アースデイジャパンネットワーク

What アースデイジャパンネットワーク does

Earth Day Japan Network (アースデイジャパンネットワーク, EDJN) is a general incorporated association (一般社団法人) established on April 21, 2023, and the official Japanese affiliate of U.S.-based EARTHDAY.ORG. The organization functions as a coordination platform connecting approximately 30 local Earth Day organizing committees across all major Japanese regions (Hokkaido, Tohoku, Kanto, Chubu, Kinki, Chugoku/Shikoku, Kyushu/Okinawa). Its core products are: (i) the Earth Day Map, an interactive web directory using Google Maps and Google Calendar to register and browse Earth Day events nationwide, targeting 300 registered actions in 2026; (ii) monthly online Open Meetings (first Wednesday, 20:00-21:30) for organizer networking; and (iii) an annual Earth Day Forum held the first Saturday of April each year. Supporting offerings include translated content from EARTHDAY.ORG, an official Note blog, an official podcast ('Tetora no Oto') launched on Spotify in February 2026, and an educational 'Earth Day Declaration' and '7 Facts About Earth Day' content library. The organization's technology stack is non-proprietary and relies on standard web platforms, social channels (Facebook, Twitter/X, Note, YouTube), and pro bono infrastructure support from Members Inc.

The business model is non-commercial: EDJN is funded through donations, membership contributions, and pro bono corporate support rather than fee-for-service revenue. Forum and open meeting participation is free; networking dinners charge a nominal 2,000 yen for food and beverages. The organization licenses the 'Our Power, Our Planet™' global theme trademark from EARTHDAY.ORG for the 2025-2026 campaign cycle. Governance is led by co-representative directors (Tetora Tanizaki, Moritsu Hagiya, Arisu Okada) plus a multi-director board (Rika Bo, Hiroki Sugiura, Hiroyuki Mochida, Hatta Kentaro, Nakajima Yu) and an auditor (Hara Yutaka). SUGIZO was appointed as Japan's first Earth Day Global Ambassador in June 2023. Strategic co-creation partners include Present Tree, eumo, and Green Peoples Power for 2026, alongside longer-standing operational support from Members Inc. and EARTHDAY.ORG. No headcount, revenue, or formal funding figures are disclosed.

Customers (more accurately, network participants) span three primary segments: (a) local and regional Earth Day organizers seeking coordination and visibility, (b) the general public interested in environmental action, and (c) youth and next-generation environmental leaders. Geographic reach is primarily national (Japan) with secondary ties to EARTHDAY.ORG's global network spanning 192+ countries and 1 billion+ participants.

Core offering

Earth Day Japan Network is the official Japanese affiliate of EARTHDAY.ORG, operating a community-coordination platform that connects Earth Day event organizers across Japan and abroad. The organization delivers recurring programming through monthly online open meetings, an annual flagship Earth Day Forum each April, and the Earth Day Map — an interactive web directory aggregating 150+ nationwide Earth Day events and environmental actions. It supplements these offerings with translated global content, a podcast, and educational materials aligned with each year's global Earth Day theme.

Product overview

Earth Day Japan Network operates as a platform organization rather than a traditional product company. Its core offering is the EARTHDAY MAP — a directory and map service aggregating Earth Day events across Japan, accessible via web. Supporting offerings include monthly Open Meetings for community networking, an annual Forum for knowledge sharing and partnership building, translated global content on renewable energy topics, an official podcast, and published declaration materials. These offerings collectively function as an integrated awareness-to-action ecosystem connecting regional Earth Day organizers, environmental advocates, and the general public across Japan.

Direct peers

• EARTHDAY.ORG: EDJN is the official Japanese affiliate of EARTHDAY.ORG, the global Earth Day movement founder in 1970 spanning 192+ countries with 1B+ participants. Both operate the same brand, coordinate around April 22 Earth Day, and run annual themes; EDJN is essentially the Japan chapter of this global organization.
• アースデイ東京 (Earth Day Tokyo): The largest single Earth Day event in Japan, celebrating its 25th anniversary in 2026 and co-exhibiting with EDJN at Earth Day Tokyo 2026. Multiple directors of EDJN (Hatta, Nakajima, Bo) are also directors of Earth Day Tokyo, and the two organizations share operational heritage dating to EDJN's 2019-2021 origins.
• アースデイ in 京都 (Earth Day Kyoto): Founded by EDJN board director Mochida Hiroyuki in 2020 via his social enterprise 'Earth Conscious'. It is a regional Earth Day organizing committee operating under the same Earth Day Japan umbrella, directly comparable to EDJN's role as the coordinator of Kyoto-area Earth Day activities.

Broad incumbents

• WWF Japan: A leading Japan-based environmental nonprofit focused on biodiversity, climate, and sustainability, with corporate partnerships and member-driven fundraising. Comparable to EDJN in mission and donor/membership-funded operations, though with substantially larger scale and longer operating history.
• Greenpeace Japan: A major established environmental NGO in Japan pursuing advocacy campaigns on climate, oceans, forests, and renewable energy. Comparable to EDJN as a Japan-based nonprofit mobilizing public action around sustainability, though Greenpeace operates globally-funded campaigns versus EDJN's community-network model.
• 日本自然保護協会 (Nature Conservation Society of Japan / NACS-J): One of Japan's longest-standing environmental nonprofits, focused on biodiversity conservation, protected areas, and environmental education. Comparable in mission and educational programming, but with a conservation focus rather than EDJN's broader Earth Day coalition model.
• 気候ネットワーク (Kiko Network / Climate Action Network Japan): A Japanese nonprofit focused specifically on climate change policy advocacy, renewable energy transition, and the 1.5°C target. Highly comparable to EDJN's renewable energy and decarbonization theme alignment, but operates as a policy-oriented network rather than grassroots event organizer.
• Friends of the Earth Japan (FoE Japan): A Japanese member-funded environmental NGO affiliated with Friends of the Earth International, working on environmental justice, food, and energy issues. Comparable in mission and member-funded nonprofit structure, with a focus on advocacy and education similar to EDJN's environmental education work.

Emerging players

• Fridays For Future Japan: The Japanese chapter of Greta Thunberg's international youth climate strike movement, focused on climate activism and youth mobilization. Comparable to EDJN in mobilizing youth around climate action, but operates as decentralized activist network rather than an event-coordinating nonprofit.

Regional players

• NPO法人 環境市民 (Eco-Citizen): A Kyoto-based environmental NPO active on climate, energy, and community sustainability issues in the Kansai region. EDJN co-representative Okada operates the related 'Kotobuki' café in Kyoto, suggesting overlap in regional environmental community building, though Eco-Citizen predates EDJN and addresses a wider scope.
