Capsule Hotel Rex Inn (Kawasaki, Japan)



This capsule hotel is located very central to the city of Kawasaki entertainment area – many pachinko places (the Japanese version of fruit machines), bars and restaurants plus across the road is a huge mall. From HND airport it takes about 15 minutes on the Keikyu Main Line, if direct. The station is Keikyū Kawasaki Station in which is about 10 minutes or so walk from the capsule hotel. As you exit into Kawasaki, you come out by a taxi stand, cross the main road and walk right for about 500 metres you will find it. The hotel is opposite a hospital if you need to ask for directions.


This was my first experience in staying in a plastic capsule, mine did not have a TV but a fan. This I thought is a good idea as i can’t sleep if i am too hot, but when the shutter is down it simply circulates the warm air because of lack of ventilation, though a very small and weak AC vent.
In terms of space there is a small side table on one side of the wall, ideal only for a phone or small book. There is also a plug socket right next to your head! Plus a unit for dimming light and alarm clock radio. Since capsules are not allowed to be locked there is a small wooden shutter to pull down for privacy but even with fan on I felt very hot. The bedding is quite hard and the pillow was unusually hard, as it was a traditional Japanese rice pillow.

My capsule was on the top row, with small steps to get down between capsules. Going to the toilet in the middle of the night is quite a challenge since it is hard to see the steps and jumping down would be noisy; likely to wake other guests. The system at the hotel works that you leave your luggage in a locker two floors up, they provide towels for the spa and a t-shirt & shorts as pyjamas. Be wary the lockers are quite small so my bag, which is the largest you can use for carry on, was hard to fit in. You cannot leave items inside your capsule unattended since they are not lockable and to avoid repeating journeys you should grab what you need with you for sleeping in one shot. I brought my laptop in the aim to do some work but it simply is too uncomfortable to use with the size of the capsule – it was ok to sleep with laptop on side against wall but I wouldn’t recommending bringing much.
I am not claustrophobic but definitely don’t go if you are. My other advice is to bring ear plugs but if not, the hotel does sell them in the lobby shop. My whole floor of 30+ capsules seemed full and some loud snoring can make it hard to sleep. Though its excellent value for money the sleep comfort factor was not great, I simply felt too hot after about 5 hours of sleep and even after opening the shutters felt hot but it was an experience that needed to be done.


The hotel offers free WIFI that worked in most places of the hotel. On every floor of the 8 storey building is a small room with sofa and TV and ever other floor has a dedicated well ventilated smoking room. The locker room have Pachinko machines (fruit machines) plus massage chairs and even washing and drying machines. Each floor also has a toilet with 2-3 washlets but for showers, its all very communal on the top floor at the traditional Japanese spa. There is a hot dry sauna with a TV inside, three pools, one freezing, great after the sauna, and others are hot with one of the two outside. For new comer westerners, be aware its all very naturist. There are many sinks around the room with showers and small seats, which offer free toothbrushes and razors, shaving gel and full large bottle of shampoo, conditioner and liquid soap.
On one of the floors is a cafe that serves simple Japanese food plus vending machines. On the same room are a line of reclinable chairs in front of TV’s for relaxing after a hot sauna and an area with desks to work from with a mini library, mostly manga.
On the ground floor pre-reception are shoe lockers since you cannot bring your own shoes in, resulting in everyone walking around bare foot or in their own slippers.
There is a small snack shop as well as items like ear plugs.


The staff are polite enough though they don’t speak much English. The Rex Inn is really for Japanese business men sleeping off a hangover or staying at a cheaper place. Its not that foreigner friendly, there is no guide or much information given when checking in. I did feel a bit alien here since I seemed to be the only non-Japanese. However considering the guests are all in close proximity, no-one talks to each other so I guess this is cultural. However, for £22 it was very reasonable and alongside the spa offered good value for money. I doubt I will stay at here again if I was in need of a decent rest.
