The conference brief
Past editionJapan Climate Action Summit 2026
The Japan Climate Action Summit is a free half-day summit organized by the Japan Climate Initiative, a coalition whose secretariat is co-organized with CDP Japan and the Renewable Energy Institute, held at the U Thant International Conference Hall at United Nations University in Tokyo with Japanese-English simultaneous interpretation and an online viewing option. It puts Japanese corporate sustainability leaders and policymakers in one room around the energy transition, nature-positive and circular-economy approaches, and corporate decarbonization frameworks like SBTi, TNFD and ISSB, though it runs as a speaker summit rather than a trade show with an exhibit floor.

01 / Make the call
Is this the right room?
Emitree's assessment of audience fit. Conference access does not establish buying intent or guarantee meetings.
Consider it if
You sell ESG or CSRD software, carbon accounting, or sustainability advisory services to Japanese enterprises and want free face time with decision-makers at Japanese corporates and CDP-network companies. Book the in-person room, not the Zoom link, since the post-program networking session is in-person only.
Consider another event if
You need booth space, a buyer database, or high attendee volume to justify the trip. This is a single afternoon of keynotes and panels with no exhibition floor.
02 / Understand the audience
Who attends
Keynote speakers are Johan Rockström of the Potsdam Institute for Climate Impact Research and Naoko Ishii of the University of Tokyo, with Chris Wheat of America Is All In as guest speaker and Japan Climate Initiative co-representatives Sergio Shigeo Kato and Takejiro Sueyoshi opening and closing the program. Panel discussants come from NTT DATA, E3G, the Renewable Energy Institute, Unilever Japan, Toyooka City, Kirin Holdings, WWF Japan, Daito Trust Construction and CDP Japan. No attendance figures, venue capacity, or attendee job-title and seniority breakdown are published. The organizing body, Japan Climate Initiative, is a coalition of Japanese companies, local governments and NGOs committed to climate action.
How large is the event?
No attendance figures or venue capacity are published by the organizer. The event runs as a single afternoon program from 2:00 to 6:00 PM JST, with room access from 1:15 PM, in one conference hall at United Nations University, followed by a networking session for in-person attendees. The online option runs through a Zoom webinar with no published capacity.

Edition notes
On-site registration only opens 2 September 2026, roughly a month before the summit, so sellers wanting an in-person seat should watch for that registration link rather than trying to register now. The online Zoom option is open immediately, but the post-program networking session is limited to in-person attendees, so remote participation costs you the part of the day where conversations actually happen.

The practical questions
Before you decide
Is Japan Climate Action Summit 2026 still upcoming?
This edition ended on October 2, 2026. We have no later confirmed edition in this guide. Use the information as historical context.
Where can I find the Japan Climate Action Summit exhibitor list?
We have not linked a public exhibitor directory for this edition. Ask the organizer about current directories and attendee access.
Does a company listing confirm who will attend?
A sponsor, exhibitor or speaker listing establishes that published role. It does not establish which employees will attend or whether they are buying. Previous-edition examples remain historical.
How can Emitree help with Japan Climate Action Summit?
We can research relevant accounts and prepare follow-up using your event notes, contacts and public sources. We qualify the accounts against your offer and run agreed outreach in your team's voice.
