Three former NBA players, Yuta Watanabe, Sekou Doumbouya, and Stanley Johnson, are thriving in the B.League in Japan and have rebuilt their value enough to warrant another opportunity on an NBA roster.
While the path to the NBA was once a narrow, one-way street, the modern basketball landscape has evolved into a sprawling global web.
Japan’s B.League, once seen as a quiet retirement destination for veterans, has turned into a league where players can revive their careers.
It is now a place where former first-rounders and experienced players go not to disappear, but to reinvent themselves under the bright lights of a basketball-obsessed nation.
Here are the top three Japanese League players who belong back on an NBA roster right now.

Watanabe is the superstar of Japanese basketball. His return to the Chiba Jets in 2024 was the biggest domestic signing in B.League history.
Through 44 games in the 2025-26 season, he is averaging 13.0 points, 4.8 rebounds, and 1.9 assists for the Jets.
The 31-year-old wing is still in his prime and has transitioned seamlessly from a role player in the NBA to a franchise cornerstone in Chiba, proving he can handle the physical toll of being a primary defensive stopper while maintaining his efficiency as a high-volume shooter.
Why Yuta Watanabe belongs in the NBA
In the NBA, Watanabe carved out a niche as a premier 3-and-D specialist.
Across 213 games with the Grizzlies, Raptors, Nets, and Suns, he proved he could provide elite spacing – a skill highlighted by his 44% shooting from deep during the 2022-23 season.
His impact extends to the international stage as well, where he averaged 11.7 points and 6.3 rebounds at the Paris 2024 Olympics, 14.8 points and 6.2 rebounds at the FIBA World Cup 2023, and 17.7 points and 8.0 rebounds at the Tokyo 2020 Olympic Games.
His basketball IQ and ability to excel within a system without over-dribbling make him a plug-and-play asset for any contender – similar to the value Luke Kennard currently provides to the Los Angeles Lakers.
NBA comparison: Sam Hauser, Royce O’Neale, or Caleb Martin. Like Hauser, Watanabe provides high-level movement shooting and disciplined team defense. Reason for B.League stint: Purely personal and financial. According to Donatas Urbonas of BasketNews, Watanabe’s contract is estimated at nearly $5 million post-tax, which rivals the NBA’s average salary ($12M pre-tax) in net earnings, all while playing as a superstar in front of his home fans and prioritizing his mental well-being.

The 15th overall pick in the 2019 NBA Draft is finally becoming the player scouts envisioned when he was a teenager in France.
Still only 25 years old, the French-Guinean forward has transformed into one of the B.League’s most dominant offensive forces for the Koshigaya Alphas.
After a period of stagnation in the NBA where he was often the youngest player on the floor, Doumbouya has used his time in Japan to shed the “project” label.
By displaying a significantly higher motor, a matured frame, and a refined post-game, he has been able to punish smaller wings while averaging 18.7 points and 7.3 rebounds per game.
Why Doumbouya belongs in the NBA
Doumbouya’s NBA exit was largely due to a lack of polish and consistency.
In Japan, he has been forced to be “the guy,” developing a shot-creation profile he never had with the Detroit Pistons.
His physical tools – 6’9″ with a massive wingspan (6’11”) and fluid athleticism – remain elite and are currently rare even by NBA standards.
In recent overseas stints, Doumbouya has shown an improved 3-point stroke (nearly 30% on high volume) and the defensive switchability to guard pretty much every position on the court.
NBA comparison: A more athletic Jarred Vanderbilt or Precious Achiuwa. Reason for B.League stint: Development. He was too raw for the NBA at 19; at 25, he is now using the B.League to prove he can handle high usage and consistent professional responsibility. He is essentially doing his “senior year of college” on a professional stage.

The 8th overall pick in the 2015 NBA Draft has become an absolute sensation for Nagasaki Velca.
Known as a “LeBron stopper” early in his career for his stout defense, Johnson has unlocked a level of offensive production in Japan that has gone viral multiple times this season.
Before moving to the B.League, Johnson showed he was still far too good for the minor leagues, dominating the 2024-25 G League with the South Bay Lakers, where he averaged 15.2 points, 6.5 rebounds, 4.7 assists, and 1.4 steals.
This momentum has carried into Japan, where the 29-year-old is now a legitimate MVP candidate for league-best 35-9 Nagasaki: 23.0 points (34.4% 3PT), 6.1 rebounds, and 3.8 assists over 43 games.
Why Johnson belongs in the NBA
Johnson has always been an NBA-caliber defender with a frame built for the modern positionless game.
While poor shooting and offensive efficiency were previously the main criticisms against him, he is now shooting nearly 35% from three on significant volume, 45% from the field, and over 80% from the free-throw line with Nagasaki.
An NBA team looking for a point-forward who can guard the opposing team’s best player and still space the floor would find him valuable as an 8th-12th man in the rotation.
NBA comparison: Matisse Thybulle or Jae Crowder. Reason for B.League stint: Market reset. After bouncing around on short-term NBA contracts and the G League, Johnson chose to go overseas to prove his offensive game had caught up to his elite defensive floor. He is proving he can be an efficient scorer rather than just a defensive specialist.
Pijus Sapetka began his basketball media career in 2021, building on years of closely following the sport. Since then, he has reported from a variety of basketball events, including the EuroLeague Playoffs, Lithuanian Cups, LKL Finals, EuroCup games, the FIBA Olympic Qualifying Tournament, and Goran Dragic’s Farewell Game. He holds a degree in Journalism & PR.
