I used to fly to/from NRT at least 2-3 times a year for many yrs and often hv to overnight there due to early departure/late arrival of my flights. Whenever i compare the rate of this capsule hotel (i.e. 9hours) vs the lowest single room rate(always including free airport shuttle bus between hotel and terminal) of other basic airport hotels nearby, the $ difference is typically only about 10-20%....yes, we are talking in the range of JPY 4,500-5,500 per night including tax and nowhere near JPY 10,000. Therefore, i always ended up staying in hotels around narita such as Sky Court Narita, Narita View, Marroad, Toyoko, etc. instead of the capsule of 9Hours. Airport hotel rates around NRT used to be much more expensive 10-15 years ago. Ever since most Tokyo longhaul International flights relocated to HND(Tokyo Haneda) from NRT starting from 2010, hotel room rates near NRT have dropped dramatically.
