Tokyo Rainbow Pride, the nation's largest festival for lesbian, gay, bisexual and transgender (LGBT) communities, will have its third annual parade in Tokyo on Sunday, aiming to raise awareness of sexual minorities in Japan.

The parade is scheduled to proceed from Shibuya Station to the Harajuku district in the afternoon, while numerous citizens groups, businesses and foreign embassies will open booths in Yoyogi Park.

"We had 12,000 visitors in last year's Pride," said Shinya Yamagata, 47, a freelance editor and chief representative of the event, "but we are expecting to have 20,000 visitors for this year, as the number of parade floats has increased from nine to 15."
