Guide dogs and other assistance dogs (guide dogs, service dogs, and hearing dogs) are allowed to enter the venue, pavilions, and facilities including toilets.
If an assistance dog from overseas is recognised as meeting Japanese standards through training by an accredited overseas training provider, a "limited-time certificate" will be issued by the Japanese accreditation body to ensure peace of mind during the dog's stay in Japan, and ensure the dog will be treated as a similar assistance dog.
