Japan B League


The Japan B League is the professional men’s basketball league in Japan. The league is fairly new, after only being founded in 2016, and falls under the FIBA Asia confederation. The B.League is governed by the Japan Professional Basketball League. 

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 to 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 best of three series in the quarter finals, semi finals and finals.

How to Bet On Japan B League Odds

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 the 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 the 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.

Rolling If Bets (RIF) allow you to use the balance (amount) from existing wagers to make a new wager. As long as existing wagers have not been graded, the amount wagered can still be used to make new wagers. However, if your original wager loses, the Rolling If Bet is then cancelled. There are two options for ties (pushes); you can specify if you want the Rolling If Bet to continue in case of a tie or simply cancel the RIF.

Rolling If Bets are:
  • only allowed on straight bets, Parlays and Teasers.
  • not available with Free Plays or Futures and Props
  • only available if you have pre existing, non graded wagers
  • you can only use the funds from the amount of the pre existing wager
How to Place a Rolling If Bet:
  • Choose any straight, parlay or teaser and Place it on the Bet Slip
  • Click on the Rolling If Bet button next to the wager detail
  • In the RIF dropdown, choose a wager that you want to use for RIF
  • Click on "If Win Only" or "If Win or Push" (explained above)
  • Fill in the amount and confirm your wager (the system will not allow you a higher amount than what is available)
