Booked this as a last-minute emergency one-night stay. This ryokan is a genuine, old-school experience if you want to experience mid-20th century Tokyo. I was a bit terrified when I saw how old the facility was, especially the shared showers and the styrofoam-covered floors, but shower rooms are separated by gender and I barely saw anyone at the hostel. The toilets are squat toilets. Of all the hostels I've stayed at in Japan, this one had the most amenities—facial cotton pads, cotton swabs, feminine napkins, Shiseido(!!) toiletries and skincare products. The capsule bed was actually alright; the tv set didn't work and it did have a lingering old smell that didn't bother me too much, but the bed was comfortable and I had a good rest because my room was mainly empty. The WiFi only worked on the ground floor, I believe. Definitely an odd experience if you want to be culturally shocked and experience an urban ryokan. A bit pricey for a night, but I also booked this at the very last minute. Seems like a lot of Japanese people stay here for a quick overnight rest. Wouldn't recommend on staying more than one night, though. Good proximity to see Kyobashi/Nihonbashi nightlife and Tokyo Station.

Actually,location is so good.
Because it is near the Tokyo station.
However,
This is really really bad.
So diety and stinking.
Look my pictures.
They didn`t clean up in the room.
I couldn't sleep there.

This place is kind of disgusting and I loved it.

Each floor is basically a big room with a load of bunk beds covered in cheap beige plastic with curtains on. The inside of your 'capsule' is decked out with all of the mod cons you could need in the 80s and may or may not be held together with bits of duct tape.

For breakfast you can enjoy an ice cold coffee or Pocari Sweat from one of about a thousand vending machines that are out the front door.

It's cheap and 15 minutes from the fish market, so it met both of my requirements.
