Ibaraki, Osaka
In February 2015, the ward of Shibuya (in Tokyo) announced plans to establish a partnership system that would recognize same-sex couples for situations such as hospital visits and shared renting of apartments. This procedure allows couples to get a "proof of partnership" paper, which does not have any weight under Japanese law but can help in, for instance, getting access to a partner who is ill and in hospital but institutions are under no legal obligation to respect the certificates. The Shibuya system is considered a significant step towards lesbian and gay partnership rights in Japan. In July 2015, Tokyo's Setagaya ward announced that it would be joining Shibuya in recognizing same-sex partnerships from November of the same year. Since then, 100 municipalities have begun issuing partnership certificates, including highly-populated Yokohama, Osaka, Sapporo, Fukuoka, Kyoto, Kawasaki, Saitama and Hiroshima, as well as three prefectures, namely Ibaraki, Osaka and Gunma.
