Foreign ministers from Japan and South Korea are holding a rare meeting today on the eve of the 50th anniversary since their countries normalised relations marred by Japan's colonisation and World War II conquest.
Yet, the ties between the most important US allies in Asia are so low that one hoped-for outcome of the meeting is an agreement for the countries' leaders to just show up at tomorrow's ceremonies in their respective capitals, instead of exchanging written statements.
"It's a grave situation, and what's more serious is that Japan's diplomacy toward South Korea has turned harsher against the backdrop of public sentiment," said Junya Nishino, a political science professor at Keio University.
According to a poll by Japanese newspaper Asahi and South Korea's Dong-a Ilbo, published yesterday, more than half of the respondents in both countries say their image of the other side has worsened in the past five years.
The poll also found that 87 per cent of South Koreans feel strongly about better relations with their neighbour, compared to 64 per cent in Japan.
"Trust between Japan and South Korea has been largely lost, and it's not easy to restore it right away," said Nishino.
Japan's Prime Minister Shinzo Abe and South Korean President Park Geun-hye have yet to hold fully fledged bilateral talks since taking office in 2012 and 2013, respectively. Washington has been concerned about its allies' strained relations.
They are rooted in Japan's colonisation of Korea, from 1910 to the end of World War II.
The relations improved in the late 1990s, following Japanese apologies, cultural exchanges and a Korean pop culture boom in the 2000s, but nosedived a few years ago largely because of differences over their shared history.
Many Koreans still remember Japan's 35-year colonisation as the era of brutality and humiliation, during which they were forced to use Japanese names and language while their pride, heritage and sense of identity were severely threatened.
After normalising ties, it took three more decades before Seoul officially allowed Japanese films and other popular culture back into the country.
The latest downturn started in 2012, when then-South Korean President Lee Myung-bak visited a cluster of Seoul-controlled islets also claimed by Japan.
As public sentiment soured, ethnic Koreans in Japan, many of whom descendants of forced labourers, became target of racial insults by right-wing extremists.
