Gunma is an inland prefecture ringed by mountains — Akagi, Haruna, and Myogi — that has decided to lean fully into what it is: hot springs, mountains, silk history, and a self-aware regional pride that has produced one of Japan's most beloved internet meme cultures (Gunma is repeatedly depicted in Japanese internet culture as a mysterious, barely accessible parallel Japan, which the prefecture has gamely embraced). The hot spring town of Kusatsu is the most quantitatively impressive in Japan: it produces 32,300 litres of hot water per minute, making it the highest-flow spa in the country. The water is highly acidic (pH around 2), historically used for skin conditions, and the yumomi tradition — large wooden paddles used to cool the water to batheable temperatures while crowds watch — is performed several times daily.
Getting There
Gunma has no Shinkansen of its own (the Joestu and Hokuriku Shinkansen pass through en route to Niigata and Kanazawa but serve Takasaki and Jomo-Kogen rather than the interior). Takasaki is 50 minutes from Tokyo on the Shinkansen, making it the most practical base. The prefecture is fundamentally car-oriented outside the Takasaki-Maebashi urban zone, and driving through the mountain roads — particularly to Kusatsu, up toward the Shiga Kogen plateau, or along the Tone River gorge — is part of the experience.
Daily Life
The Tomioka Silk Mill, a UNESCO World Heritage Site, tells the story of Gunma's 19th-century identity as the engine room of Japan's silk industry — the first government-operated modern mill, which used French machinery and French instructors to jumpstart Japan's industrialisation. Silk culture is still visible in the regional crafts and textiles. Gunma's mountains are popular skiing and snowboarding destinations in winter (Shiga Kogen, shared with Nagano, is one of Japan's largest ski areas). Maebashi and Kiryu in the lowland basin are industrial and commercial towns with their own character; Kiryu in particular has a weaving heritage that produced some of Japan's finest fabrics.
Festivals & Culture
Local festivals include the Takasaki Daruma Matsuri — the daruma doll (a round, weighted good-luck figure) is closely associated with Gunma, and Takasaki is the country's biggest producer of them. The food culture is strong on soba, udon, and agricultural produce from the upland farms. The character of Gunma people is straightforward and unpretentious.
Buying Property Here
Property buyers find Gunma affordable and well-positioned relative to Tokyo. Maebashi and Takasaki houses run ¥5M–¥15M. The mountain resort towns — Kusatsu, Minakami — have a mix of resort properties and older local houses from ¥3M–¥15M depending on proximity to skiing and hot springs. Rural agricultural akiya in the basin towns start from ¥500,000–¥3M. Gunma is for buyers who want mountains, hot springs, reasonable Tokyo access (1–2 hours), and prices that reflect the prefecture's deliberately low profile.
