The story

Masumi Kuwata, who stepped down as manager of the Yomiuri Giants’ farm (ni-gun) team last October, revealed the circumstances behind his departure on a radio program aired August 30. According to Kuwata, the team had told him during the Miyazaki Phoenix League that they wanted him back next year, only to suddenly tell him to hang up his uniform, giving an explanation to the effect of “it’s hard to work with me around.” On 5ch, users pointed to friction with the farm team’s general manager at the time, while others speculated Kuwata could end up managing another team next season. Reactions especially focused on his name coming up as a candidate for the DeNA BayStars job, with the discussion spreading to his relationship with Kazuhiro Kiyohara and the Giants’ tendency to favor homegrown talent.

Masumi Kuwata, who abruptly stepped down as the Giants’ farm team manager last fall, has revealed the details behind his departure on a radio show. His candid remarks about internal team relationships and coaching philosophy have sparked surprise both inside and outside the baseball world. While some Giants fans are now calling for him to become next season’s manager, the possibility of him taking charge of another club is also gaining real traction.

Masumi Kuwata explains why he left the Giants

Appearing on the radio program “Ikushima Hiroshi’s Sunday at 9” on August 30, Kuwata explained his reasons for leaving the Giants last October.

So he betrayed Kiyohara, and now the Giants betrayed him?
4AnonymousSep 4, 2026 09:34
I always figured Kuwata and the Giants were on bad terms already — guess not?
6AnonymousSep 4, 2026 09:35
The record for most home runs by a rookie in a season is held by Kiyohara and Kuwata.
7AnonymousSep 4, 2026 09:35
To today's players he's basically nothing more than "some guy named Matt's dad" at this point.

This, so true.
8AnonymousSep 4, 2026 09:36
The Giants probably would've let him manage if he hadn't gone to MLB in the end.
Time to finally ditch that old tradition.

Re: #8
Sugano and Okamoto both went to the majors too.
After Sakamoto, there's really no talent left.

Re: #8
I'm dying for Matsui to become manager — does MLB experience even matter?
13AnonymousSep 4, 2026 09:39
Re: #1
Want him as Shinjo's successor.
We need a manager who's moved on from old-guard spirit-based baseball to modern theory.
14AnonymousSep 4, 2026 09:39
I just can't picture Kuwata as a "Giants for life" type.
18AnonymousSep 4, 2026 09:40
So Matt's the one who cut him loose from all that baggage, huh.
19AnonymousSep 4, 2026 09:40
A guy you don't want to get tangled up with —
worse than Kiyo (Kiyohara).
21AnonymousSep 4, 2026 09:40
The moment he suddenly started trash-talking, I figured that meant no offer for next season had come in.
22AnonymousSep 4, 2026 09:41
It wasn't FLASH, it was Josei Jishin (a Japanese weekly tabloid magazine).

Re: #22
Oh, Shukan Josei ("Weekly Woman") — my mistake.
33AnonymousSep 4, 2026 09:44
Well, there are plenty of other candidates, so it probably won't come around to Kuwata.
56AnonymousSep 4, 2026 09:54
Re: #33
There really isn't anyone else. Going by the "pure Giants blood" rule and requiring ace-pitcher or cleanup-hitter caliber, it's basically just:
Hara (cutting it close age-wise)
Abe, Takahashi, Saito Masaki, Sakamoto
and that's about it.
34AnonymousSep 4, 2026 09:45
Oisix will probably get its own first-team squad eventually —
and when that happens, wouldn't Kuwata be the manager?
35AnonymousSep 4, 2026 09:45
He said it was hard to work with Kuwata around —
well, now Abe's gone from the Giants too, lol.
39AnonymousSep 4, 2026 09:47
Re: #35
If Kuwata had stuck around, wouldn't it be him running things instead of Hashigami?
51AnonymousSep 4, 2026 09:52
Re: #35
Then come back already.
37AnonymousSep 4, 2026 09:47
Farewell, Masumi Kuwata. Farewell, pro baseball.
40AnonymousSep 4, 2026 09:47
They picked eel over Kuwata and still got betrayed, lol.
42AnonymousSep 4, 2026 09:49
DeNA gets Kuwata, and the Fighters get Daisuke Matsuzaka, huh.
43AnonymousSep 4, 2026 09:49
Japanese sports have improved a lot since ditching all that spirit-based mentality.
46AnonymousSep 4, 2026 09:50
Re: #43
Back in the Showa era they used to glorify stuff like training through injuries or playing with a broken bone — things that, in hindsight, you should never actually do.
69AnonymousSep 4, 2026 09:59
Kuwata's clearly a stubborn guy.
Even from the outside you can tell, so of course that's how it'd play out on the inside.
72AnonymousSep 4, 2026 10:00
Re: #69
Sounds like he just didn't see eye to eye with Abe.
He's the blunt, say-it-like-it-is type after all.

Komada was let go for the exact same reason, at the exact same point during fall camp —
so the real answer is that Abe was the problem, not Kuwata.

Background and Key Points of This Story

Kuwata was the ace pitcher of the famous “KK Combo” alongside Kazuhiro Kiyohara, and the two joined the Giants together after starring at PL Gakuen high school. After retiring, and following a stint in Major League Baseball, he took on a coaching role with the Giants’ farm team. The term “Oh Sadaharu path” refers to the precedent of Giants-bred figures going on to succeed as managers of other teams, and the same possibility is now being floated for Kuwata. Opinions in the thread were split between those praising his theory-driven, non-spirit-based coaching style, and those who felt his blunt, say-it-straight personality tends to create friction within an organization. Some posts also pointed to a former player who was let go at the same point in fall camp for the same reason, raising questions about the Giants’ farm-team system itself. It’s worth noting that the account of his departure comes solely from Kuwata’s own remarks, and the team has not issued any official explanation.
