Blue Jays Sign Kazuma Okamoto

Japanese slugging third baseman Kazuma Okamoto and the Blue Jays are in agreement on a free agent contract, a source told MLB.com's Mark Feinsand. The club has not confirmed the news.
Okamoto was the biggest star of Nippon Professional Baseball's most storied franchise, the Yomiuri Giants -- Japan's version of the Yankees.
The 29-year-old, right-handed-slugging corner infielder was a six-time All-Star in Japan and a three-time home run king, leading NPB's Central League in homers in 2020, ’21 and ’23. Beginning with his breakout season as a 22-year-old in 2018, Okamoto posted six consecutive 30-homer seasons for the Giants, capped by a career-high 41 home runs in 2023.
Defensively, he can play either third base or first base, having won Golden Glove Awards in Japan at both positions -- two at third and one at first.
In 2025, Okamoto was limited to 69 games due to a left-elbow injury suffered in a collision with a batter running down the line while he was playing first base. But in those 69 games, he hit .327 with a .416 on-base percentage, .598 slugging percentage, 1.014 OPS, 15 home runs and 49 RBIs.
Over 11 seasons in NPB, Okamoto boasted a .277/.361/.521 slash line and .882 OPS, with 248 home runs and 717 RBIs.
Okamoto also starred for the Japanese World Baseball Classic team that won gold in the 2023 tournament. In seven games for Japan, Okamoto had a .333/.556/.722 slash line, 1.278 OPS, two home runs and seven RBIs. One of those home runs came against Kyle Freeland in Japan's win over the U.S. in the championship game.
Okamoto was one of three Japanese stars to be posted by their NPB club this offseason -- along with fellow superstar slugger Munetaka Murakami of the Tokyo Yakult Swallows and ace pitcher Tatsuya Imai of the Saitama Seibu Lions.
"I believe MLB is the best league in the world, and I’ve always wanted to play there," Okamoto said when the news that he would be posted was first announced in October. "I’ve worked hard with that goal in mind."
It's rare for the Giants to post their players, let alone a star in his prime like Okamoto. But they agreed to let Okamoto pursue a career in MLB in 2026.
Okamoto is the second Yomiuri star to come to the Major Leagues in the last two years, after longtime ace Tomoyuki Sugano did so in the 2024-25 offseason. But the then-35-year-old Sugano, who signed with the Orioles, was an international free agent by that point and not subject to the posting system.
The last time a Yomiuri Giants hitter of Okamoto's caliber jumped to the Major Leagues was when the legendary Hideki Matsui signed with the Yankees ahead of the 2003 season. Okamoto will try to follow in the footsteps of Matsui, who hit 175 home runs over 10 Major League seasons and was a two-time All-Star and the 2009 World Series MVP for New York.

Okamoto’s third base defense was strong enough to earn Golden Glove awards when playing with Yomiuri Giants in 2021-22, though he has played an increased amount at first base in the last three years. Scouts generally view Okamoto as at least a decent defensive third baseman at the MLB level, and his ability to also capably handle first base and left field adds to his versatility around the diamond.
Moreso than his glovework, however, Okamoto’s biggest plus is his bat. One of the top hitters in Japan for most of the last decade, Okamoto has hit .277/.361/.521 with 248 home runs over 4494 plate appearances with the Giants. He had a run of six straight seasons of 30+ homers from 2018-23 before dropping to 27 long balls in 2024, and he hit 15 homers with a .322/.411/.581 slash line over 314 PA in 2025 in a season interrupted by an elbow injury that cost Okamoto roughly three months of the NPB campaign.
A six-time NPB All-Star and a member of Japan’s World Baseball Classic-winning team in 2023, Okamoto is known for his ability to generate power while still making a lot of hard contact without many strikeouts. This approach fits right into the offensive gameplan that worked so well for the Jays in 2025. Blue Jays hitting coach David Popkins drew raves for his work in helping several Toronto hitters break out last season, and he could certainly aid Okamoto in making a smooth transition to MLB, perhaps particularly when it comes to adjusting to higher-velocity pitching. As noted by Fangraphs’ Eric Longenhagen, Okamoto has been inconsistent against higher-velo (94mph+) pitches, but he already showed improvement in this department in 2025.
The signing also represents a breakthrough for the Jays in their efforts to land a high-profile Japanese star. The Blue Jays’ attempts to sign Shohei Ohtani, Yoshinobu Yamamoto, and Roki Sasaki during the previous two offseasons were all thwarted by the Dodgers, which added some extra sting when all three players (particularly World Series MVP Yamamoto) contributed heavily to Los Angeles’ narrow win over the Jays in the Fall Classic.
While the Dodgers weren’t publicly known to be in on Okamoto, such teams as the Red Sox, Pirates, Cubs, Angels, Mariners, and Padres were all linked to his market. Earlier this afternoon, MLB.com’s Mark Feinsand indicated that San Diego “could be the frontrunner,” but instead it was Toronto who ended up sealing the deal.
