Japan has plenty of unique customs and traditions that cannot be found anywhere else, such as:
Homes and Inns in some parts of Japan use traditional mattresses called "futon" instead of beds.
Futons are still widely used because Japanese people customarily use tatami mats.
The vending machines found along roads are part of Japan's rich and unique culture.
No country other than Japan has as many vending machines scattered across the city.
This is a testament to the state of public order and security in the country.
The custom of bowing always manages to leave a positive impression on foreigners coming to visit Japan.
In Japan, people greet each other by bending at the waist and lowering your head in a bow, in contrast to other countries where they shake hands and look at their counterpart's eyes.
Stop when red light; go when green light
It may be acceptable in other countries to cross the street even when the lights are red for as long as it's safe to cross, but visitors often find it strange that in Japan, people will not cross a red light even in the dead of night with no cars on the road.
Slurp when eating noodles
In Japan, it is also considered good manners to not make unnecessary noise when eating - except when eating noodles such as ramen, soba and udon.
Slurping while eating soba for example, is considered tasteful and chic.
