Having never stayed at a capsule hotel I finally decided to try one out and chose this place after reading some favorable reviews.
The hotel is about 5-10 minutes walk from the east exit of JR Shinjuku station. It is also across the street from the Nishi-Shinjuku subway station exit. I had a difficult time finding the place. There was only a small sign outside the building on the street level. You have to enter the building, pass through the atrium, go downstairs, then take an elevator to the 3rd floor to check-in. Once in the building there was a sign with English directions.
On arrival, each guest takes off his shoes and stores them in a small shoe locker. The shoe locker key is given to the attendant upon check-in. You can retrieve the key if you want to leave the hotel, which is allowed as often as you like. Then you get in line to check in. The personnel at the check-in desk knew only minimal English but did give me a sheet of instructions written in Japanese, English, Chinese, and Korean.
I elected to get a deluxe capsule and was given a key attached to a wristband and a set of pajamas. The wristband has your locker number on it and it's the same number as your capsule. You are suppose to wear the wristband at all times while in the hotel. After changing out of your clothes into the pajamas and stowing your belongings in the locker, you are free to roam around. If you have items that do not fit in the locker, you can check it for free at the counter just around the corner from check-in. That's also where you can buy just about anything you need such as underwear, socks, shirts, ties, and other assorted items.
The bathing area was spacious with numerous open stalls. Make sure you understand the etiquette of using a Japanese public bath. All the necessary toiletry items were provided free including towel, toothbrush, comb, razor, shampoo, conditioner, bodywash, aftershave, cologne, hairdryer, etc. There was a large indoor bath, a small outdoor bath, a small outdoor whirlpool, and several saunas. Various types of massage service was also available for a fee.
Another floor offered food service. It was divided into a smoking section and a non-smoking section. All the tables were single seating (it reminded me of my high school table with the seat attached) facing the front where a TV blared (again reminding me of my high school class with the TV replacing a teacher). The wait staff knew even less English than the check-in staff. When you place your order, they scan the barcode on your wristband and the amount is placed on your hotel bill to be paid upon checkout. Like many Japanese restaurants, water is self-serve. The prices were reasonable and the food was nothing to get excited about.
Another floor offered napping areas, cubicles for working on your computer, and TV viewing. There was also a smoking room. Each floor offered public bathrooms with both Japanese and Western style toilets.
The cubicle itself was spartan. There was a small TV, radio, alarm clock, and light. You can buy a card to watch pay-per-view on your TV. The bed was very firm but not unexpected in a Japanese hotel. There was a small buckwheat-type pillow. A roll-down shade covers your capsule entrance for privacy. Because it is just a pull-down shade you could hear your neighbors, especially if someone is talking. I recommend earplugs for light sleepers. Although generally not a light sleeper I was awakened several times during the night when people would come back to their cubicles (remember that many people are out partying until late in Shinjuku). I could also easily hear several of my neighbors snoring. The cubicle may be too short for those over 6 feet tall. I'm 6 feet and my toes were poking at the privacy shade while my head was up against the wall.
As others have mentioned, make sure you check out by 10 AM. The line actually took a while because everyone was checking out at around the same time, so as long as you're in line I think you'll be OK. Even if you are staying consecutive nights, you are required to clear out your locker and check out each day. I imagine that can be a hassle.
During my stay, I did not see a non-Japanese at the hotel. However, I did not feel uncomfortable staying there and enjoyed the experience. The hotel does have a no tattoo policy, whether Japanese or foreigner. It is also only for men. The upper levels are for women and use a different set of elevators.
Overall I think this is a very reasonable priced option for a short-term stay. The location is very convenient and close to Shinjuku where eating, drinking, and entertainment options abound. And it offers a glimpse into an unique Japanese experience.
