Affiliate disclosure

Japan Private Onsen Family Hotels participates in affiliate programs (commission-based advertising). If you book through our Booking.com, Agoda (e.g. Travelpayouts), Rakuten Travel, or Jalan links, we may earn a commission at no extra cost to you.

Booking and comparison CTAs are marked with Ad. Listing criteria prioritize verified private onsen facilities from official sources—not who pays the highest commission.

Affiliate IDs are configured via environment variables:

• NEXT_PUBLIC_BOOKING_AID — Booking.com aid
• NEXT_PUBLIC_TRAVELPAYOUTS_AID — Agoda / Travelpayouts marker
• NEXT_PUBLIC_RAKUTEN_AID / NEXT_PUBLIC_JALAN_AID — secondary Japanese OTAs

Until IDs are set, CTAs deep-link to public Booking / Agoda search for the hotel name + Japan and remain labeled as affiliate / ad.
