I was travelling on my own and decided to try the capsule hotel experience for fun. I didn't have many expectation, I thought it's be a dormitory hostel experience, probably noisy and not very comfortable but it was actually so much better than what I expected!
Very friendly staff, they have English support ready on a tablet if you're not too good at Japanese (like me!) and every sign has an English translation.
Everything was very clean and antibacterial hand wash was also available. As a corona prevention measure, wearing a mask in public space and temperature check prior to check in are mandatory.
The dormitory was very quiet at night on the girls' side, so much that I was worried to make to much noise when turning over!
The sleeping pod was sparkling clean. The mattress has the thickness of a regular single sized futon, it might be a bit hard if you're not used to it maybe (I can't say for sure, as I'm used to thin futons).
There's a lounge area on the top floor, note that you are not allowed to smoke there, even on the balcony.
I didn't try the coffee because I was in a hurry but they seem to make their own blend!
