Japan News

Located in East Asia, Japan is a top 20 country in the world in terms of population. Japan has the third-largest economy by nominal gross domestic product and the fourth-largest economy by purchasing power parity. Tokyo is the country’s capital. Bitcoin in Japan has a notable following, as does cryptocurrency and blockchain as a whole.
The country’s regulators have deemed Bitcoin an approved money type. Japan hosts a number of crypto exchanges, and the country has regulatory requirements around the industry, creating a scene more favorable for compliant crypto-asset entities. Bitcoin’s anonymous creator, Satoshi Nakamoto, is thought to be from Japan, although little is confirmed about Nakamoto’s identity.
