If you take a walk around Tokyo, especially near the parks, you will probably notice many homeless people along the sidewalks or in makeshift homes. It is very unlikely that you will find garbage cans anywhere on the streets, though. The Japanese people say that the reason this is true, is that the Japanese want to discourage homeless people going through the trash and disturbing people. It has also been said that this was done after the Sarin Gas attack in the Tokyo subway, because the gas was put in a garbage bin.
Either way, if you have anything you wish to dispose of, you must enter a shop or another building and throw it away if there is a garbage can inside or ask an employee. Most likely, they will throw it away themselves.
There is rarely English written menu in restaurant and cafe.It's written almost in Japanese.
And big problem,A lot of Japanese cannot speak English.
But if you speak in English slowly,they'll manage to explain.So many people are kindly.
Please take note, if you are in Japan on a tourist Visa it is Illegal to be without your passport..... even to visit the shops! If you do not carry your passport you can be arrested and even deported.
PS. police in Japan can hold you for 30 days without charge
This is not a vital warning, it's more some statements about travelling here.
- Outside of metropolitan areas your foreign credit card is maybe not accepted; this happened to me outside Kyoto, on a smaler railwaystation, where I wanted to buy a trainticket.
- From Public phones you can't make an international call, and "western" cell phones don't work here.
