Japan is traditionally home to many forex & CFD brokers who set up local branches there to serve the large number of Japanese traders. Among these brokers are also some that offer stock trading with contracts-for-difference (CFDs). This means that it is possible to get exposure to popular stocks both long and short, and with much higher leverage than what is available from traditional stockbrokers.
All brokerage companies in Japan are strictly regulated by the Japan Financial Services Agency (JFSA). This is a highly regarded and well-experienced regulator, which is known to keep brokers to the highest standards. In addition, the JFSA also has a history of doing its best to prevent Japanese traders from trading with overseas forex brokers, which is one of the reasons why so many brokerage companies have set up local branches in Japan.
