second World War. Only by facing up to and deeply reflecting on the history of aggression can Japan possibly create a future and develop friendly and cooperative relations with the people of Asia," Hua said at a daily media briefing.
The weekend visits came amid increased tension between Northeast Asia's political giants. Japan is at odds with South Korea over an island group in the Sea of Japan that Seoul has controlled since the 1950s, and is increasingly at odds with China over a group of small islands in the East China Sea that both countries claim.
Suga said Monday that the shrine visits and donations were private and shouldn't affect diplomacy.
"Each country has its own stance on different issues. We should not let these things affect diplomatic relations," Suga said.
Abe last visited the shrine in October, when he was opposition leader.
