Fantastic for a couple. It was our honeymoon vacation, and we enjoyed this hotel the most out of all of them. It’s a love hotel. This concept means the staff is rarely seen and the idea is to have a “private” spa all to yourselves. These are uniquely a Japanese concept, so the English is so-so to not at all. But they are extremely friendly and google/Apple translate will get you through what you need.
I recommend learning basic ordering vocabulary before you come, just to make it easy though. Don’t forget your phone can translate images too, so that will get you through the menus as well.
Also, sometimes, they don’t notice you standing at the front desk through the camera. A polite knock and a “sumimasen” will get someone to come say hi. The front desk is on the second floor.
Also, don’t worry about the “check out every day part” that’s them deep cleaning all the rooms. Your luggage can stay in the room. Just go sight see or explore, that’s what a vacation is for right? Takeda station is only a 15 minute walk away.
