When School Milk Came in Glass Bottles: Showa-Born 5channers Get Nostalgic

The story

A thread on 5ch’s “Nandemo Jikkyō G” board about school lunch milk once being served in glass bottles sparked a wave of nostalgia from people born in the Showa era. Commenters piled on with memories of how they used to open the caps — prying them off with a fingernail, or using a special pick — and of collecting the lids to play “pokkon” (a flipping game using milk-cap lids), showing that bottle shapes and games varied by generation and region. Meanwhile, the claim that “bottled milk tastes better” got some pushback from people pointing out that “the contents were the same,” turning into a minor debate.

Elementary school had paper cartons
Middle school had bottles
That cold rim on the bottle mouth was the best

You collect the lids.

Re: #5
Somehow you'd end up with lids from milk you never even drank lol
6AnonymousOct 11, 2026 23:28
I don't know why, but bottled milk just tastes better.
7AnonymousOct 11, 2026 23:28
Wait wait wait wait! How do you even open the cap?! 😨

You scratch it open with your fingernail

It's just got a paper lid on top

There's a special pick for it

That weird game where you blow on the lid to flip it over
13AnonymousOct 11, 2026 23:31
I used to play menko with the caps 🥺

If it had a cow drawn on it, that's mine too

Re: #15
This looks lukewarm and nasty, how was it?
16AnonymousOct 11, 2026 23:32
I used to bring my own can opener from home and pop it open with a "shupon" (the sound of a bottle opening)
19AnonymousOct 11, 2026 23:35
I'm a Heisei kid and it was normally bottles too, just saying
20AnonymousOct 11, 2026 23:35
The guy who tries to open the bottle lid with his nail and only manages to peel off the paper surface
22AnonymousOct 11, 2026 23:35
Back in the day, guys who could pop the bottle open with a karate chop were popular with the girls
24AnonymousOct 11, 2026 23:36
We used to collect the pokkon lids, lay out dozens of them on the floor, then slam an upside-down indoor shoe down next to them — however many flipped over from the gust of wind, you got to keep
25AnonymousOct 11, 2026 23:36
Making menko out of the caps, or poking two holes near the center and threading string through to make a spinning toy — it's kind of sad Heisei and Reiwa kids never got to experience that.
Don't tell me you've never even made a string-spinner out of a film canister either?
26AnonymousOct 11, 2026 23:36
Once you're a middle-aged guy, milk gives you diarrhea! Tough luck!
27AnonymousOct 11, 2026 23:37
Mine was a bottle but with a plastic cap, so I never got the whole "collecting the lids" thing
28AnonymousOct 11, 2026 23:37
Re: #21
Not ice-cold, but cold enough — enough to get condensation on the surface
29AnonymousOct 11, 2026 23:38
That tool you'd stick in and twist to pop the lid off using that principle — I bet it goes for a premium price now

Lol, Omigawa Milk

You guys had school lunch on Saturdays?
Ours were half-days
44AnonymousOct 11, 2026 23:43
Re: #41
Nah, Saturday was just 2 hours, but we'd drink milk or orange juice on the way home
Is that just a thing in my area?
57AnonymousOct 11, 2026 23:55
That frustration when the paper lid peels off thin and won't come off cleanly
61AnonymousOct 11, 2026 23:59
Re: #57
You stab the edge with your chopstick
84AnonymousOct 12, 2026 00:16
This guy would lose it if they switched to cartons
85AnonymousOct 12, 2026 00:16
Bottled milk was delicious.
Paper cartons, plastic bottles, all that plastic stuff — gross.

Re: #85
Sorry to say, the contents were the same

It's not pathetic because you're Showa-born, it's pathetic because you're still telling stories about elementary school
106AnonymousOct 12, 2026 00:40
Re: #102
It's both, honestly
103AnonymousOct 12, 2026 00:39
I know some places still use bottles, but what do they seal them with now?

Re: #103
A plastic lid
There's a little string-like tab you pull to open it

Background and Key Points of This Discussion

School lunch milk being served in glass bottles was mainly a Showa-to-early-Heisei phenomenon; glass milk bottles were gradually phased out in favor of paper cartons and plastic containers due to environmental impact, cost, and breakage risk. What split the thread was that even among people who grew up with glass bottles, there were two camps — the “paper lid” crowd and the “plastic cap” crowd — showing how much container shapes varied by region and generation. The “pokkon” (menko-style) lid game and the shared struggle of prying caps open with a fingernail became common ground everyone bonded over, but on the question of taste, some pointed out that “the contents were the same,” suggesting the idea that bottled milk tasted better may largely be a trick of nostalgia. It’s also worth noting that some schools still serve bottled milk today — the switch to paper cartons was never total.
