ESD and environmental education, in numbers

UNESCO Associated Schools, which Japan's Ministry of Education (MEXT) treats as the hubs for ESD (Education for Sustainable Development), numbered 1,065 nationwide as of 31 March 2026 (MEXT). The member list on the official website shows 2 in Saga Prefecture and 70 in the eight prefectures of Kyushu and Okinawa. Regional ESD hubs registered with the ESD Resource Center of Japan numbered 229 as of 10 November 2026, of which 5 are in Saga and 3 in Karatsu (ESD Resource Center hub list).

Karatsu Farm & Food compiled this page as part of the Karatsu Data Bank. It sets out figures on ESD and environmental education as published by MEXT, the Ministry of the Environment and the ESD Resource Center, without conclusions or evaluations. Values we counted from lists are marked as such. School and pupil numbers for Karatsu are on Karatsu Schools and Pupil Numbers Data.

The national curriculum guidelines for elementary and junior high schools published in March 2017 state, in the preamble and general provisions, the aim of raising "creators of a sustainable society" (MEXT and the Japanese National Commission for UNESCO, in Japanese).

How many regional ESD hubs are there?

Regional ESD hubs are organisations that act as a support point for people working on ESD in schools and community education. The ESD Resource Center of Japan, set up in 2016 as a joint project of MEXT and the Ministry of the Environment, began registering hubs in November 2017; by the end of January 2026, 216 organisations in every prefecture were registered (Ministry of the Environment). As of 10 November 2026 there are 229 (ESD Resource Center).

By location, Hokkaido (25) and Tokyo (22) have the most, and the Kyushu and Okinawa block has 34. Saga has 5: 1 in Kashima, 1 in Saga City and 3 in Karatsu. The three in Karatsu are the city's environment division, an NPO working to conserve the Nijinomatsubara pine forest, and Karatsu Farm & Food (our count from the list).

Our counts on Karatsu's islands

As part of Saga Prefecture's "Plasma LIFE Saga" initiative, we have worked with the school of one Karatsu island a year since FY2023, collecting and surveying beach litter and turning bottle caps into island-shaped key rings and coasters (Island ESD). The table above shows figures counted in that work.

Notes on reading the figures

Prefecture counts of UNESCO Associated Schools are search counts on the official member list; their total (1,064) differs in date from MEXT's 1,065 (31 March 2026). Counts of regional ESD hubs by prefecture and city were made by us from the location field of the hub list; registration does not measure the amount of activity. Experience opportunity sites are counted in "sites" or "organisations" as written in each source.

What this page does not cover

This page does not evaluate individual schools or organisations, does not compare schools or prefectures, does not count ESD activities at schools outside the UNESCO network, and does not use values read off charts. Japanese sources are summarised in our own translation; the originals take precedence.
