Aman Kyoto is a 26-room retreat carved into 3.2 hectares of cypress and cedar forest at the foot of Hidari Daimonji, and what you're paying for (rates run roughly 360,000 to 650,000+ yen a night depending on season) is the forest, not the city. The Kerry Hill-designed rooms run 646 square feet with private Hinoki baths, sliding doors that unfold into extra space, and tatami floors that guests keep calling the best-finished wood and tatami they've seen outside a private Japanese home. The onsen, indoor and outdoor, is the reason more than one guest calls this the real onsen hotel in the Aman portfolio, and Taka-An's set menu (six ways with one seasonal ingredient, snow crab when it's in season) gets guests going back a second night.
Two things get priced in honestly. There's no pool and no gym, which a hotel at this rate would normally include as a given, and the wellness sits entirely on the traditional onsen experience instead. And the location is a genuine split: it's 13 to 18 minutes by house car from central Kyoto, which some guests find is exactly the point (a real pull from the crowds around Kinkaku-ji) and others find makes it a poor base if you actually want to spend your days out seeing the city. A few guests also flag that the main dining room is small and breakfast feels modest set against the nightly rate, and one flat-out said the delivery felt closer to a much cheaper property at these prices.
Book it if you want a few days of quiet at the start or end of a Japan trip, ideally paired with something central like the Ritz-Carlton or Park Hyatt for the days you actually want to be in Kyoto proper. If mobility is a concern, know the paths through the grounds are uneven rock, not flat. For the forest, the baths, and Taka-An, nothing else in the city gets close.
