The Site is independently operated and accepts no listing fees from facilities. Running costs are covered by the affiliate links and advertising described below. Here we explain transparently what is an affiliate link, how it is labelled, and how it does not influence our editorial decisions.
1. Affiliate partners
The Site participates in exactly one affiliate programme: the Trip.com Alliance Programme (accommodation, transport and tickets). We use no other affiliate links; links to official facility websites, maps and tourist associations are ordinary, non-affiliate links.
2. How commission works
If you click an affiliate button on the Site, complete a booking within the partner’s attribution window, and the stay or service actually takes place, the partner pays the operator a share of the sale (typically a few per cent).
Commission comes out of the partner’s marketing budget, so the price you pay is the same as if you had not used our link. There is never an extra charge.
3. How links are labelled
Affiliate links appear only as clearly named buttons (Trip.com) inside the “Book a stay” block on facility pages — never hidden in body text. Every affiliate link carries the HTML attribute rel="sponsored" so that search engines also recognise it as a paid link.
Facilities with no affiliate option (community baths, free footbaths, etc.) say so explicitly and show no booking button.
4. Editorial independence
Whether a facility is listed, its TOP 30 ranking, any “recommended” label and the tone of its description are decided independently of any commission potential. Rankings follow public sources (such as the Onsen 100 Selection) and our editorial criteria; facilities bookable through our partners receive no preferential treatment.
No content on the Site has been produced in exchange for money, free stays or goods from facilities or businesses. Should we ever publish such content, the page will be clearly marked “Sponsored (PR)”.
5. Advertising
The Site may display Google AdSense advertisements. Ads are selected automatically by Google and do not constitute an endorsement by the operator. Ad slots are visually distinguished from content.
6. A request
If the Site has been useful, booking through our buttons helps keep it running. Of course, you are free to book through any other channel, with no restriction on your use of the Site.
