OTAs outrank your property for your own destination searches
Search "ryokan Kyoto" or "onsen hotel Hakone" in English. Booking.com and Expedia dominate the results. Search in Japanese and Jalan.net and Rakuten Travel take the same positions. Your property's direct website — if it ranks at all — appears further down. Guests arriving through these OTAs cost you 15–20% commission on every stay.
