Why is Japan abandoning its post-WWII pacifism?

Tensions with China and US unpredictability are factors

Japan wrote pacifism into its constitution and culture following World War II, but that era may be coming to an end. Prime Minister Sanae Takaichi last week moved to allow arms sales to foreign countries, signaling a pivot toward a more hawkish stance.

Many Japanese felt pride in the country’s postwar commitment to “never resort to force to settle international disputes,” said The Wall Street Journal. Pacifism “has been our moral compass after the tragedy,” 87-year-old Michiko Yagi said to the outlet. But growing tensions with China have sharpened a sense of alarm and increased support for Takaichi’s efforts to build the country’s defenses. Japan cannot expect the U.S. to come to its defense “when our own people aren’t even defending our own country,” said Nagasaki resident Masashi Kajiyama.

The U.S. focus on Iran is a factor in the pivot: The Trump administration moved military assets from Asia to the Middle East to support the war, leaving Japanese leaders “rushing to find viable alternatives for its own security and defense,” Keio University’s Michito Tsuruoka said to The New York Times. Raising Japan’s defenses is a response to an “increasingly challenging security environment,” Takaichi said in a social media post.

What did the commentators say?

Japan’s pacifism “once served a purpose,” Kenji Yoshida said at Asia Times. Dovishness “reassured neighbors” threatened by the country’s former militarism and enabled a near-miraculous economic recovery from World War II. But such stances “can outlive their usefulness.” Tokyo has long found ways to stretch its supposed constitutional limits, dispatching minesweepers during the 1991 Gulf War and deploying “non-combat” troops to Iraq during the 2004 invasion. “Public opinion remains cautious” on such issues, but the time has come for Japan to shed its “unsustainable pacifist illusion.”

The Japanese public is “divided” on the move to a more hawkish stance, The Japan Times said in an editorial. Japanese people retain an “instinctive concern” about security issues that is a “remnant of the bitter experience of World War II.” But an “increasingly contested security environment” in Asia requires change. Tokyo must “value hard power as a contributor to deterrence” against threats. “Ideally, the provision of defense equipment will prevent conflict, not enable it.”

What next?

Japan has seen a “seeming erosion of pacifist norms” over the past decade, said The Diplomat. Mass protests greeted 2015 legislation to allow the country’s military to deploy overseas. But Takaichi’s recent popularity suggests the arrival of a “post-pacifist” era, giving her “unprecedented authority to expand Japan’s defense ambitions.”

Takaichi has suggested she will seek “changes to the pacifist clause” of Japan’s constitution, said The Washington Post. But the hints of change have also sparked “rare nationwide protests” by Japanese who fear the country might be “drawn into military conflicts if it drops its constitutional guardrails.” The “hollowing out of pacifism” could prompt a backlash from Japan’s neighbors, Hiroshima City University’s Shiro Sato said to the Post, making Japan less safe by “increasing insecurity and potentially worsening the security environment.”
