There's a difference between not addressing the past, and actively considering retracting official apologies and statements on the matter, and starting a trade war over it. https://foreignpolicy.com/2020/09/04/shinzo-abe-japan-south-...

> Abe’s revisionism is not exactly a secret. He has expressed admiration for his grandfather Nobusuke Kishi, who was imprisoned after World War II on the charges of being a Class A war criminal. Abe was a special advisor to the group Nippon Kaigi (Japan Conference), which claims Imperial Japan should be lauded for liberating Asia from Western colonial powers, the Tokyo war crimes tribunals were illegitimate, and war crimes such as the Rape of Nanking in 1937 were exaggerated or fabricated. (In 2014, 15 out of 18 cabinet members in the Abe administration were Nippon Kaigi members.)

> In 2007, during his brief first stint as prime minister, Abe personally disavowed the 1993 Kono Statement that apologized to the World War II-era victims of systematic sexual abuse by the Japanese army, dishonestly claiming a lack of evidence. When Kan made the centennial speech accepting responsibility for Imperial Japan’s annexation of Korea, Abe yelled, “Idiot!” at Kan on live television. Upon taking office again in 2012, Abe wasted no time in showing the world where he stood on the history issues: He openly flirted with officially retracting the 1993 apology to the so-called comfort women and visited the controversial Yasukuni Shrine, which enshrines Japan’s war criminals, over strong criticisms from both South Korea and the United States.

> All of this drove South Korea-Japan relations to the brink, and then Abe’s most egregious misstep marched the relationship off the cliff.All of this drove South Korea-Japan relations to the brink, and then Abe’s most egregious misstep marched the relationship off the cliff. In order to settle the historical score, he weaponized the two countries’ trade relationship. In October 2018, South Korea’s Supreme Court issued the long-delayed opinion that Japanese corporations that used slave labor from Korea during World War II must pay reparations to surviving slave laborers. (The delay was in part because since 2013, Japan’s foreign ministry had been issuing barely disguised threats for the South Korean government to “respond appropriately” to the pending case, and the quasi-authoritarian Park Geun-hye government acquiesced and pressured the Supreme Court to delay the ruling in contravention of the most basic principles of separation of powers.)

> In response to the court’s opinion—which ordered the reparation of $89,000, a negligible amount for Japan’s largest corporations—Abe declared a trade war. The Abe administration announced export control against South Korea for three critical chemicals used in high-end display and semiconductor manufacturing, immediately after the G-20 summit in Osaka, Japan, in which the prime minister called for a free and fair trade. When confronted with the criticism that Japan was using trade for political purposes, Chief Cabinet Secretary Yoshihide Suga (the front-runner to be the next prime minister) vaguely cited national security concerns as the reason for the export control, even as he dangled the idea that South Korea “did not offer a satisfactory solution over the issue of former workers.” So flimsy was the justification that some experts observing the issue noted that Japanese officials “haven’t provided any evidence” and “have not named companies or said how supplies may have been mismanaged.” Others went further, calling Tokyo’s excuse “duplicitous” and saying it was behaving “spuriously.”
