Esports Tournament Operations Require Separate Analysis of Prizes, Sponsors, and Minors

Hello! I am Noriaki Asato, representative attorney of Legal Agent.

More companies are organising esports tournaments, game events, streamer competitions, and online community tournaments.

Once an event involves sponsors, prize money, streaming, ticket sales, merchandise, influencers, minors, or overseas participants, the legal issues become extensive.

An esports tournament is not simply an event-management project. Under Japanese law, organisers may need to consider the Act against Unjustifiable Premiums and Misleading Representations, gambling offences, payment-services regulation, copyright, image and publicity rights, sponsorship contracts, minors, personal information, and platform rules together.

Determine the legal character of prize money

Prize money is often the first issue raised in an esports tournament.

The organiser should determine whether the prize constitutes a regulated premium under Japanese advertising law and whether the structure raises concerns under the gambling provisions of the Penal Code.

A structure in which participants pay entry fees that fund a pool distributed according to wins or losses requires particular care. The analysis may differ where a sponsor supplies the prize for advertising purposes and the event is designed as a genuine skill-based competition.

The Consumer Affairs Agency explains that, depending on the facts of the individual event, a prize recognised as remuneration for work or performance is not a regulated premium. In practice, the organiser should document the competitive nature of the event, the participant-selection process, the source and purpose of the prize, and the relationship between entry fees and prize funds. Even where advertising regulation does not apply, the gambling analysis remains separate.

Clear the rights needed to use the game and related material

An esports event uses copyright-protected material owned or controlled by the game publisher.

The relevant material may include game footage, characters, music, logos, commentary streams, thumbnails, archives, and subsequent clips or promotional use.

Where the publisher has issued tournament or streaming guidelines, the organiser should confirm that the event falls within their scope and conditions. Commercial tournaments, sponsored streams, paid tickets, prize competitions, and merchandise may require individual permission.

For each title, the organiser should therefore check tournament permission, streaming, sponsor restrictions, prize limits, archive use, and the treatment of user-generated footage before announcing the event.

Control sponsorship terms and advertising disclosures

Sponsor exposure is central to many esports events.

This may include logo placement, on-stream messages, endorsements by participants, social-media posts, promotional goods, campaigns, and coupons.

The sponsorship agreement should define the promised exposure, placement, duration, prohibited claims, category exclusivity, crisis response, cancellation rights, and the rules governing posts by players and streamers.

When a player or streamer introduces a sponsor's product, the organiser should also confirm that viewers can readily recognise the commercial relationship. In Japan, advertising that appears to be an independent third-party statement may fall within the rules on undisclosed advertising where the advertiser was involved in determining the content.

Build specific safeguards for minors

Minors frequently participate in esports events.

The rules should address registration, prize receipt, appearance and streaming, image rights, personal information, travel and accommodation, and communication with schools or parents.

For participants under 18, particularly where a substantial prize or lengthy broadcast is involved, the organiser should establish a reliable process for legal-representative consent, identity verification, safety management, and retention of the consent record.

Additional consumer-protection analysis may be necessary if the event combines participation by minors with in-game purchases, loot-box mechanics, or promotional campaigns.

Distinguish a one-off tournament from a permanent venue

The analysis may change if the business operates a permanent venue equipped with game machines or similar amusement equipment and allows customers to play there.

Depending on the equipment and the actual operating model, the venue may raise licensing questions under the category-five amusement-business provisions of Japan's Act on Control and Improvement of Amusement Business. Before opening, the operator should organise the fee model, equipment, premises, opening hours, and customer use and consult the local police authority.

Conclusion

Esports operations require separate workstreams for prize money, game rights, sponsorship, advertising disclosures, minors, streaming rights, and personal information.

Legal Agent assists with tournament rules, game-event planning, streamer and sponsorship agreements, streaming terms, prize structures, and safeguards for minors. The more ambitious the event, the more important it is to complete rights clearance and operating rules before promotion and registration begin.
