Affiliate links: Most booking links are affiliate links. If you book, farepage earns a commission from the seller at no extra cost to you.
Commissions do not set the order: Hotels are listed by search demand; tours keep the seller's own popularity order (Viator's default ranking), limited to products rated 4+ with 20+ reviews. We do not reorder by commission rate.
Which hotels we list: Three stars and up in Japan and Korea, four stars and up elsewhere, and only hotels people actually search for or that have many reviews.
Prices are indicative: Prices are the seller's rates when collected and change with dates, rooms, availability and exchange rates. Check the final price with the seller before booking.
