What's so good about this place? They provide everything you could possibly need and the capsules are much more comfortable than you would imagine. It's also tattoo-friendly and many of these places aren't — a sign out the front even warns Japanese guests about it. It's great because you can use the artificial onsen (hot spring). And there are free massage chairs.
And the bad? It's men only, so if you're a woman you'll have to find a different capsule hotel. They're usually gender-segregated. Also the hotel is Bali-themed for some reason and when you're in the communal areas this traditional music plays constantly - it gets a bit grating after a while.
What's in the neighbourhood? Ogikubo is known for having lots of ramen shops and they are great. I also frequented a small video game arcade on the street and lost a bit of money on the claw machines.
Toiletries: The bathrooms have everything — and I mean everything. Cleanser, toner, moisturiser, shaving cream, aftershave, mouthwash, razors, toothbrushes, combs and so on. Down at the communal bathing area there are multiple shampoos and conditioners, as well as a whole bunch of designer colognes.
Food and drink: The hotel offers free Japanese curry for breakfast — the best feed for a salaryman apparently — and at all times you can help yourself to miso soup and tea. There's bar beers, sake and spirits as well as tempura snacks.
The bed: Surprisingly comfortable — much better than the one in the cheap hotel I stayed in previously. They offer a choice of five types of pillow for different needs.
A room with a view? A view of the 40-inch TV.
Bathroom: On the capsule levels, there's are plenty of sinks with the aforementioned toiletries. The toilets are the classic Japanese high-tech variety, with bidet, warming seats and fake flushing noises to preserve your dignity.
If you're shy, this isn't the place for you. The showers and onsen are communal and you will have to get naked in front of others. No one's really looking though.
Free Wi-Fi? Yes and it was quite good.
Noise: A bit of snoring and walking in and out throughout the night/morning, but you'll be so tired from walking around it doesn't really matter.
Value for money: Probably the best-value stay I've ever had.
Perfect for: Solo travellers, dudes, salarymen.
