There seem to be more places to go in the Old Town area, but I came to Chiba because it was 3 minutes away from my accommodation! I went right after opening time on a weekday, asked if a reservation was possible, and paid on the spot with Klook. For the Office Syndrome package, you can choose Your Retreat? You can think of it as taking off everything and wearing only sanitary panties, followed by an aroma oil massage and herbal ball steaming. It's not as strong as a Thai massage, but it's so refreshing, and it was really nice to receive it alone in a private space where no one was. It was nice that I could shower afterward, but please note that there is no hairdryer. The masseuse was nice, and the kindness of the reception staff seems to vary. Some people are kind, but since they don't understand English, they gossip among themselves, which wasn't very pleasant. So I recommend it!
