They apply to every registration, account activity, and use of betting and gaming features by users located in Japan. You must read and accept the Terms before placing any bet or using bonuses. If any part conflicts with local law, your local rules prevail and access may be restricted.

General Terms

    • You must not interfere with the website, app, or related systems, or attempt unauthorized access.

    • We may suspend or close accounts for suspected breach, fraud, chargeback, AML concerns, or inactivity. Balances will be handled according to these Terms and applicable legal requirements.

General Betting Rules

  • Who may place bets
    • Only eligible users who completed registration and verification may place bets. Users in Japan must be 20 or older and may bet only where such activity is allowed.
  • Bet acceptance and settlement
    • A bet is accepted when a ticket ID appears in your account history. Pending or failed transactions are not valid bets.
    • Markets are settled on the official result of the relevant event, as recognized by the governing body at the time of settlement. Later changes to results do not normally affect settlement.
  • Odds, stakes, and limits
    • Odds may change until acceptance. The system will accept the bet only at available odds at the time of placement.
    • Minimum and maximum stakes, as well as payout caps, are displayed on each market and may vary by event. Some markets or bets may be restricted for risk control.
  • Calculation of wins and losses
    • Returns are calculated as stake multiplied by the accepted odds, adjusted for any rule applicable to the market (for example, dead heat rules). Losses are limited to the stake on the bet.
  • Voids, cancellations, and errors
    • If an event is postponed, abandoned, or canceled, bets may be void unless specific market rules state otherwise.
    • If a palpable error occurs in odds, market, or settlement, we may correct the error and resettle or void the bet.
  • Betting restrictions
    • We may restrict, refuse, or limit bets on certain markets, events, or users for integrity, regulatory, or risk reasons.
    • Use of bonuses for bets is subject to specific wagering and market restrictions detailed in the promotion rules.

  • Integrity and conduct
    • Match fixing, misuse of insider information, and coordinated betting are prohibited. We may share relevant data with sports bodies or regulators when integrity risks are detected.

Responsible Gambling

  • Our approach
    • Betting should remain recreational. You should only risk money you can afford to lose and monitor the time and funds you spend on games and bets.
  • Account-level tools
    • Deposit, loss, and wager limits: set daily, weekly, or monthly caps.
    • Session time reminders and reality checks: prompts to help you track activity.
    • Time-out: take a short break from your account.
    • Self-exclusion: block access for a defined period or indefinitely. During exclusion, no new bets, bonuses, or deposits are permitted.
  • Self-assessment
    • Use the self-assessment checklist in your account to evaluate risk behaviors and decide whether to apply limits or exclusions.
  • Independent support in Japan
    • Prefectural addiction support centers provide counseling and referrals for gambling-related harm.
    • Gamblers Anonymous Japan offers peer-support meetings.
    • Local public health services and mental health clinics can advise on treatment pathways.
  • Safeguards for minors
    • Accounts are not available to persons under 20 in Japan. Use device-level controls and filtering tools to prevent underage access.
  • Our assistance
    • Support can help you set limits, implement self-exclusion, and provide information about resources available in Japan.
