Japan's government said Bitcoin isn't a currency amid calls for its regulation a week after the bankruptcy of Mt. Gox, the Tokyo-based exchange that was once the world's biggest.
There is no law to define Bitcoin and relevant ministries are gathering information on it, Prime Minister Shinzo Abe's cabinet said in a statement in response to questions from an opposition party lawmaker. Bitcoin transactions can be taxed, according to the statement obtained by Bloomberg News.
Japan isn't the only country grappling with the regulation of Bitcoin amid reports of hacking into exchanges including Mt. Gox and concern that the virtual currency can be used for money laundering. In the U.S., states are wrestling with how digital-currency businesses could be regulated as money transmitters, while Russia has said Bitcoin is illegal under current law and Finland plans to treat it as a commodity.
