Tokyo Rainbow Pride takes place on Sunday, April 27 in Harajuku’s Yoyogi Park. It’s part of Tokyo’s Rainbow Week, which runs from April 26th to May 6th.
Regarding TRP’s awesome mascot, from the great blog Tokyo Moe:
The mascot is a flying squirrel that lives in Shinjuku named Tobe. The name combines the Japanese word “fly” (飛ぶ) and the English word “to be” signifying personal expression.
