Earth Day

What Earth Day does

Earth Day Tokyo (アースデイ東京) is a Tokyo-based nonprofit organized as a General Incorporated Association (一般社団法人アースデイ東京), founded in 2001 to operate Japan's flagship annual Earth Day festival at Yoyogi Park. It is the Japanese chapter of the global Earth Day movement, which the UN formally designated as International Mother Earth Day in 2009 and which now spans approximately 175 countries and 500 million participants worldwide. Earth Day Tokyo has run continuous annual festivals for 25 years and is supported by a small secretariat led by Secretary-General Kono Ryuji (河野竜二, in role since 2018), with operational capacity drawn primarily from an estimated 500+ volunteers per event. The 2025 festival drew 80,000 visitors across two days, featuring 200+ exhibitor booths spanning NPOs, NGOs, companies, students, eco/fair-trade retailers, and food vendors.

The organization operates a hybrid event-and-program model built around a central annual festival, plus satellite activations including the Earth Day Global Summit (COP-aligned online/in-person programming), an Earth Day Summer Challenge with beach plogging in Shonan, Peace Day events (notably the Love & Peace Parade co-organized with Nihon Hidankyo following its 2024 Nobel Peace Prize), and a national Earth Day Japan Network coordinating regional events across Hokkaido, Chiba, Shonan, Toyama, Ishikawa, Nagano, Osaka, Okinawa, and Kyoto. Recent additions include the Inclusive Playground (co-developed with Inclusive Forest, launched 2026), the GX Youth Lab decarbonization-education program, and a recurring crowdfunding appeal. The organization's technology footprint is conventional digital (website, email, SNS) plus physical sustainability infrastructure (BDF generators from used cooking oil, PET cap oilification, solar power, reusable dish systems); no proprietary software or AI components are involved.

Earth Day Tokyo's revenue model blends corporate sponsorship (primary stream; tiers include special co-sponsor, co-sponsor, and supporter), transactional booth fees (NGO/NPO at JPY 32,400-54,000 and food vendors at JPY 108,000-172,800), crowdfunding and donations, and membership fees. Festival attendance is free for the general public, and the customer base spans four primary segments: NPOs/NGOs exhibiting their causes, sustainability-aligned corporate sponsors, youth/student activists (organized through the Earth Day Tokyo Youth wing and NEO Award), and eco-conscious food vendors operating within the Earth Kitchen. The 2026 edition marks the 25th anniversary under the theme "Spring Earth Culture Festival," while the 2025 edition focused on "Peaceful Change."
