Unfortunately, this establishment does not live up to the prices it charges. It is very run-down (in a dilapidated state in some areas). It's probably no coincidence that you can't find any photos of the common areas or bathrooms anywhere on booking sites or on the hotel's website. There was an unpleasant, hard-to-place smell in the hallways, as well as in the room where I stayed.
The air conditioning in my room was old and made a deafening noise, and was full of dust built up over years. No hot water on the first day, and very low water pressure.
I live in Japan and speak Japanese, which allows me to compare prices knowledgeably: the meals are very expensive and don't match their price. The thoroughly unremarkable Japanese breakfast, charged at 1,500 yen, can be found elsewhere for equivalent quality at 800 yen. No coffee was offered; I eventually got one made for me (tasting like UCC instant coffee) upon request, without being told it would later be charged at 400 yen. Dinner was charged at almost 5,000 yen. Again, you can find the same (mediocre) quality for half the price elsewhere.
As for the service, the owner (the only man seen among the staff) was quite rude and not befitting of a hotelier. No greeting or word of welcome, whether upon arrival or throughout the rest of my stay. Only the female staff showed any degree of warmth or consideration.
In short, this is an establishment that would benefit from renovation, better maintenance, a welcoming atmosphere worthy of a hotel, and improved food, in order to justify the prices it charges.
