Cottages were built to the lakeside and the Japanese Imperial Family, a Japanese aristocrat, etc. came to visit also. The yacht race was opened there, an airplane came flying for movement. There was a Western atmosphere there. Fishing was the most popular play among the visitors. It was British style trout fishing (fly-fishing), and was carried in for the first time in Japan. "Tokyo Angling and Country Club" was inaugurated to enjoy golf and fishing at Senju-ha-hama beach. The members of the club consisted of the leader of political and business circles, the diplomat in Japan, and the Imperial Family. As a resort in which a high-class person gathers, the outskirts of Lake Chuzenji was established its status. Although there was also time currently called "Ministry of Foreign Affairs of summer" in early stages of Showa from Taisho, the area was damaged by World War II. Only the chimney of a fireplace portion stands still at the lakeside now. Although it is lonely, there was the romance.

The name of Senjo-ga-hara originates in the "battlefield" which appears in the myth. The struggle occurred regarding territorial possessions of Lake Chuzenji. The battle was done by the God of Futarasan of Shimotsuke (former Tochigi prefecture) and the God of Mt. Akagi of Kouzuke (former Gunma prefecture). Shimotsuke and Kouzuke are the countries, which adjoin across Lake Chuzenji. This battle was by the large herd of snake on Futarasan side, and the large herd of centipede on Mt. Akagi. The Futarasan was inferior in strength at the first time, but the God of the Futarasan remembered the man, who might defeat troop of the Mt. Akagi. He was the expert of a bow called Sarumaru. The God of the Futarasan tried to lure Sarumaru out by changing his appearance to the white deer. Sarumaru chased the white deer and came to Futarasan as the white deer intended. The God of Futarasan asked Sarumaru to defeat the troop of Mt. Akagi. Sarumaru found two-horned giant centipede, which seems to be the enemy’s leader. Sarumaru hit the left eye of the enemy's leader, and defeated enemy of the Mt. Akagi finally.

Moreover, SHIRAKAMBA, which has a nickname as "Noblewoman of Odashiro-gahara”, is the popular target among the hiker and photographer.

Wild birds

Senjo-ga-hara is also well known for many kinds of wild bird. You will see them at the forest zone, and by walking along the "Senjo-ga-hara Natural Research Path". Those wild birds will multiply around May to July in Senjo-ga-hara.
