Ota City: SUBARU's Hometown and Modern Manufacturing

Aviation technology that produced famous aircraft was eventually handed down to famous cars - Ota City in Gunma is a "manufacturing town" known as the birthplace of the automaker SUBARU. Before the war it was a major base of Nakajima Aircraft, which sent many renowned aircraft into the world, and that advanced technology was passed steadily on to the postwar automobile industry. It is a town of technology and history where you can experience the path of Japan's modern industry.

From Nakajima Aircraft to SUBARU

Ota was the home base of Nakajima Aircraft, one of prewar Japan's leading aircraft makers. It manufactured superb aero engines and fighters and boasted advanced technical prowess. After the war, Nakajima Aircraft became Fuji Heavy Industries (now SUBARU) by way of Fuji Sangyo, applying its cultivated aviation technology to carmaking and producing distinctive vehicles. Ota is truly the hometown of SUBARU.

The Manufacturing Cityscape

Ota is home to SUBARU's large-scale factory complexes, and the whole town conveys a history of developing alongside the auto industry. The company's visitor center offers exhibits where you can learn about its legendary cars, the path of its technology, and its dedication to craftsmanship, a spot car lovers cannot resist. Factory tour content and reception procedures can change by season, so checking official information before visiting is reassuring.

Highlights and Ota's History

Beyond its industrial face, Ota has historical and cultural highlights. Known as a place linked to Nitta Yoshisada, the Kanayama Castle ruins on Mount Kanayama - with a commanding view of the Kanto Plain - retain splendid stone walls and stone-paved remains and are a nationally designated historic site. Highly regarded nationwide as a medieval mountain castle, it is also selected among Japan's 100 Famous Castles. It is a town where you can enjoy the appeal of both manufacturing and history.

Seasonal Fun

It can be enjoyed year-round, but hiking the Kanayama Castle ruins is especially recommended in the fresh-green and autumn-foliage seasons. From near the summit a grand panorama of the Kanto Plain opens up, changing its expression with each season. In the city, savoring local fare such as the specialty "Ota Yakisoba" is one of the trip's pleasures.

Access and Essentials

The base is "Ota Station" on the Tobu Isesaki Line. From the Tokyo area, limited express or express trains take around an hour and a half as a guide. By car, the "Ota-Kiryu IC" and "Ota-Yabuzuka IC" on the Kita-Kanto Expressway are convenient, and each facility has parking. For the Kanayama Castle ruins, head from Ota Station by car or taxi and walk the trail from the midway parking lot, which is the usual approach.
