Where the name Sangenjaya comes from, what stood here before the station, and what you can still spot on a walk today. Then the events near the station that we have checked on the official pages.
Sangenjaya means Three Teahouses, and the name comes from three roadside establishments known as Shigaraki, Kadoya, and Tanakaya. During the Edo period, pilgrims traveled from Edo toward Mount Oyama in present-day Kanagawa Prefecture to worship at Oyama Afuri Shrine. This area was a convenient place to stop before continuing west.
Stand near the junction of Route 246 and Setagaya-dori. The roads divide here, much as the old Oyama pilgrimage routes once did. Setagaya-dori followed the main route, while the road corresponding to Route 246 offered a shortcut. Travelers could rest at the teahouses and decide which road to take. Around them stretched a farming landscape producing vegetables for the growing city of Edo.
The introduction of electric railways transformed the crossroads. The Tamagawa Electric Railway opened in 1907, using Sangenjaya as a station name. The Shimotakaido branch, now the Tokyu Setagaya Line, opened in 1925. A place where travelers once chose between roads became an interchange for railway passengers. In 1932, Sangenjaya became an official neighborhood name. Three modest roadside businesses had given their name to an entire urban district.
→ Visit the junction of Route 246 and Setagaya-dori near Sangenjaya Station. Beneath the elevated expressway, you can still see where pilgrims once chose between the main Oyama road and its shortcut.

Sangenjaya's crowded restaurant alleys stand on a landscape shaped first by agriculture, then railways, and finally postwar urban growth. During the Edo period, fields spread along the roads now known as Route 246 and Setagaya-dori. Farther north toward Taishido, the low ground beside the Karasuyama River supported rice cultivation, with irrigation channels supplying the paddies. Much of that watercourse is now concealed beneath a greenway.
The Tamagawa Electric Railway opened in 1907 and helped turn the old highway junction into a commercial center. After the Great Kanto Earthquake of 1923, residents displaced from central Tokyo moved into the area. Fields became housing and shopping streets. A commercial map from 1932 already shows numerous shops around the district now called the Triangle.
After World War II, population growth accelerated. Small wooden houses and shops multiplied before roads could be properly improved, creating a dense network of narrow lanes. Enter the Triangle between Route 246 and Setagaya-dori to experience that compact streetscape. Then walk north along Chazawa-dori toward the Karasuyama River Greenway. The short journey connects the modern nightlife district with the agricultural valley that once lay behind the main road.
→ Explore the narrow lanes of Sangenjaya's Triangle, then follow Chazawa-dori north toward the Karasuyama River Greenway. Look for traces of former bridges along the covered river, once used to irrigate local rice fields.
