A Landscape of Mountains and Rivers
From 470 Meters to More Than 2,200 Meters
One of Tomi City’s defining characteristics is its dramatic difference in elevation. The highest point is Mt. Higashikagonoto at 2,228 meters, while the lowest point is approximately 470 meters in the Nishiumino area along the Chikuma River.
The city stretches approximately 14.7 kilometers from east to west and 16.5 kilometers from north to south. This wide range of elevations creates a remarkably diverse environment, from relatively warm agricultural areas to cool high mountain landscapes.
Mountain Scenery and Outdoor Activities
Several prominent mountains rise within and around Tomi City, including Mt. Eboshidake at 2,066 meters, Mt. Yunosumaruyama at 2,101 meters, Mt. Higashikagonoto at 2,228 meters, and Mt. Nishikagonoto at 2,212 meters.
These mountains provide opportunities for hiking, trekking, nature observation, and scenic drives. The landscape changes dramatically with the seasons, making the area attractive throughout much of the year.
The Chikuma River and Other Waterways
The Chikuma River, one of the major rivers of Nagano Prefecture, flows through the city, joined by smaller waterways such as the Hirasawa, Kanagawa, Sakurazawa, and Oishizawa rivers.
These clear streams have long supported both local communities and agriculture, providing water for fields and contributing to the fertile landscape of eastern Shinshu.
A Distinctive Mountain Climate
Cool Winters and Comfortable Highland Summers
Tomi City’s climate varies considerably with elevation. Winter can be particularly cold, and temperatures can fall as low as approximately 10 to 15°C below freezing on the coldest days.
In summer, the higher elevations remain pleasantly cool, particularly in the mornings and evenings, while the lower areas can feel considerably warmer during the daytime. This difference in climate allows visitors to experience very different landscapes within a relatively small area.
Annual precipitation is relatively low, at approximately 700 to 1,000 millimeters, and snowfall is generally modest compared with many other mountainous parts of Nagano. The combination of abundant sunshine, limited rainfall, and well-drained south-facing slopes has also helped create favorable conditions for agriculture.
Tomi City’s Agriculture and Local Specialties
Agriculture Shaped by Sunshine and Dry Conditions
Tomi City makes the most of its long hours of sunshine, low rainfall, and south-facing terrain. A wide variety of crops are grown across the city’s different elevations, making agriculture an important part of local culture and the regional economy.
Shinshu Walnuts
One of Tomi City’s best-known agricultural products is the walnut. The city is one of the major walnut-producing areas in Nagano Prefecture, with the Shinano walnut being particularly important.
Shinano walnuts have relatively thin shells that are easy to crack and contain a generous amount of nutmeat. Their rich flavor and convenient characteristics have made them a popular local specialty.
Grapes, Rice, and Potatoes
Kyoho grapes are another specialty. The region’s climate and soils help produce large, juicy grapes with a naturally sweet flavor.
Yaehara rice is grown in higher-elevation areas, where the cool climate helps produce rice with a distinctive, firm flavor. Shiratsuchi potatoes are also popular for their high starch content and satisfyingly fluffy texture when cooked.
A Productive Agricultural Region
The scale of agricultural production illustrates the richness of Tomi’s farmland. In 2017, major harvests included approximately 4,930 tons of rice, 682 tons of summer-autumn lettuce, 643 tons of summer Chinese cabbage, 558 tons of summer-autumn cabbage, and 297 tons of summer-autumn tomatoes.
For visitors, these agricultural products provide an opportunity to taste the character of Tomi through fresh local ingredients and regional foods.
Historic Kaido Streets at Unno-juku
A Preserved Edo-Period Post Town
Unno-juku is one of Tomi City’s most important historic attractions. The settlement flourished during the Edo period along the Hokkoku Kaido, a historic highway that connected inland areas with the Sea of Japan.
Much of the traditional streetscape has survived, with historic buildings lining the road and creating an evocative atmosphere. Walking through Unno-juku offers visitors a chance to imagine what travel through Japan looked like before modern railways and highways transformed the country.
The Hokkoku Kaido was selected as one of Japan’s 100 Famous Roads in 1986. In 1987, Unno-juku was designated as an Important Preservation District for Groups of Traditional Buildings, recognizing the cultural value of its historic townscape.
Yunomaru Highlands: Mountains and Flowers
A Highland Landscape for Every Season
The Yunomaru Highlands are a popular destination for hiking, mountain activities, and nature observation. The landscape changes beautifully throughout the year, while winter transforms the area into a ski resort.
Yunomaru Azalea Colony
One of the area’s most spectacular natural sights is the Yunomaru Azalea Colony, designated as a National Natural Monument. Around June, the slopes are covered in vivid red flowers, creating an impressive highland landscape.
The flowering season is one of the best times to visit, particularly for travelers interested in photography, hiking, and Japan’s seasonal flora.
Relaxing in Tomi’s Hot Springs
Hot Springs After a Day Outdoors
Tomi City is also home to several hot spring facilities, including Yurari-kan, Yufuru Tanaka, and Mimakino-yu. Many offer day-use bathing, making them convenient places to relax after hiking, sightseeing, or exploring the historic streets of the city.
Soaking in a Japanese hot spring while surrounded by the mountain landscape of Shinshu is an ideal way to slow down and enjoy the region at a more leisurely pace.
