Japanese warships join with carrier Vinson on exercises

Defense News – Two Japanese destroyers joined up with the Carl Vinson carrier strike group in the Philippine Sea Sunday for renewed bilateral exercises, the Japan-based U.S. Seventh Fleet announced. The Vinson is headed north for the Sea of Japan in an expression of U.S. resolve as North Korea continues to develop offensive ballistic missiles with nuclear capability.

Islands on the frontline of a new global flashpoint: China v Japan

The Guardian – Ishigaki Island does not look like a frontline. Japan’s own tropical idyll, it is a sleepy place of pineapple fields and mango orchards, where thousands of tourists potter along white sand beaches and scuba dive in crystal clear seas. Yet this tiny dot on the edge of the Pacific is the closest Japanese town to the uninhabited but fiercely disputed Senkaku Islands, once inhospitable home to a tuna processing factory, now abandoned but key to lucrative fishing grounds, oil and gas fields and a strategic shipping route.

Tomahawk Missile for Japan

USNI News – Japan still lacks a key element of military power relevant for emerging challenges in the region—a flexible, long range strike weapon. The Tomahawk missile has long been a centerpiece of the U.S. military’s long-range precision strike portfolio. A sea-based weapon with a 1,000-mile range and a 1,000-pound warhead, it brings a proven proficiency for attacking well-defended, high-value land targets. New upgrades, including the ability to hit a ship, ensure the missile’s operational relevance beyond the next decade. The precedent for providing Tomahawk to allies was established nearly 20 years ago when the United Kingdom acquired 65 missiles. It is time to expand the “user club” to include Japan.

Japan’s Izumi-Class Helicopter Destroyer – An Aircraft Carrier in Disguise?

CIMSEC – To increase the potency of the JMSDF even further, the acquisition of aircraft carriers (CVs) would be a logical next step. Yet, as CVs can best be described as seagoing airbases with significant offensive capabilities, Japan’s pacifist constitution prohibits their use in its navy. Destroyers (DDs) on the other hand rely on speed and maneuverability and are easily employed in defensive roles, criteria deemed acceptable under the Japanese Constitution. Therefore, to accommodate this unique political limitation, the Japanese have designated one of their latest vessels as a “helicopter destroyer” (DDH) but with capabilities akin to those of an aircraft carrier.

Japan’s Signals Intelligence (SIGINT) Ground Stations: A Visual Guide

NAPSNet – This is a study of Japan’s ground-based signals intelligence (SIGINT) stations, the 17 (soon to be 19) major facilities that intercept, monitor, collect, process and analyse foreign electronic signals. Official statements convey nothing of the scale or detail of the Japanese SIGINT effort, which is probably the third or fourth largest SIGINT establishment in the world. These Japanese ground signals interception and location facilities are integrated with its air and missile defence radar facilities. Together with Japan’s own long-range underwater surveillance systems, and combined with the Japan-based US parallel air, ground and underwater surveillance systems, they take Japan a very long way towards its stated aim to ensure information supremacy in the region. As potentially lucrative targets in the event of war, destruction of these important but vulnerable facilities could alter escalation dynamics in such a way that the widespread assumption that a Japan-China armed conflict could be controlled before substantial escalation may not hold true.
