Gamagori City - Aichi Prefecture’s Largest Hot Spring Town

Japan’s cities feature varied climates that make each of them a more suitable place to visit than the other at certain times of the year. The spring season is ideal for cherry blossom viewing at Matsumae Park, Hokkaido, the summer season is ideal for swimming and relaxing in Okinawa, the autumn season is ideal for strolling around the Eikando Temple grounds in Kyoto, and the winter season is ideal for skiing in Sapporo.

Planning the perfect Japan trip takes a lot of effort and is far more challenging for those traveling in groups. Aiming to complete each person’s list of places to visit and things to do in Japan is virtually impossible to accomplish in just one trip.

Fortunately, Japan has several cities that offer a little bit of everything the country has to offer; the Gamagori City of the Aichi Prefecture being one of the best.

The City of Gamagori (Gamagori-shi) in Aichi, Japan

Gamagori City, or Gamagori-shi, is considered to be the largest onsen (hot spring) resort area of the Aichi Prefecture, situated in the southeast section of Mikawa Bay’s coast. It has an estimated total area of 57 sq. km. and is inhabited by about 82,000 people. The surrounding municipalities of Gamagori City include Nishio, Kota, Toyokawa, and Okazaki.

During the Heian Period, Gamagori consisted of several shoen (autonomous manors or estates) that were subject to the Udono clan’s control. By the Edo Period, most of it fell under the rule of the Tokugawa shogunate thanks to hatamoto administrations, which consisted of samurai warriors directly serving the Tokugawa shogunate.

The area was designated as a village of the Hoi District during the early years of the Meiji Period, particularly on October 1, 1889. It was given an elevated status of being a town on October 6, 1891, and later expanded to include nearby villages such as Shizusato, Toyooka, and Kaminogo in 1906.

After merging with the Shiotsu Village and Miya Town, Gamagori was finally proclaimed as a city on April 1, 1954. It continues to expand until the year 1963 to include Otsuka (1956), Katahara (1962), and Nishiura (1963).

The city is known for being a regional fishing port and commercial center of agriculture and light manufacturing. It houses the Aichi University of Technology and several other schools. Some of the city’s areas are included in the Mikawa Wan Quasi-National Park.

Gamagori has four hot spring areas that go by the names Nishiura Onsen, Katahara Onsen, Gamagori Onsen, and Miya Onsen. These onsens and many other places within the city attract hundreds and thousands of visitors every year.
