The riverside edge of Den-en-chofu, where a park on the terrace above the Tamagawa River holds a row of ancient burial mounds
The closest neighborhoods in the same city.
Tamagawadai Park stretches about 600 meters along the Tamagawa River, with two large keyhole-shaped burial mounds and eight other kofun tombs inside, and about 3,000 hydrangeas bloom there in June. About a 5-minute walk north of Numabe Station, at the south end, is Sakurazaka, named after the cherry trees planted along both sides in 1930, with about 20 trees still lining the street today.
The park sits right around Tamagawa Station at the north end; the Kamenokoyama Kofun inside the park is 107 meters long and was designated a National Historic Site in 1928. On clear winter days, you can see Mt. Fuji straight ahead from the observation plaza.
This neighborhood covers Den-en-chofu 1-chome, Den-en-chofu Honmachi, and Den-en-chofu Minami, home to about 20,000 people as of 2020.
From our street photos, greenery ranks 131st out of 395 neighborhoods in Tokyo, near the top, and the highest-ranking category for this neighborhood. Public transit ranks 195th, in the middle of the pack.
Tamagawa Station at the north end is where the Toyoko Line, Meguro Line, and Tamagawa Line all meet. Numabe Station to the south has only the Tamagawa Line, with a ticket gate on each platform side, so you can't switch sides once you're inside.
The two stations are about 900 meters apart, connected by the three-car, all-stops Tamagawa Line.
Daily shopping ranks 334th out of 395 neighborhoods in Tokyo, toward the bottom; the area around Tamagawa Station is a low-rise residential area with no large stores nearby. Buildings rank 378th, the weakest category for this neighborhood.
TidyMap ran its own estimate, taking points roughly every 40 meters within the neighborhood on the Geospatial Information Authority of Japan's flood inundation hazard map. About 20% of the points fall within the projected flood zone, mostly 0.5 to 3 meters deep, with about 6% at 3 to 5 meters; the share is about 60% in Den-en-chofu Minami and about 10% in Honmachi and 1-chome. To check your specific address, use Ota City's hazard map.
This plateau along the Tamagawa River has had kofun tombs since early times: Kamenokoyama Kofun was built sometime between the late 4th and early 5th century. The main hall of Tamagawa Sengen Shrine stands atop another kofun; according to legend, during the Bunji era of the Kamakura period, Hojo Masako enshrined a statue of Kannon on this hill.
Tamagawa Station and Numabe Station both opened on the same day, March 11, 1923. In 1931, Tamagawa Station was renamed "Tamagawaen-mae," after the Tamagawaen amusement park next door.
Tamagawaen closed in 1979, and the site became Den-en-chofu Seseragi Park in 2006, where spring water welling up from the north and south at the base of the bluff forms a small stream.

Maps show the shops and the sights. What a street is like, you only know by walking it. TidyMap uses AI street imagery analysis and public facility data to turn each area's street environment and everyday convenience into something you can compare. Search an address and look at the street outside first.
How to read it: yellow = poor, blue = good; grey = not enough data
TidyMap rates the street environment and everyday convenience. It does not assess the home itself, safety, noise or actual living experience. Street environment scores use AI assessments of imagery; convenience scores use public facility data.
