Kuwata’s Exit as Giants Farm Manager Chalked Up to ‘Failed Player Development’ — 5ch: ‘Kuwata’s Just Not Cut Out for Coaching Prospects’

From our other sites

The story

It’s been reported that the Giants front office judged Kuwata Masumi’s tenure as farm team manager a case of “failed player development,” prompting his departure — despite the farm squad finishing first in the Eastern League in team ERA, batting average, and stolen bases. The report also touches on rumors of friction with former first-team manager Abe Shinnosuke. On 5ch’s Giants threads, the news set off a wave of doubts about Kuwata’s development skills, and comments from his successor, new farm manager Ishii Takuro, who let slip “No, I’m exhausted” in a solo interview, also became a talking point. Meanwhile, the first team is in the final stretch of the pennant race, two games behind the first-place Tigers with four games remaining, and surrounding news — like Kazuma Okamoto’s rookie MLB season wrap-up and the Carp’s Sasaki pulling out due to illness — was also circulating.

Turns out there were a lot of Giants fans among iLife otaku (fans of "iLife") — especially the women.

Carp's Sasaki out sick, to miss the Sept. 28 game — not removed from the active roster; had started 48 straight games since late July

Guess there's no game today?
If the Tigers ('Chin,' a common 5ch nickname) aren't playing either, that's a bummer.

Could be fun watching whether soccer can pay off baseball's debt (make up for baseball's loss).

Every guy Kuwata sent up to the first team last year turned out useless, but most of the guys 'Tonro' (a mocking nickname for a staff member) sent up this year were actually decent.
Kuwata's just not cut out for player development.

Re: #42
Right? I just wish he'd stay out of it entirely at this point.
47AnonymousSep 28, 2026 17:47
If the BayStars are starting Azuma today, that means on 4 days' rest it won't be us next, right?
If it's 5 days' rest against the Tigers, there's still a chance for a comeback title.
48AnonymousSep 28, 2026 17:48
Probably 'Unagi' (eel — a nickname, apparently for someone on the coaching staff) was the one vetoing the players Kuwata wanted to call up lol
49AnonymousSep 28, 2026 17:49
Like Takuro (Ishii) said,
the acting manager actually plays guys as soon as he calls them up — total opposite of Unagi.
51AnonymousSep 28, 2026 17:53
Unagi used to play them plenty too though.
It's not really the total opposite.
52AnonymousSep 28, 2026 17:54
Forget not playing them — they didn't even get called up in the first place.
53AnonymousSep 28, 2026 17:54
Higashi (Azuma) was giving a press conference earlier, and the way he talked reminded me of that show about roster-cut notifications.
54AnonymousSep 28, 2026 17:54
Being under a .500 mark in the farm league is simply inexcusable at this point.
55AnonymousSep 28, 2026 17:55
Hashigami calls up even guys who don't need to be there.

[Roster Cut Notification Periods]
First notification period: Sept. 28 – Oct. 9
※For teams eliminated in the Climax Series First Stage, the day after elimination (or the day after that, if travel is involved)

Second notification period: The day after the Climax Series ends through Oct. 30

※Notification period for development-contract players: Sept. 28 – Oct. 31

Hamastar's really gone dark already at this hour, huh.
61AnonymousSep 28, 2026 17:57
Think about it rationally —
two games behind the first-place Tigers with only 4 left,
it's already over.
65AnonymousSep 28, 2026 17:59
We'll win the head-to-head matchup, so it's effectively just a 1-game gap.
77AnonymousSep 28, 2026 18:05
Kikuchi's got 2,000 career hits and they still make him bunt — poor guy.
80AnonymousSep 28, 2026 18:07
Playing baseball like this, the Carp really have no shot at climbing back, do they.

Background and Key Points of This Story

Kuwata Masumi was once a star ace for the Giants, and after retiring he served as pitching coach and in other roles before taking over as farm team manager this season. The fact that his departure came despite the farm squad finishing first in the Eastern League in team ERA, batting average, and stolen bases has drawn attention to the gap between the on-paper numbers and the front office’s “failed player development” assessment. Reports of friction with former manager Abe Shinnosuke have also surfaced, suggesting the evaluation may have hinged not just on results but on how well he coordinated with the first team and its player-usage philosophy. While many thread comments question Kuwata’s development chops, some also praised his successor, new farm manager Ishii Takuro, for how quickly the first team uses players once they’re called up — suggesting that how well a farm system runs depends not only on the manager’s own ability but on how it meshes with the first team’s usage policy. Meanwhile, as of September 28 the first team sits two games behind the first-place Tigers with four games left in a tight pennant race, and the farm-management story was unfolding alongside that tension.
