Cons
- Only people living in Japan can open an account, shutting out overseas traders

DMM FX is run by DMM.com Securities Co., Ltd., a Tokyo firm founded in December 2006. It joined the DMM.com internet group in 2009. In 2012 it absorbed the FX and CFD clients of another Japanese broker, Gaitame Japan. Finance Magnates once ranked it Japan's top broker by account count.
DMM FX only opens accounts for Japan residents. There is no fixed minimum deposit, but margin must be at least 4 percent of trade value, which caps real leverage at 25 times. The core USD/JPY spread is 0.2 sen with no separate commission, though spreads widen a lot outside core hours. Tools include web platforms, a phone app, and a free demo.
DMM.com Securities holds about 9.8 billion yen in capital and belongs to Japan's Investor Protection Fund. It is a separate company from DMM Bitcoin, a sister firm that lost client crypto in a 2024 hack and later got a regulatory order. Reviewers like its tight spreads but flag a high 10,000 unit minimum trade size and lower swap points.
