Betting Profit: J2-League

This page will show you how profitable betting on the J2-League in Japan has been over the past 18 months. The page places £10 bets on every market using pre-match and peak in-play odds from Bet365 and shows you the long-term results and profitability — including what you could have won betting in-play at the best available odds.

How does "With Alerts" work?

During a match, odds drift as the game unfolds. If Man City are 1.40 pre-match and it's 0-0 at 60 minutes, the odds might drift to 2.00. With OddAlerts, you'd get a notification when the odds increase past your threshold.

The alert threshold determines how much the odds need to move before you bet:

  • +10% — 2.00 → triggers at 2.20. More bets, smaller edge.
  • +25% — 2.00 → triggers at 2.50. Good balance.
  • +50% — 2.00 → triggers at 3.00. Fewer bets, bigger odds.
  • +100% — 2.00 → triggers at 4.00. Only major drifts.

You only bet on games where the alert actually fires. Games where odds don't move enough are skipped entirely.

How is profit calculated?

Pre-Match: £10 bet on every game using closing Bet365 odds.

With Alerts: £10 bet only on games where in-play odds drifted past the threshold. You bet at the trigger price. Games that didn't trigger an alert are not counted.
