Shuhoukaku Kogetsu is a traditional lakeside ryokan on Lake Kawaguchi, so you should book a room with a lake or Mt Fuji view early if that matters to you. Plan to arrive mid-afternoon for typical check-in around 3 to 4 pm, and be aware dinner is a set multi-course kaiseki served at fixed times, so late arrivals may miss it. Use the onsen correctly: wash before entering, keep towels out of the bath, and note tattoos can be restricted, so reserve a private bath if that’s a concern. It’s a short taxi or walk from Kawaguchiko station and close to the ropeway and boat cruises; bring some cash because smaller shops and services nearby may prefer it, and keep reservation details handy in Japanese since English can be limited.
