For several years now, Japan has been evolving in a strategic environment that no longer resembles that of the postwar era. The illusion of a stable regional order has given way to a far more volatile reality, marked by China’s military rise, the multiplication of tensions in the South China Sea, and an increasingly assertive willingness to challenge existing balances. China is now the world’s second-largest power, and the days when Tokyo held that position before the crises of the 1990s are long gone. In this context, the overhaul of Japan’s system governing the overseas transfer of defense equipment is not a sign of militaristic drift. On the contrary, it reflects a clear-eyed adaptation to a world in which power has once again become a central language.
It is time to stop misdiagnosing the situation. Since the end of the Second World War, Japan has established itself as one of the most pacifist powers in the world. Its Constitution, its participation in peacekeeping operations, its role in development aid, and its consistent commitment to multilateralism all reflect a deeply defensive strategic culture. To accuse Tokyo today of “remilitarization” and to raise the specter of a Japanese threat in the Pacific makes little sense.
This narrative, in fact, is largely driven by Beijing. China denounces a rearming Japan while itself pursuing a military expansion of unprecedented scale. The steady increase in its defense budget, the rapid development of its naval and air capabilities, and its massive arms exports worldwide all point to a reality far removed from its official discourse. The contrast is striking: on one side, a Japan that strictly regulates its transfers of military technology in accordance with international law and the Charter of the United Nations; on the other, a China acting ever more assertively to impose its views within its regional environment.
The issue of the Senkaku Islands perfectly illustrates this dynamic. These territories, administered by Japan, are regularly the target of Chinese maritime and aerial incursions as part of a strategy of constant pressure. Such actions go beyond mere diplomatic contestation; they reflect a gradual effort to alter the status quo. In this context, asking Japan to remain passive would be tantamount to asking it to renounce its own security.
The reforms undertaken by Tokyo are a direct response to these developments. By expanding opportunities for defense cooperation with its allies and partners, Japan is not seeking to project offensive power but rather to strengthen a network of collective security. The objective is clear: to build resilient value chains, share technological capabilities, and ensure greater interoperability with democracies in the region and beyond. In doing so, Japan is embracing a logic of deterrence, not confrontation.
