How to dispose of trash
Regarding how to dispose of garbage, the most inconvenient thing for travelers while traveling in Japan may be that "garbage bins cannot be found in town." Currently, in Japan, not many garbage bins are installed on the roadside, mainly for security reasons. In many countries in the West, there are many places where you buy coffee, etc. for take-out and carry around, and there are many customs that you throw them away in many trash cans on the roadside where you finished drinking, but unfortunately in Japan you cannot expect that casualness.
When you buy a drink for carrying, the places where you can throw out the empty can are very limited, and there is a possibility that a trash can is installed in the station platform, or in a store such as a convenience store. However, in the case of shops, the act of only disposing of garbage without purchasing anything is frowned upon. In contrast, when you hire a rent-a-car, check in at a hotel, etc. or you receive some kind of service and ask for it, they may be willing to accept garbage.
Just because there is no garbage can, don’t consider leaving garbage at the roadside as it is, as acts such as littering are considered very embarrassing in Japan, showing lack of consideration for the surroundings. With caution in mind that it is hard to find a trash bin, you are required to take garbage home.
Regarding household garbage, detailed rules are decided based on the rules of each municipality, and each household sorts and separates garbage. Although the fineness of the sorting seems to be talked about in the overseas media as well, it can be said that it shows the Japanese people’s high awareness of recycling. Combustible garbage, incombustible garbage, and recycling (PET bottles, cans, bottles) are three major categories, but in many places, there are more than 10 categories. While traveling, you do not have to grasp all of them, but when you stay at a Minpaku (private lodging), etc., you need to classify the garbage according to the rules decided by the owner. Basically, there is no need to sort garbage when staying at an accommodation such as a hotel or a ryokan.
