the same prefecture. Mutual recognition of certificates Between cities On October 30, 2019, the cities of Fukuoka and Kumamoto announced they would recognize each other's partnership certificates effective immediately. This marked the first time that two or more jurisdictions in Japan had begun recognizing each other's certificates, easing recognition for same-sex couples. This means that if a same-sex couple with a certificate moves between both cities they need not reapply for a certificate in their new city. Since 1 April 2020, certificates from Kitakyushu and Koga are also recognized between the four cities. Certificates from Okayama, Nichinan, and Karatsu are also recognised in Fukuoka. On December 2, 2019, the mayor of Yokosuka announced his intention to establish a joint recognition scheme with the fellow Kanagawa cities of Zushi and Kamakura, taking effect on 1 April 2020. Hayama joined the scheme on 1 July 2020, and Miura joined on 1 January 2021. In July 2020, Okayama and Sōja agreed to mutually recognize their certificates and eliminate the need for new procedures when couples move between the two cities. Okayama reached a similar agreement with Fukuoka in November 2020 and Hiroshima in January 2021. Hiroshima and Akitakata also mutually recognize their certificates. The cities of Katano and Hirakata decided to recognize each other's certificates in June 2021. Since then, numerous other cities have also established such mutual recognition schemes. On 1 February 2022, a similar agreement took effect between Chigasaki, Fujisawa and Samukawa. The cities of Chiba and Yokohama made a similar recognition agreement in January 2021, effective on 1 February 2021. In early April 2021, the cities and towns of Amagasaki, Ashiya, Inagawa, Itami, Kawanishi, Nishinomiya, Sanda and Takarazuka, all in Hyōgo Prefecture, agreed to recognize each other's certificates. Likewise, in May 2021, 12 municipalities in Tokyo, Adachi, Bunkyō, Edogawa, Fuchū, Koganei, Kokubunji, Kunitachi, Minato, Nakano, Setagaya, Shibuya and Toshima, agreed to mutually recognize their certificates. Upon establishing its own partnership registry in November 2022, Tokyo Metropolis recognized all partnerships previously registered in Tokyo's wards and cities. Between prefectures On 18 August 2022, Saga and Ibaraki prefectures announced they would recognize each other's partnership certificates, becoming the first prefectures to do so. Saga Prefecture completed a similar agreement with Fukuoka on 24 November. On 20 December, mutual recognition was established between Ibaraki, Tochigi and Gunma prefectures. On 31 January 2023, Ibaraki signed an agreement with Mie. List As of 1 February
