Semi double room意思
"Semi double room" is a term used in Japan to describe a type of hotel or accommodation room that is slightly larger than a single room, but not quite as large as a standard double room. The term "semi double" typically refers to a room with a bed that is wider than a single bed, but narrower than a standard double bed in Japan.
In Japan, a standard double bed is usually around 140-160 centimeters (55-63 inches) wide, while a single bed is typically around 90-120 centimeters (35-47 inches) wide. A semi double bed is somewhere in between these widths, usually around 120-140 centimeters (47-55 inches) wide.
Semi double rooms are a popular choice for solo travelers or couples who are looking for a bit more space than a single room, but who don't need the full size of a standard double room. They are also a cost-effective option for travelers who are on a budget, as they are usually priced between a single and a standard double room.
