First Cabin Akihabara

Already familiar to regular travellers at Haneda Airport, the First Cabin chain opened its second souped-up capsule hotel in Akihabara in summer 2013. First Cabin Akihabara follows the same format as the Haneda Airport hotel: guests stay in 'cabins' with high ceilings and unlockable, sliding doors, while sharing toilets and bathing facilities. Rooms are available in both 'business class' and 'first class' versions (from ¥4,900 and ¥5,900 per night, respectively); opt for the latter if you want to have space for your luggage. If you're just searching for somewhere to take a break during a hard day's shopping in the local electronics stores and geek boutiques, you can also get rooms for short stays of two hours or more during the daytime (from ¥800 per hour).
