Sangenjaya (also known as Sancha) is an old Tokyo neighborhood close to downtown (7 minutes to Shibuya by train). It's a quiet but convenient area filled with appealing old shops.
Sangenjaya is in Setagaya — an affluent district of expensive homes. Over 800,000 people live in Setagaya making it Tokyo's most populated district. Setagaya's urban landscape is characterized by tiny (yet pricey) wooden homes built centimeters apart. (x)
