The league consists of two separate divisions, B1 and B2, so there are always two champions, and double the betting options. B1 hosts 20 teams, and B2 has 16 teams, which also follow a system of promotion and relegation between the two divisions. Each division is further broken down into Eastern and Western Conferences. 

B1 plays a 60-game regular season that consists of 36 games against teams in their own conference, and then 24 games against teams in the other conference. Eight teams with the best records head to the playoffs, which consists of the best of three series in the quarter-finals, semi-finals, and finals.

How to Bet On Japan B League Odds

Japan B.League Betting: A Variety of Wagering Options

When it comes to betting on the Japan B.League, you are in luck because here at BetUS Sportsbook, we have a great selection of odds and lines for you to take advantage of. Let’s start by going over the types of Japan B.League bets you can place on our sportsbook.

Moneyline betting on the Japan B.League is exactly like any other moneyline on any other sport. You are choosing which team you believe will win the game outright. You don’t have to do much more than that – simply need to pick a winner.

Point spreads for the Japan B.League will be listed and teams on either side will be assigned a spread. The favored team will have to win the game by more than the number listed, and the underdog will have to win or lose by less than that number of points assigned.

Totals bets or over/under bets are options that allow you to bet on the total number of points scored by both teams but added together. The number will be high, as all basketball totals are, but it’s the total number of points scored by two teams, so you will need to decide if you think the teams will score more or less than that number.

There won’t be a wide variety of prop bets on the regular season games for either division, options like you’d find in North American sports, but you can find some fun props for higher profile games. These bets are placed on outcomes that have nothing to do with the final score or who wins the game.

Futures betting allows you to place a wager on which team will win each of the championship titles. Both B1 and B2 will have their own oddsboard with each team listed in order from most likely to least likely and will have odds assigned. You can bet on a team’s odds to win their championship title early in the year.

If you think you have everything you need to bet on the Japan B.League odds, you should head over to the sportsbook to check out what odds and betting lines are available. If you need more help or more resources, our How to bet on Sports guide will be a great learning curve for your betting needs.
