The story
Former Yomiuri Giants coach Motoki Daisuke (54) attended the “Shigeo Nagashima Baseball School” held on October 31 in Sakura City, Chiba Prefecture, alongside Giants alumni Nakahata Kiyoshi (72), Makihara Hiromi (63), and Sadaoka Shoji (69). His Instagram post the following day showed him noticeably thinner than before — so much so that his uniform looked baggy on him — and fans quickly voiced concern. On 5ch, with other alumni his age or older looking robust by comparison, opinions split over whether this was simple weight loss or a sign of illness.

《How are you feeling? I’m a bit worried. Please show us your lively self on the field again.》

What people said
I can't tell who's in the first and third.
Isn't that Nakahata and Sadaoka?
Just don't do it with Mounjaro! (a diabetes drug also used off-label for weight loss)
Ramen, maybe?
now one punch would finish this guy off easy.
and compared to those three looking full of energy, there's Motoki at 54…
Losing weight like that at 54 is worrying.
His posture looks bad along with the weight loss, like he's actually losing muscle mass itself.
Could be something like diabetes or a hormonal disorder.
even the current players are all like 180cm/90kg.
he's probably not diabetic yet, just pre-diabetic.
He should watch his diet, but living a normal life shouldn't be a problem.
Even if it's not illness, losing this much weight means a middle-aged guy loses his power.
Coaching jobs basically have no days off.
Can he really handle traveling with the team for 143-plus games?
Sounds like he was trying to pull the line that tattoo artist made about "idiots love a ¥5,000 bill" — and it completely flopped. (reference to an old internet meme)
The Suiyoubi no Downtown shill brigade shows up everywhere lol
even elementary schoolers don't watch that show lol
things like limb amputation or blindness could follow.
I wonder if he's okay.
Well, he's probably getting good medical care,
so I'd guess he's fine.
Amputation only happens to people who really neglect it or never exercise.
Catch it before tissue death sets in and you're fine.
Same with blindness — deal with it as soon as something feels off and it shouldn't be an issue.
Exactly this.
When a middle-aged man or woman suddenly loses weight past 50, illness is the first thing you suspect.

…so why didn't he do that during his playing days lol
If he'd trained properly, he would've surpassed Matsui.
If we're going there,
he wouldn't have been overtaken by Matsui in the first place,
right?
Baseball → Motoki
Soccer → Narahashi
Sumo → Takanohana
Takanohana rebounded (gained every bit of it back) beautifully though lol
Narahashi naturally had a small appetite, but bulked up for his sport — once he retired and went back to eating normally, he slimmed down in no time.
Same deal as Minatogawa oyakata (a sumo stablemaster).
Background and Key Points of This Story
Motoki Daisuke was known during his playing days as a solidly built Yomiuri Giants infielder; since retiring, he’s worked as a TV commentator and head coach. 54 isn’t especially young on its own, but the contrast stood out because Nakahata Kiyoshi (72) and Sadaoka Shoji (69), who appeared alongside him at the event, have kept notably trim physiques despite their age. Thread commenters floated possibilities like diabetes or cancer-related cachexia, but these are purely speculation based on his appearance — neither Motoki himself nor the team has made any official statement about his health or condition. Some also pointed out the weight loss could simply be a healthy one, so it’s worth noting that losing weight doesn’t automatically mean serious illness.
