WARNING! Imminent Hypersonic Threat!

Japan’s 2025 Defense White Paper warns that North Korea’s bolstered development of hypersonic missiles constitutes a “grave and imminent threat,” prompting plans for advanced interceptor systems to fortify its homeland defenses.

At a Glance

• Published on 16 July 2025, Japan’s annual defense report identifies North Korea’s hypersonic missile advancements as a major regional danger.
• The Defense Ministry describes these weapons as faster than current tracking and interception capabilities.
• Tokyo plans to invest in new interceptors, including hypersonic-capable missiles and glide-phase defense systems.
• The paper also cites North Korea’s deepening military cooperation with Russia and China.
• This is the first time hypersonic threats have been labeled “grave and imminent” in a Japanese defense policy document.

A Sharp Warning From Tokyo

The White Paper outlines that North Korea’s rapidly evolving hypersonic missile program, including variants like the Hwasong-16B, presents an unparalleled challenge to Japan’s security. These solid-fuel hypersonic weapons can maneuver unpredictably at speeds exceeding Mach 5, complicating detection and interception. Japanese officials also warned of Pyongyang’s expanding collaboration with Russia on missile technology and testing data, further destabilizing regional security dynamics.

Preparing For Hypersonic Defense

In direct response, Japan is expediting the deployment of advanced interceptor systems capable of targeting missiles during their glide phase. These include next-generation glide-phase interceptors designed to neutralize hypersonic threats before they reach terminal velocity. Enhanced radar networks and integrated missile defense strategies with the United States and South Korea form part of Tokyo’s strategic blueprint to safeguard the nation against emerging threats.
