1. Ex Post Facto Regulations
1.1. Restrictions on business-to-business
transactions
In general, digital platformers have the discretion to decide
the conditions of the transactions with their counterparties;
however, their conduct may cause issues to arise under the Japanese
Antimonopoly Act ("AMA") if it artificially restricts
free competition in the market or if there is an unfair conduct
against the counterparty by using their relatively superior
position. For example, this may arise if the digital platformer
restricts the counterparty and only permits the counterparty to
deal with such digital platformer to the exclusion of other
competing digital platformers (restrictive trading, exclusive
dealing), or if the digital platformer otherwise unfairly
disadvantages the counterparty which is forced to use the digital
platformer's services by unilaterally changing the terms of the
contract therewith (abuse of a dominant position).
