On October 5, NPB’s executive committee — made up of all 12 pro baseball teams — approved loosening the color rules for bats, clearing the way for ‘colored bats’ starting next season. Under the current rule, bats are limited to just four colors: natural, dark brown, reddish-brown, and black. From next season, any single color will be allowed except white, silver, gold, and fluorescent shades. Japan banned colored bats outright in 1964, and the current four-color rule has been in place since 2005; next season will also see the return of Kawakami Tetsuharu’s ‘red bat’ and Oshita Hiroshi’s ‘blue bat.’ Over on 5ch’s ‘Giants Acting Manager’ thread, alongside this story, posters also jumped between Lotte’s Yamaguchi Koki and his monster home run, candidates for Samurai Japan’s generational shift, and Hiroshima’s Kozono Kaito getting cut loose.

Hagio should totally copy Satoteru's send-off too lol (nickname for a player)
18AnonymousOct 5, 2026 19:00
He's from the Negishi draft class
Back in Akita he was Yoshida Kosei's rival
21AnonymousOct 5, 2026 19:02
The one Lotte's putting up is Nishikawa Shiryu

Yamaguchi Koki (26, 8th year as a pro)
His OA (over-age) slot 1 is pretty much locked up, huh ()
25AnonymousOct 5, 2026 19:10
There's also Morishita, a slugger from the same generation
Question is which one gets priority
26AnonymousOct 5, 2026 19:12
Morishita already played in the WBC, so they probably won't send him this time (come to think of it, Maki getting picked last time was the unusual case) — don't you think?
27AnonymousOct 5, 2026 19:13

Honestly, I'd marry Kageyama Yuuka-chan in a heartbeat (idol/TV personality known as a big baseball fan)
29AnonymousOct 5, 2026 19:19
More likely he goes in as the 'experienced player' slot, like Maki did

Isn't it better to leave out anyone who already played in the WBC?
32AnonymousOct 5, 2026 19:24
Nah, they should actually send a few of those guys too
It helps to have experienced players around
33AnonymousOct 5, 2026 19:26
If they do send Morishita, it'd be in the OA slot (4th-year pro out of college)

NPB executive committee approves use of 'colored bats' starting next season — the legendary 'red and blue bats' set to return
https://news.yahoo.co.jp/articles/f099c99be3f6ea41f5d01514ec0d64ae1f8d9556
The Nippon Professional Baseball (NPB) executive committee, made up of NPB and all 12 teams, met in Tokyo on the 5th and approved the use of 'colored bats' starting next season. Under the current rule, bats are limited to four colors: natural, dark brown, reddish-brown, and black.
From next season, any color (single-tone) will be allowed except white, silver, gold, and fluorescent. Japan fully banned the use of colored bats in 1964, and the current rule has been in effect since 2005. Next season will also lift the ban on Kawakami Tetsuharu's 'red bat' and Oshita Hiroshi's 'blue bat.'
The committee had been in ongoing talks with the Japan Professional Baseball Players Association as well. Rules committee chairman Yamakawa Seiji explained the background, saying, 'There were requests to free up the use of various colors, out of respect for individuality.'

Let's free up spike colors too while we're at it, like MLB does

Well, it worked out in your team's favor too, so no complaints, right?

Lotte's been churning out power hitters nonstop — Yasuda, Yamamoto, Yamaguchi, Ikeda
That's the 'Aja' slot for you (slang nod to pro wrestler Aja Kong, used for someone built like a powerhouse)

Is there anyone in this thread who actually watched Kawakami and Oshita play in their prime, lol
50AnonymousOct 5, 2026 19:40
Re: #47
He retired back in Showa 33 (1958), so
you'd have to be in your mid-70s lol

Kanemura really doted on Kozono though

If he'd just taken the pitch it probably would've been a foul anyway — guess he prioritized racking up the out
Background and talking points on this story
Colored bats were banned outright in 1964, and even the 2005 rules kept things limited to four colors — natural, dark brown, reddish-brown, and black. With this approval, anything other than white, silver, gold, or fluorescent is now fair game, meaning Kawakami Tetsuharu’s famous red bat and Oshita Hiroshi’s blue bat are, at least on paper, making a comeback. There was little objection to the rule change itself in the thread — the conversation mostly drifted toward calls to free up spike colors too, MLB-style, and musing that anyone who actually remembers Kawakami and Oshita playing in their prime must be in their mid-70s by now. At the same time, the same thread was running several other storylines in parallel — Yamaguchi Koki’s home run pace, candidates for Samurai Japan’s generational turnover, debate over the Climax Series advantage rule — a reminder that this is less a reaction to one piece of news than NPB’s usual daily chatter thread.
