TOKYO — Japanese LGBTQ rights activists on Wednesday hailed Tokyo’s move to introduce a same-sex partnership system as a huge step in their fight for equality in the only G7 (Group of Seven) country that does not fully recognize same-sex marriage.

Tokyo governor Yuriko Koike on Tuesday said the Japanese capital will draw up a framework allowing the partnerships early next year with an eye on making them legal in the fiscal year beginning April 2022. The extension of the system to Tokyo could potentially end up benefitting over 50% of the country’s population.

Under the system, same-sex partners can register their relationship and gain some of the privileges enjoyed by married couples, such as being allowed to rent places to live together and gain hospital visitation rights.

Though it falls short of a legal marriage, Tokyo’s move to adopt the partnership system is seen as an important step towards legalizing same-sex unions in a nation where the Constitution still defines marriage as based on “the mutual consent of both sexes.”

“This is amazing news,” said Masa Yanagisawa, head of Prime Services Japan at Goldman Sachs and a board member of activist group “Marriage for All Japan.”

“Some conservatives have voiced concerns that even though these partnerships are just symbolic pieces of paper, they could undermine Japanese traditions or the traditional Japanese family system. Hopefully this will be a chance to prove otherwise.”

Tokyo’s Shibuya ward in 2015 was the first place in Japan to introduce the partnership system. The system already covers 41% of Japan’s population and the extension to Tokyo means over half of the nation could potentially benefit, according to campaign group Nishiiro Diversity.

Activists have long lobbied for the whole capital city to adopt the system, and stepped up such efforts ahead of the Tokyo 2020 Olympics, delayed by the coronavirus pandemic until this summer.

“There may have been some restraint towards the national government and the fact that a lot of ruling party lawmakers are reluctant about this,” said Takeharu Kato, a lawyer in charge of a landmark court case in March that said barring same-sex marriage was unconstitutional.

While Tokyo as a whole did not adopt the partnership system before the Games, the Olympics, with its focus on diversity, helped sway public opinion, Kato and others said.

A recent poll of Tokyo residents conducted by the metropolitan government found 70% of respondents were in favor of same-sex partnerships.

“I’m sure the Olympics had an impact since Tokyo has been thinking of what kind of legacy they should leave,” said LGBTQ rights activist Gon Matsunaka.

Another incentive has been Tokyo’s interest in branding itself a major international center and attracting foreign companies, many of which have greater emphasis on LGBTQ rights.

As part of Governor Koike’s preparation for her announcement, she spoke with foreign business leaders, who said Tokyo was behind on that front, said Goldman’s Yanagisawa.

“From my perspective as a Goldman Sachs employee, we want to attract international talent but Japan is always at a disadvantage,” he added.

“We offer our own employee benefits on top of the national provisions to try to equalize the system but there’s a limitation to what is possible, and obviously not every company can do this.”

The next goal is making marriage possible, though this probably requires more local areas to adopt same-sex partnership regulations, creating enough pressure that the national government can no longer ignore it.

“Of course I’m happy,” said Kato. “But this is just one waypoint on a long road. We need to use it to push towards actual marriage.”  Reuters
