About ICOs and ICOs in Japan

ICO stands for Initial Coin Offering which are often called “token sales”. With this method, a company or project can sell assets digitally as electronic tokens to raise funds from the public.

In Japan, utility tokens sold in ICOs are considered to be “cryptocurrencies sold to unspecified persons” under the Payment Services Act, such that selling activities may not be undertaken unless registered as Cryptocurrency Exchange Services with the relevant local finance bureau.

The legal characteristics of ICO tokens must be reviewed on a facts-and-circumstances basis, so that they might be treated as Securities, or more specifically the Collective Investment Scheme, and be regulated under the Financial Instruments and Exchange Act of Japan.
