Dokoyuku | Hotel Vacancy Search by Date

After researching major hotel booking sites, I couldn't find a service that allows you to search for available hotel rooms across the entire country based on dates, so I developed one myself. When you select a prefecture and dates, it displays a list of available hotels sorted by price or distance from your starting point. You can use it when you think "I want to go somewhere for the weekend, but haven't decided where yet." It uses vacancy data from Rakuten Travel.
