The Romantic Legend Behind the Name Tsumagoi
The name Tsumagoi is associated with a famous legend about Yamato Takeru-no-Mikoto, a legendary hero of ancient Japan.
According to tradition, Yamato Takeru lost his beloved wife, Ototachibana-hime, during his eastern expedition. On his journey home, he looked out over a sea of clouds from Torii Pass and cried out, “Azuma wa haya”, expressing his grief for his wife. This story is said to be connected to the origins of the names Agatsuma and Tsumagoi.
The romantic theme of a man longing for his beloved wife remains an important part of Tsumagoi’s identity. Today, the village is known as a “Sacred Place for Loving Couples”, and attractions such as Ai no Oka (Hill of Love) celebrate family bonds, marriage, and affection.
Mountains, Rivers, and Highland Landscapes
Tsumagoi lies within the Joshin’etsukogen National Park and is surrounded by impressive peaks such as Mount Asama, Mount Azumaya, Mount Motoshirane, and Mount Kusatsu-Shirane.
The Agatsuma River flows from west to east through the center of the village, and many settlements and agricultural areas developed along its valley.
The village is also home to several lakes, including Tashiro Lake and Lake Baragi. At Lake Baragi, Mount Azumaya can be reflected beautifully on the surface of the water, creating one of the area’s most picturesque landscapes.
The volcanic soils found across the highlands are particularly suitable for agriculture. These soils, combined with the cool climate and large temperature differences between day and night, have helped make Tsumagoi one of Japan’s leading highland farming areas.
A Cool Highland Climate
Tsumagoi has a cool mountain climate, with an average annual temperature of around 7.4°C. Summers are generally mild, with very few extremely hot days, while the difference between daytime and nighttime temperatures can be considerable.
This dramatic temperature difference is one of the factors that helps produce the area’s famously sweet and crisp vegetables.
Winter is much colder, with frequent subzero temperatures and heavy snowfall. Temperatures can occasionally fall below -15°C. While these conditions create a harsh winter environment, they also make Tsumagoi attractive for skiing, snow activities, and winter scenery.
A History Shaped by Volcanoes
The history of Tsumagoi dates back to the Jomon Period of prehistoric Japan. Numerous pieces of Jomon pottery and stone tools have been discovered in the area, suggesting that the region was an important meeting point between cultures from central Japan and the Kanto region.
In 1108, Mount Asama experienced a major eruption that covered the surrounding area with volcanic ash. An even more devastating eruption occurred in 1783, during the Edo period. The village of Kamahara suffered catastrophic damage, and many people lost their lives.
The stone steps of Kambara Kannon-do Temple were buried by the eruption and remain today as a powerful reminder of the disaster.
Despite the devastation, local residents rebuilt their lives and communities. Families were reunited and neighbors supported one another during the difficult years that followed. The history of living alongside volcanic forces can still be experienced at places such as Onioshidashi Park and the Asama Lava Tree Molds.
Japan’s Leading Summer-Autumn Cabbage-Producing Region
Agriculture is one of the foundations of Tsumagoi’s economy. The village is particularly famous for its summer-autumn cabbage, for which it is known as Japan’s leading production area.
Grown at elevations of more than 700 meters, Tsumagoi cabbage benefits from the cool climate and large differences between daytime and nighttime temperatures. These conditions help create cabbage that is crisp, juicy, and naturally sweet.
From June through November, enormous cabbage fields spread across the highlands, creating scenery that resembles a vast green carpet.
Other local specialties include hanamame beans, corn, and potatoes. Hanamame are particularly large beans prized as a premium agricultural product, while locally grown corn is famous for its exceptional sweetness and can even be eaten fresh.
Hot Springs of Manza, Kazawa, and Asama Highlands
Tsumagoi is also known for its diverse hot spring resorts. Major areas include Manza Onsen, Kazawa Onsen, Baragi Onsen, and Tsumagoi Onsen.
