Usage
Less common in traditional Japanese residential architecture than in Western countries, but found in modern buildings. 地下 alone can mean "underground" or "basement level" (as in 地下1階, basement floor 1), while 地下室 specifically means a room below ground.
Common collocations
- 地下室に降りる: to go down to the basement
- 地下室に保管する: to store in the basement
