Poll: Japanese opinion of South Korea up from 10 years prior
This latest joint public opinion survey was conducted by The Asahi Shimbun and South Korea's Dong-A Ilbo to mark the 60th anniversary of the normalization of diplomatic relations between Japan and South Korea.
On the Japanese side, those who said they 'like' South Korea increased from 10 percent in 2015 to 19 percent this time around. Those who felt that Japan–South Korea relations are 'going well' rose from 7 percent to 29 percent.
Even so, views on the future of the bilateral relationship remained mostly unchanged from a decade ago, with only 17 percent of Japanese respondents believing ties will move in a 'positive direction.'
BILATERAL FEELINGS IMPROVED
This year's survey was conducted by phone in both countries, while the 2015 joint survey relied on the post on the Japanese side, making a direct comparison of the figures difficult.
However, compared to the strained relations at that time, in the wake of events such as the 2012 visit by then South Korean President Lee Myung-bak to Takeshima, known as Dokdo in South Korea, and the 2013 visit by then Prime Minister Shinzo Abe to Yasukuni Shrine, current relations appear more favorable.
On the South Korean side, those who said they 'like' Japan increased from 5 percent in the previous survey to 23 percent. Those who said they 'dislike' Japan dropped from 50 percent to 23 percent, while those who answered 'neither' increased from 43 percent to 54 percent.
In Japan, older age groups were less favorable toward South Korea 10 years ago. However, in the survey this time, age differences were small, except that only 12 percent of respondents in their 40s answered that they like South Korea.
Twenty-two percent of those in their 60s and the same ratio of those in their 30s answered that they liked South Korea.
The proportion of people who said they 'dislike' South Korea was especially low among those in their 30s and younger, at around 5 percent. Among older generations, the figure was around 15 percent, with little variation by age.
When asked about the current state of Japan–South Korea relations, 29 percent of Japanese respondents said the relationship was 'going well,' while 50 percent said it was 'not going well.'
In the previous survey, those figures were 7 percent and 86 percent, respectively. So, the survey this time showed a significant improvement.
On the South Korean side, 3 percent of the respondents said it was 'going well' and 90 percent said it was 'not going well' the last time. But the numbers shifted to 26 percent and 59 percent, respectively, this time.
However, when asked about the future of Japan--South Korea relations, Japanese optimism remained low. Only 17 percent responded that the relationship would go in a 'positive direction,' nearly unchanged from the 15 percent of 10 years ago.
Those who said it would go in a 'negative direction' was 14 percent, which increased from 10 percent in 2015, and those who believed it would 'remain the same' were 61 percent, decreased from 67 percent in 2015.
While the Japanese outlook for future Japan–South Korea relations remains cautious, South Korean respondents showed a more positive trend.
Those who said the relationship would move in a 'positive direction' doubled from 22 percent to 42 percent, making it the most common response. Those who expected it to worsen increased from 11 percent to 20 percent, and those who said it would remain the same dropped from 60 percent to 31 percent.
HISTORICAL TENSIONS REMAIN
In the joint poll, respondents were also asked about historical issues, including Japan's colonialization of the Korea Peninsula from 1910 to 1945.
In Japan, opinions were evenly split: 46 percent respondents said the issues had been 'resolved,' while the same percentage of respondents said they had 'not been resolved.'
In South Korea, 17 percent said the issues had been 'resolved,' up from 2 percent a decade ago, while those who said they had 'not been resolved' dropped from 95 percent to 80 percent.
Although there are signs of a shift toward a more future-oriented perspective, a considerable gap in perceptions of historical issues still remains between the two countries.
This year's survey was conducted by telephone in both countries. In contrast, the 2015 joint survey was conducted via postal mail in Japan, so a direct numerical comparison is difficult. At that time, 49 percent of Japanese respondents said the issue had been resolved, while 42 percent said it had not.
Respondents were also asked whether they believed Japan had sufficiently apologized for its annexation of Korea and colonial rule.
In Japan, 67 percent said the country had 'apologized sufficiently,' while 22 percent said the apologies were 'still insufficient.' These numbers were similar to the 2015 results, with 65 percent and 20 percent, respectively.
In South Korea, 13 percent said Japan had 'apologized sufficiently,' while 85 percent said the apologies were 'still insufficient.'
These figures on the South Korean side reflect a certain degree of change from 10 years ago when 1 percent were satisfied with the apology and 96 percent said it was not enough.
However, the majority still believe Japan's attempts to make amends are not enough.
Regarding the historical issues in Japan–South Korea relations, the two governments agreed at the end of 2015 that the issue of wartime 'comfort women' was 'finally and irreversibly resolved.'
Despite this shared official stance, strong domestic criticism in South Korea against the agreement has been persistent, and effectively became a mere formality following the change in the South Korean administration in 2017.
Regarding the issue of wartime mobilized workers, the South Korean Supreme Court ordered Japanese companies to compensate the South Korean wartime laborers in 2018.
The companies did not comply with the order. Under then President Yoon Suk-yeol, the South Korean government proposed a solution in 2023 where a state-affiliated foundation would provide compensation on behalf of the Japanese companies, funded by donations.
FINDING PARTICIPANTS
On the Japanese side, The Asahi Shimbun carried out the survey with eligible voters on June 7 and 8, using both landline and mobile phone numbers that were randomly generated by computer. A total of 1,124 of 2,824 voters who received the phone call provided valid responses
The Dong-A Ilbo conducted the survey in South Korea through a private research institution. The survey was conducted on those 18 and older on June 9 and 10 using mobile phone numbers that were also randomly generated by computer.
A total of 1,010 of 13,828 people who received the phone call provided valid answers to the survey.

Bill Emmott: Japan should lead regional collaboration to cope with Trump 'typhoon'
By Bill Emmott, independent writer, lecturer and international affairs consultant During all the decades of the U.S.-Japan security alliance, which has been one of the closest security partnerships anywhere in the world, Japan has had to worry about two contradictory dangers: abandonment and entrapment. Abandonment would involve Japan's interests being ignored by its partner amid a deal with one of its enemies; entrapment would mean being forced to fight alongside the United States in a war chosen by the Americans but not by the Japanese. These worries about extreme outcomes have tended to alternate, depending on the political mood in Washington, DC, at the time. Yet currently Japan finds itself worrying about both abandonment and entrapment simultaneously. This may be as good a sign as any that the Trump administration represents a sharp break with the postwar past. The entrapment fear has always felt the likelier danger. It has now reared its head again in a surprising way, as senior US defence officials have been reported to have been pressing Japan and Australia to make explicit commitments about whether they would fight to defend Taiwan in the event of an attempted Chinese invasion or coercion. The surprise is that American officials are pressing such close allies for an explicit commitment when not even the United States itself, and especially not its Commander in Chief, President Donald Trump, has made its own intentions clear. This is not a total break with recent American administrations, but it does put Japan in a potentially awkward position. During the Biden administration a mutual concern over the security and stability of Taiwan did begin to feature in the US-Japan communiques issued after meetings between the Japanese prime minister and the U.S. president, showing that some sort of explicit commitment to working together to preserve the status quo was being sought by the United States. However, that is not the same, at least not politically the same, as actually committing yourself to fight a future war, in circumstances that cannot be predicted and without knowing what America's own stance would be. To do so would be politically extremely difficult, especially for a government that currently lacks a majority in the Diet. Beyond domestic politics, the immediate risk would not be of a war itself but rather of such a commitment causing a further worsening of Japan's relations with China, to no obvious purpose. Abandonment has always looked the less likely of the twin dangers, for having Japan as its largest overseas military base has mattered so much to America and its regional presence in the Indo-Pacific that the idea of it deserting its Japanese ally has looked implausible. This remains true, especially given the emphasis being laid by leading figures in the Pentagon and the Republican Party on the contest with China for both regional and global supremacy. However, President Trump is well known to be highly transactional, especially in foreign policy. He has also indicated a strong sympathy for the very 19th century idea that great powers are entitled to have "spheres of influence" in the areas around their own borders. He has, for example, expressed a determination that America should gain control over Greenland, the icy territory that is part of Denmark but adjacent to the north-east coast of the United States, has declared that Canada should become the U.S.'s "51st State," and has insisted the U.S. should regain control over the Panama Canal. This makes it conceivable, even if still improbable, that at some point Trump could be tempted to accept Chinese control over its "sphere" of Taiwan and the South China Sea in return for China accepting US control over territories in its region. That would give China control over the main sea lanes surrounding Japan and a greatly increased ability to intimidate other countries in the region, including Japan, South Korea and the Philippines. This is, admittedly, a rather extreme scenario. The identification by most members of Trump's Republican Party of China as America's leading global adversary, and the strong support for Taiwan held by those same Republicans, makes it feel especially unlikely. Yet the fact that the idea of such a "grand bargain" with China is talked about at all simply underlines how unpredictable is the foreign policy of this American president, with the range of actions and outcomes during the remaining three and a half years of his term looking wider than under any U.S. president in living memory. The governments of every longstanding ally of the United States are having to live with this uncertainty, one which reflects a broader question: using a meteorological metaphor, does Trump represent a temporary extreme-weather event, like an especially severe typhoon, or does he represent climate change, a trend that will endure? The safest answer is that he is a bit of both: his extreme volatility and hostile manner can be seen as personal and thus temporary, but some of the ideas he is purveying have a broader resonance in the United States that could persist after he is gone. The central role that America plays in the security of the Indo-Pacific gives Japan little choice other than to adapt to whatever extreme weather emerges from Washington, DC. The more forward-leaning stance Japan has taken on defence, first under Prime Minister Shinzo Abe and then with the new National Security Strategy under Prime Minister Fumio Kishida in 2022, has had the dual purpose of increasing Japan's contribution to joint deterrence operations with America and creating more long-term options for national security in case relations with Washington become more fractured. Continuing and even enhancing this strategy remains Japan's only viable plan. What Japan could perhaps invest even more time in is in its already impressive diplomatic efforts in north-east and south-east Asia. To cope with the Trump "typhoon" and to increase Japan's own leverage over Washington at any time of crisis, it makes sense to work more closely with other countries that face the same pressures, starting with South Korea but also extending south to Vietnam, the Philippines, Indonesia and Taiwan itself. All these countries are facing hostility from Trump over trade while also needing to invest more in their own security and economic resilience, in a region in which the two superpowers, China and the U.S., are both unavoidable presences but also habitual bullies. It therefore makes sense to work together on trade, technology, security and other issues as much as possible, to increase bargaining power as well as resilience. Japan has a key role, as well as opportunity, to drive this regional collaboration. The contradictory fears of entrapment and abandonment can never be eliminated, but through collaboration they can perhaps be mitigated.

Japan, U.S. discussing scenario for nuclear weapons use: sources
TOKYO - Japan and the United States have been discussing a scenario, in which the U.S. military would use nuclear weapons in the event of a contingency, during talks on so-called extended deterrence, sources close to the two countries said Saturday. It is the first time the allies have delved into the issue, in a sign that they are seeking to strengthen the U.S. nuclear umbrella, under which Japan is protected, amid intensifying military activity by China, North Korea and Russia, the sources said. Japan is the only country to have experienced an atomic bomb attack and has long advocated for a nuclear-free world. However, it also relies on the U.S. nuclear umbrella for defense. The United States dropped an atomic bomb on Hiroshima on Aug. 6, 1945, and a second one three days later on Nagasaki in the final days of World War II. As part of the extended deterrence talks in recent years, Tokyo and Washington have held multiple tabletop exercises to strategize a scenario in which a conflict broke out in East Asia and the United States is pressured to use nuclear weapons, according to the sources. With that in mind, Japan and the United States reviewed how to coordinate and how to deal with issues stemming from the possible use of nuclear weapons, such as managing public opinion. Discussions also broached how much information the United States can share with Japan, the sources said. In December, the countries announced their first guidelines for extended deterrence -- including U.S. nuclear protection -- to better tackle regional security challenges. But details were not revealed due to the sensitivity of information related to national security, according to a senior Japanese Foreign Ministry official. Diplomatic sources said the guidelines stipulated the steps the countries would take should the United States use nuclear weapons under Article 5 of the bilateral security pact. Article 5 obliges the United States to defend territories under Japan's administration from armed attack. The sources close to the nations also said the guidelines made it clear that Japan can convey its thoughts on a possible nuclear weapons use. Since extended deterrence talks were established in 2010, senior-level discussions, led by top foreign affairs and defense officials, have been held once or twice a year. The dialogue was upgraded in July 2024, with the first-ever ministerial talks on the issue held in Tokyo to better coordinate the alliance with an eye on China's military buildup and North Korea's missile and nuclear development.

Japan, U.S. ministers reached trade agreement in mid-June: sources
TOKYO - Japan's chief negotiator reached an agreement with U.S. Commerce Secretary Howard Lutnick in mid-June on a deal offering massive Japanese investment in the United States in exchange for a reduction in tariffs, sources close to the matter said Saturday. Over the following month, Japan focused on convincing U.S. President Donald Trump through Lutnick of the advantages of the agreement, with the proposal of expanding imports of U.S.-grown rice used as the final bargaining chip. The trade deal, announced by Trump on July 23, includes tariffs on Japanese cars set at 15 percent -- lower than the 27.5 percent that was to have been levied -- in exchange for $550 billion of Japanese investment in the United States. During the course of the negotiations, which spanned around three months from mid-April, Japan identified Lutnick as the only person who could communicate "directly and on a deep level" with Trump due to their close friendship of over 30 years, and directed its efforts on him, according to one of the sources. Ryosei Akazawa, Japan's chief tariff negotiator, built trust with Lutnick not only through in-person talks but also through dozens of phone calls, the source said. Believing that Lutnick placed a high priority on economic security amid China concerns, Japan emphasized its willingness to contribute to strengthening U.S. domestic supply chains and eventually reached an understanding with him. Trump, however, maintained a hardline stance even in late June, venting frustration that Japan does not import significant amounts of American cars and rice. "I'm not sure we're going to make a deal. I doubt it," he had said, while demanding additional concessions in exchange for lowering tariffs. The tide turned on July 22 immediately following Japan's upper house election. A sudden meeting was arranged for the following day between Trump and Akazawa, who was in Washington for an eighth round of talks. Akazawa and Lutnick began to "rehearse" in preparation for the talks, with Lutnick suggesting that a total investment of $400 billion be proposed in the expectation that Trump would ask for $500 billion. A board was prepared by U.S. officials to clearly show Trump how much Japan would investment. But Trump demanded even more, leaving Akazawa no choice but to agree to $550 billion. A senior official of the prime minister's office acknowledged that the deal does not align with World Trade Organization rules or the Japan-U.S. trade agreement that took effect in January 2020, but also conceded that Trump "is a president who genuinely believes in protecting his country through tariffs."
