Earth Day Tokyo 2009, a two-day festival aimed at raising environmental awareness, will kick off at Yoyogi Park in Shibuya Ward and other venues Saturday.

The world's largest Earth Day festival is expected to attract 130,000 people to the park, where musicians will hold concerts, nonprofit organizations will exhibit their philanthropic activities and shops will have a range of organic foods on sale.

Participants at the ninth annual festival will promote ecological lifestyles and the development of electricity generated by fuels with low carbon dioxide emissions.
