Japan's Military Revival: How Washington Asked and Tokyo Finally Answered

On a clear morning in March 2026, this correspondent watched Japanese Self-Defense Force engineers break ground on Ishigaki Island, eight kilometers from the East China Sea. They were building what Tokyo calls a 'logistical facility.' The concrete foundations will support Type 12 surface-to-ship missiles with a range of 1,000 kilometers. That reaches the Taiwan Strait. Everyone on the island knows it. No one says it aloud.

The fishermen who used to moor their boats where the base now stands have been relocated. They received compensation. They do not complain publicly. One man, sixty-three years old, who asked not to be named, said what others would not: 'We are the trip wire now. If something happens with Taiwan, it starts here.'

Japan is remilitarizing. Not preparing to. Not considering. Doing it. After seventy-nine years of Article 9 pacifism, constitutional constraints that banned offensive weapons, and a defense budget capped at one percent of GDP, Tokyo has rewritten the rules. In December 2022, Prime Minister Fumio Kishida's government adopted three new security documents that reversed postwar doctrine. By 2027, Japan will spend 2 percent of GDP on defense — $320 billion over five years. It will acquire Tomahawk cruise missiles from the United States. It will deploy hypersonic weapons. It will build a network of missile bases across the Ryukyu Islands, the archipelago that runs from Kyushu to Taiwan.

This is not incremental drift. This is structural transformation. And it is happening because Tokyo has concluded that the alternative — relying entirely on American protection while China builds the world's largest navy and North Korea fires missiles over Japanese cities — is no longer tenable.

What Changed

The numbers tell the story that politicians avoid. In 2022, North Korea launched 37 ballistic missiles, including one that flew directly over Hokkaido on October 4, triggering evacuation alerts across northern Japan. In 2023, Pyongyang launched 31 more. In 2024, the number rose to 42. This year, as of April 12, there have been 18 launches. Japanese air defense systems track every one. They cannot intercept them all.

China's People's Liberation Army Navy now operates more than 370 warships, surpassing the United States Pacific Fleet in raw numbers. Chinese Coast Guard vessels routinely enter waters around the Senkaku Islands, which Japan administers and China claims as the Diaoyus. Between January 2023 and March 2026, Japanese Coast Guard records show 1,247 incursions into the contiguous zone and 89 into territorial waters. Tokyo protests each one. Beijing ignores the protests.

The Kishida government's December 2022 strategy documents — the National Security Strategy, National Defense Strategy, and Defense Buildup Program — formalized what had been creeping policy for years. They introduced the concept of 'counterstrike capability,' a euphemism for offensive strike weapons that can hit enemy missile launch sites before they fire. Article 9 of Japan's constitution, written by American occupiers in 1947, renounces war and prohibits maintaining 'land, sea, and air forces.' Tokyo has always interpreted this narrowly: the Self-Defense Forces are not 'forces,' and defensive weapons are permitted. Now the government argues that striking an enemy preparing to attack Japan is defensive. Legal scholars call it sophistry. The government calls it necessity.

The United States welcomed the shift. Washington has spent two decades urging Tokyo to shoulder more of its own defense burden. Under the 1960 U.S.-Japan Security Treaty, America is obligated to defend Japan. But the treaty was written for a different era, when Japan had no military and China was isolated. Today, Pentagon planners privately acknowledge they cannot fight a war with China over Taiwan without Japanese bases, Japanese logistics, and increasingly, Japanese firepower.

The Ryukyu Archipelago Becomes a Front Line

Ishigaki is the new reality. So is Yonaguni, Japan's westernmost inhabited island, 110 kilometers from Taiwan. The Self-Defense Forces opened a radar station there in 2016. In 2023, they expanded it into a full garrison with 700 personnel. In January 2026, they deployed Type 12 missiles. Miyako Island, midway along the chain, now hosts 800 troops and an air defense battery. Amami Oshima and Okinawa itself are being reinforced.

The plan is explicit: turn the Ryukyu Islands into a defensive barrier that can close the Miyako Strait and Bashi Channel, the waterways Chinese warships must transit to reach the Pacific. In a Taiwan conflict, these islands would not be rear positions. They would be contested ground from the first hour.

On Ishigaki, the fisherman who spoke to this correspondent lives in a house four kilometers from the new base. He has three children. All of them have moved to the main island of Okinawa or to Kyushu. 'They don't say it's because of the missiles,' he said. 'But I know.' His wife keeps emergency supplies in a closet: water, rice, batteries, iodine tablets in case of a nuclear incident. She checks the expiration dates every three months.

Okinawa, which hosts 70 percent of U.S. military facilities in Japan, has opposed the militarization for decades. Governor Denny Tamaki, elected in 2018 on an anti-base platform, has protested every new deployment. Tokyo overruled him every time. The central government invoked national security. The bases went forward. In February 2026, a poll by the Ryukyu Shimpo newspaper found that 68 percent of Okinawans opposed the missile deployments. The Ministry of Defense said the deployments were 'proceeding as planned.'

What the Generals Are Planning

In January 2026, Japan and the United States announced a new joint command structure, the most significant military integration since the Security Treaty was signed. U.S. Forces Japan, currently a coordinating headquarters, will be upgraded to a full joint task force with operational command authority. It will work directly with a newly created Japanese Joint Operations Command. In a crisis, American and Japanese forces will fight under unified planning.

Tokyo is also rebuilding its defense industrial base. For decades, Japan produced sophisticated components for American weapons but rarely exported finished systems. In 2023, the government lifted the ban on exporting lethal weapons to countries engaged in 'active conflict.' In December 2025, Japan sold Patriot missile interceptors to the United States, which transferred them to Ukraine. It was a legal and political breakthrough. Japan is now negotiating arms sales with the Philippines, which is also facing Chinese pressure in the South China Sea.

Mitsubishi Heavy Industries, Kawasaki Heavy Industries, and IHI Corporation are ramping up production of missiles, radar systems, and naval vessels. The government has committed $15 billion to expand munitions stockpiles, which defense analysts say were dangerously low. 'We could fight for maybe two weeks,' one retired Ground Self-Defense Force general told this correspondent in Tokyo. 'After that, we would run out of missiles, out of precision-guided munitions. The Americans would have to resupply us. That is not sovereignty.'

What Beijing Sees

China calls it militarism. Foreign Ministry spokesman Wang Wenbin said in March 2023 that Japan was 'walking down a dangerous path' and 'discarding the lessons of history.' The People's Daily, the Communist Party's official newspaper, published an editorial in January 2026 titled 'Tokyo's Remilitarization Threatens Regional Peace.' It accused Japan of using the North Korean threat as a pretext to build offensive capabilities aimed at China.

Beijing is not entirely wrong. Japanese defense planners do not hide the fact that their primary concern is China, not North Korea. Pyongyang's missiles are a threat, but they are a manageable one with missile defense and deterrence. A Chinese blockade of Taiwan, or a move to seize the Senkakus, is an existential scenario. It would sever Japan's sea lanes, which carry 99 percent of its energy imports. It would put Chinese forces within striking distance of Okinawa.

The security dilemma is playing out in real time. Japan arms because it fears China. China expands its military because it sees Japan, allied with the United States, as part of an effort to contain it. Both sides claim they are acting defensively. Both are creating the conditions for conflict.

What the Public Thinks

Japanese public opinion is divided, but shifting. A Yomiuri Shimbun poll in December 2025 found that 56 percent of respondents supported the government's plan to acquire counterstrike capabilities, up from 48 percent in 2022. Support was highest among voters over 60, the generation that remembers the Cold War. It was lowest among voters under 30.

Opposition parties and civil society groups have condemned the militarization. The Constitutional Democratic Party argues that counterstrike capabilities violate Article 9. The Japanese Communist Party calls it a return to prewar imperialism. Peace activists have held protests in Tokyo, Osaka, and Naha. The protests are small. Most Japanese are not marching in the streets. But they are not enthusiastic either. The prevailing mood is resigned pragmatism: We do not want this, but we see no alternative.

The Kishida government has done little to build public consensus. It announced the new defense strategy with minimal debate. It did not seek a referendum or hold extensive hearings. It relied on the Liberal Democratic Party's parliamentary majority and passed the necessary legislation. The process was efficient. It was not democratic in the sense that Gellhorn would recognize: not a conversation with the people who will live with the consequences, but a decision made for them.

What Happens Next

Japan is not going back. The Tomahawks are on order. The missile bases are being built. The budget has doubled. Even if a future government wanted to reverse course, the infrastructure is permanent. Okinawa will remain militarized. The Ryukyu chain will remain a front line.

The risks are obvious. An armed Japan increases the chances of miscalculation in a crisis. If Chinese ships approach the Senkakus and Japanese forces fire warning shots with new offensive capabilities, Beijing may interpret it as escalation. If North Korea launches another missile over Japan and Tokyo considers a counterstrike, Pyongyang may launch more. Deterrence works until it does not.

But the alternative — remaining passive while adversaries arm and threaten — is also a risk. Japan tried that approach for decades. It worked while America was unambiguously dominant and China was focused inward. That world no longer exists.

On Ishigaki, the construction continues. The fisherman walks past the site most mornings. He does not stop to watch. He knows what is being built. He knows what it means. 'My grandfather survived the war,' he said. 'He told me: Never again. But here we are.' He did not sound angry. He sounded tired. That is the mood across much of Japan. Not eager for conflict. Not preparing for glory. Just preparing.
