As you can see from the photos, this is a pretty special place. 皎月山莊 has really put a lot of effort into a really great mix of traditional and modern in this huge space. The real highlight were the suggested activities which 皎月山莊 can arrange - tea ceremony, kendo sword training an display (kids absolutely loved this - and it was all done in English), dinner with the fireflies, hiking up Mt Takao. All brilliant. Be sure to book these in advance though. Whilst we didn't speak any functional Japanese this was not a problem as all communcation with our hosts was translated without any misunderstanding or ambiguity. The house sits right at the edge of the metropolitan area so all the shops/amenities are there, but a 5 minute drive and you're into the beautiful mountains. Highly recommended.
