It’s been known for nearly a month now that NPB infielder Kazuma Okamoto is set to be posted by the Yomiuri Giants this winter, but a report from Nikkan Sports (Japanese language link) this morning provided a bit more specificity regarding Okamoto’s timeline. He’ll be officially posted tomorrow, on November 19th, and that will kick off a 45-day window for teams to negotiate with Okamoto, who is represented by Scott Boras of the Boras Corporation.
That’s the same posting date as right-hander Tatsuya Imai, a fellow Boras client. Boras told reporters (including those at Nikkan Sports) that the pair would follow the same approximate timeline. They’ll be posted tomorrow before traveling to the United States in early December. That sets them up to be in the country in time to begin negotiations with clubs ahead of this year’s Winter Meetings, which are set to run from December 7 through December 10 this year. The posting window for both Okamoto and Imai is set to end in early January, but it would not be a surprise to see the pair to sign before the holidays given the slowdown of activity around that time.
Turning back to Okamoto specifically, the 29-year-old is coming off a strong season in 2025 that was abbreviated by an elbow injury. While he only played in 69 games, he managed to slash .327/.416/.598 with 15 homers and 21 doubles in just 293 trips to the plate. He also showed strong contact ability and plate discipline with 11.3% strikeout and walk rates. That’s an unusually low strikeout rate by his standards, but even his 17.7% clip since the start of the 2018 season is nothing to scoff at. Impressive as Okamoto’s career .277/.361/.521 slash line in Central League play is, however, it’s worth remembering that NPB pitchers often lack the same high-end velocity that has become routine in MLB. Some scouting reports, including that of Eric Longenhagen of Fangraphs, have noted that Okamoto’s numbers suffer against mid-90s and higher velocity. Of course, that’s also a flaw that can improve with great exposure to those types of pitches.
Okamoto has spent plenty of time at both infield corners over the years, and there’s been some debate about his fit defensively in the majors. He’s generally viewed as more capable of sticking long-term at the hot corner than fellow infielder Munetaka Murakami, though it’s fair to expect some teams to view him as capable of being a regular at third while others see him as more of a first base only defender. Alex Bregman and Pete Alonso stand at the top of the third and first base markets, respectively, with Eugenio Suarez, Jorge Polanco, and Luis Arraez standing out among the other notable corner infield options available.
MLBTR predicted a four-year, $64MM deal for Okamoto at the outset of the offseason, though it’s worth noting there’s at least some reason to believe Okamoto, Imai, and Murakami could all outperform expectations financially, at least to some extent. Jeff Passan of ESPN reports that some MLB clubs are hoping to “avoid falling further behind” the Dodgers in the Japanese market, and that this sentiment could help the three top NPB talents coming over from Japan this winter secure better-than-expected deals.
The team that ultimately signs Okamoto will owe Yomiuri a posting fee on top of whatever they guarantee the infield. The posting fee works out to be 20% of the first $25MM Okamoto signs for, 17.5% of the contract’s next $25MM, and 15% of any money above the $50MM mark. If Okamoto were to sign for the $64MM guarantee MLBTR predicted he’ll land, the signing team would owe a posting fee of approximately $11.5MM, which would take the total financial outlay for Okamoto’s services to $75.5MM.

There are multiple reasons behind the lack of big free agent strikes. The Mariners’ infamous 10-year, $240MM deal with
