Despite defense buildup, Japan's arms industry struggles

ENIWA, Japan (AP) — The dozens of Type 90, or “Kyumaru,” tanks rumbling through recent shooting drills on Japan's northern island of Hokkaido exemplify the challenge its arms makers face both at home and overseas as the country fortifies its defenses against strategic threats.

The Self Defense Force needs the more advanced aircraft and weaponry sold by U.S. arms manufacturers as Japan’s strategic focus shifts from Russia in the north to the south, where it faces incursions by Chinese fighter jets and naval vessels and North Korean missile launches.

Big Japanese defense manufacturers like Mitsubishi, IHI Corp. and Kawasaki Heavy Industries are struggling to sell 20th century tanks, aircraft and warships. They need to develop better technology to serve a military in the market for unmanned aircraft like Tritons made by Northrop Grumman and Boeing’s undersea Echo Voyager.

Likewise, Japan's international arms sales never really have taken off. Uncompetitive, with high prices, aging technology and scant government support, arms makers in Japan increasingly are just withdrawing from the business.

The hefty Kyumaru tanks built by Mitsubishi Heavy Industries debuted 30 years ago and are being replaced with lighter and more mobile armored vehicles that can travel on public roads and or have amphibious capabilities, including American amphibious assault vehicles.

“People may think Japan has advanced technology and it can quickly catch up with others and start selling equipment if it only gets serious, but I think that’s wrong,” said Heigo Sato, an expert on defense issues and professor at Hokkaido's Takushoku University.

“The problem is, Japan’s defense products are not first grade. Nobody is interested in buying second- or third-grade products at higher prices,” he said.
