We are Canadian grandparents who have Japanese family in Tsukuba-shi. We want to rent in Ozone area where they live, in Spring 2027 between March and June. Visitor visas only allow us 90 days so we want to stay that long. We have stayed for 90 days 2 other years and rented homes but those aren't available now. Please let us know if anyone has a place to rent during those months.
