Tokyo Metropolis (Shinjuku City 4). (Schoolgirls' Uniforms of Japan.)
These were uniforms for schoolgirls of one obsolete junior high school far from east-southeast of Takadanobaba Station, Metro Tozai Line, Tokyo Metro Subways, in Shinjuku City, Tokyo Metropolis.
The school was merged with another junior high school in 2005, and the unifroms were also changed then, so you can no longer see them.

The summer cloth was a white blouse with round collars, a red string tie, and a navy blue skirt.
About the Winter Uniform.
On the other hand, the winter one was a navy blue sailor blouse with three red stripes on its navy blue collars and a red tie.
