In Japan, gambling is generally illegal under the Criminal Code chapter 23. However, there are a few exceptions to this rule. For example, certain types of gambling, such as horse racing, bicycle racing, and motorboat racing, are allowed and regulated by the government. Additionally, the government has recently passed a law allowing for the development of integrated resorts, which will include casinos.
However, it is important to note that even with these exceptions, gambling is heavily regulated in Japan. For example, there are strict rules around the operation of pachinko parlors, which are popular gaming establishments that resemble slot machine arcades. Additionally, the government has taken steps to combat problem gambling, such as limiting the amount of money that can be spent on certain types of gambling and requiring operators to take steps to prevent addiction.
Overall, while there are some forms of gambling that are legal in Japan, it is important to be aware of the strict regulations and limitations that are in place.
