Affiliate disclosure

Japan Pet-Friendly Onsen 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 pet-friendly 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.
