🌿 What is Setagaya City?

Setagaya sits just west of Shibuya and Shinjuku and is one of Tokyo’s largest residential districts.
Low-rise leafy neighborhoods stretch across the area, balanced by lively hubs such as Sangenjaya, Futako-Tamagawa, and Shimokitazawa.
Quiet streets and great convenience live side by side — a key reason for its enduring popularity.

Multiple private railway lines run through Setagaya, offering quick door-to-door access to major Tokyo stations.
With childcare facilities, schools, parks, and shopping areas all within walking distance, the district is highly favored by families, DINKS, expats, and remote workers.

📛 Origin of the Name

The name “Setagaya” is believed to come from an old place-name describing valley terrain in the area.
“Seta” is related to the word “Seta/Sedo” (a term describing a narrow strait or passage), and over time the pronunciation and writing evolved into today’s “Setagaya.”
The name reflects the geography and long-lived history of the region.
