What you're trying to book
The flagship Hoshinoya property in the Karuizawa mountains. Hoshinoya Karuizawa is a traditional ryokan in Karuizawa. The price sits at ¥¥¥¥ — expect the full seasonal menu at dinner and a shorter format at lunch where available.
How reservations actually work
The restaurant does not publish a direct booking channel. A hotel concierge or a private introduction is usually the only path.
Peak seasons (cherry blossom in early April, autumn leaves in mid-November) fill three to six months out; weekday lunches are usually the easiest slot for a first-time visitor.
