Processing: boundaries that reach into Tokyo Bay clipped to the coastline,
geometry simplified for display with a tolerance of 0.0002 degrees, islets
under about 0.02 km² dropped and coordinates rounded to six decimals. IDs
01-23 and s01-s08 are assigned for this map; they are not official codes.

The map shows all 23 special wards: Chiyoda, Chuo, Minato, Shinjuku, Bunkyo,
Taito, Sumida, Koto, Shinagawa, Meguro, Ota, Setagaya, Shibuya, Nakano,
Suginami, Toshima, Kita, Arakawa, Itabashi, Nerima, Adachi, Katsushika and
Edogawa. A second round adds seven Tama cities, Musashino, Mitaka, Chofu,
Komae, Nishitokyo, Koganei and Fuchu, and Urayasu in Chiba Prefecture. The
map is for geographic learning, not navigation or legal boundaries.

Sight coordinates were checked against OpenStreetMap features, with pins
representing locations rather than guaranteed entrances.
