Rui Hachimura Trains With Sumo Wrestlers in Japan — Prepares for Most Physical NBA Season Yet
In an unexpected and powerful twist to his offseason training, Los Angeles Lakers forward Rui Hachimura has taken his preparation to new extremes — by training with elite sumo wrestlers in his native Japan. The 6-foot-8 power forward, known for his strength and versatility, has reportedly spent the last three weeks immersed in sumo culture, undergoing daily sessions with top rikishi (sumo athletes) at a private stable in Tokyo.
This unconventional training method is more than a publicity stunt — it’s a calculated move. Hachimura, now entering what many believe will be a breakout season, has made it clear: he’s determined to become one of the most physically dominant forwards in the league. Sources close to the player say he’s added nearly 10 pounds of muscle since the start of summer, much of it developed through the intense pushing, grappling, and resistance work unique to sumo.
“These guys are different,” Hachimura said in a brief video shared on his social media. “It’s not just about size — it’s about balance, core strength, discipline. I’m learning things I never worked on before. This will change how I play.”
Witnesses say Hachimura participated in real sumo drills — including “shiko” (leg stomps for hip flexibility), “teppo” (repetitive slamming against wooden poles to build upper body strength), and even live bouts with lighter division rikishi. He also followed a modified sumo diet, incorporating the famed chanko-nabe, a protein-rich stew designed to fuel extreme training.
NBA performance coaches are reportedly intrigued. While most players stick to traditional weightlifting, cardio, and on-court skill work, Hachimura’s hybrid regimen could give him a unique edge. The NBA has become faster and more physical, especially at the forward position, where players are expected to guard everyone from bruising bigs to twitchy wings. Hachimura’s sumo-inspired balance, leverage, and explosion could become a nightmare matchup for opposing teams.
“He’s always been strong,” said a Lakers insider. “But now he’s playing with low leverage, body control, and core power like we haven’t seen before. He’s hard to move, and he’s even harder to stop.”
The Lakers front office has also taken note. With a renewed focus on defense and physicality heading into the new season, Hachimura’s growth could elevate his role on the team. While he was a reliable bench piece last year, sources suggest he could be in contention for a starting spot — particularly if he continues to demonstrate this new physical edge during training camp.
For Hachimura, though, it’s not just about individual performance — it’s about honoring his roots. “Sumo is a part of Japanese culture,” he said. “It’s an honor to train with these guys. They’re legends in their own sport. And I want to carry that power with me onto the NBA court.”
As preseason looms, all eyes will be on Hachimura. Will the ancient discipline of sumo translate into modern NBA dominance? One thing is certain: he won’t be pushed around — on or off the court.
