South Korean officials are hopeful that Kishida will make some kind of gesture in return and offer some political support, although few observers expect any further formal apology for historical wrongs. But the historical differences between South Korea and Japan also threaten to cast a shadow over the blossoming ties between its two leaders. The majority of South Koreans believe Japan hasn't apologised sufficiently for atrocities during Japan's 1910-1945 occupation of Korea, Lee said. "They think that Prime Minister Kishida should show sincerity during his visit to South Korea, such as mentioning historical issues and expressing apologies," she added. Still, South Korea is an "important neighbour that we must cooperate with on various global issues," Japan's foreign ministry has said.
