Extremely friendly and helpful staff, they spoke good English.
The hotel has a club with gym, pool and sauna/spa facilities, it costs around 5000 yen for a day pass (I got 2000 off for my first time, so I paid 3000) and it’s really worth it; while the gym does not have many machines for weight training, it’s clean and well kept. The pool is big and well taken care off with separate swimming lanes. Finally, there’s a sauna, a hot and cold jacuzzi, and a shared bathroom with showers, razors and an assortment of grooming utensils (note that people are naked here if that makes you uncomfortable). This was a really relaxing experience and sets you up for sleeping quite nicely! I’d recommend going later in the day, they close at 9pm.
