Japan has taken a major step in reinforcing its defense strategy by purchasing 400 Tomahawk cruise missiles from the United States. The deal, valued at $1.7 billion (approximately 254 billion yen), marks a significant investment in Japan’s defense capabilities. Produced by Raytheon, these missiles are scheduled for delivery by 2027, further enhancing Japan’s long-range strike options.

This procurement comes amid growing regional security challenges, particularly China’s expanding military power and North Korea’s nuclear arsenal. To counter these threats, Tokyo has committed to increasing its defense budget to 2% of GDP. The U.S. State Department had approved the sale in November 2023 under the Foreign Military Sales program, paving the way for this strategic acquisition.

The integration of Tomahawk missiles will substantially strengthen the Japan Maritime Self-Defense Force (JMSDF). The missiles are planned to be deployed on Kongo, Atago, Maya, and ASEV-class destroyers equipped with the Aegis system. The Block IV variant offers advanced capabilities, including retargeting in flight and the ability to transmit battlefield imagery, making them a versatile tool for precision strikes.

Raytheon is also modernizing existing Tomahawk Block IV missiles, extending their service life by an additional 15 years while improving range and targeting functions. With this upgrade, Japan will not only acquire new missiles but also secure a long-term, sustainable defense capability. Following the United Kingdom and Australia, Japan now joins the circle of international Tomahawk operators, reflecting the strengthening of U.S.-allied defense networks in the Indo-Pacific.
