From the WSJ blog: 

Tokyo’s Shibuya ward said Friday that it will start accepting applications for same-sex partnership certificates beginning next week after passing an ordinance earlier this year that permits the ward to recognize the partners equivalent to those married under the law.

According to the ward, same-sex couples applying for a certificate must both reside in Shibuya and be at least 20 years old. They must also be unrelated and have no spouses or other same-sex partners. The ward will also require that the couple submit notarized documents proving their relationship.

The ward said it will start issuing the certificates beginning Nov. 5.
