When it comes to having a good night’s sleep, bed size matters. However, in Japan, sometimes the simplest of tasks can be made difficult. That’s why I’ve put together a size guide to make choosing a bed a little easier. 

The first rule of thumb is to completely forget all the bed terminology you already know. Hotels try to accommodate foreigners by using terms like ‘twin-bed’ or ‘double-twin’ which simply do not exist in Japan. 

Please check the size guide below:

Single (97cm x 195cm)

In Japanese hotels, a single bed is equivalent to a twin bed. A twin bed sounds a little more generous, doesn’t it? Of course, I shouldn’t forget to mention the infamous capsule hotels which are adored by many for their convenience and solitude. Japanese apartments can be quite small, so the single bed is popular for adults in tight spaces. Interestingly it’s also favoured by individuals who use their loft space to catch some Z’s. Single beds are also a great option if you plan to have a sofa bed, as they don’t take up any extra space.

 Semi-Double (122cm x195cm)

The name ‘semi-double’ is unique to Japan and refers to a smaller double bed. Many people describe the semi-double as being between the single bed and the double bed. Hotels often offer the semi-double as an upgraded single option, while not the largest, it can accommodate two adults. Semi-doubles are likely the most popular option for co-habiting couples or for singles who find a single bed too small. Many individuals also use a futon the size of a semi-double as it saves a lot of space while remaining comfortable. 

 Double (152 x 195cm)

A double bed is a very common size for hotel rooms. However, don’t be fooled; this isn’t the same double bed you’re familiar with – it’s smaller than what you’re used to. If you’re travelling, this size should be sufficient and can comfortably accommodate a couple. In apartments, double beds are more of a luxury and not a necessity, even for those with space. 

 Queen (170cm x 195cm)

A Queen size bed in Japan is equivalent to a King size bed everywhere else in the world. This is perhaps the largest size you can get at hotel rooms and one of the biggest bed sizes you can have in your apartment, although it’s relatively rare. 

 King (194cm x 195cm)

A King size bed is practically non-existent unless imported. Catering to this size is also challenging as many shops would need to find a specialist to fulfill such requests.

If there’s one thing to take away from this article, it’s that bed sizes in Japan are smaller than what you’re used to. If you’re seeking a balanced option, you cannot go wrong with a semi-double – it’s better to be safe than sorry.
