I don't even remember my school having a cultural festival….
8AnonymousSep 27, 2026 11:44
Damn, that's impressive.
They're just students — can't have had that big a budget.

Re: #1
This is amazing.

Last year's Western-style one was kind of meh, but this year's was worth seeing.
11AnonymousSep 27, 2026 11:46
Does a school cultural festival really have an 'entertainment/sports' angle? (poking fun at this being posted on 5ch's Geinou/Sports board)
16AnonymousSep 27, 2026 11:48
Doing this out of cardboard….

Re: #16
If it's a 'Danborghini' (a famous cardboard-supercar builder), sure…
20AnonymousSep 27, 2026 11:49
I figured it'd be some simple 2-3m thing, but this is amazing.
Wonder how much it cost to build.
24AnonymousSep 27, 2026 11:50
Why do Urawa High School threads keep popping up on this board?

Re: #1
Too good to just throw away.
Ship it off to Nikko Toshogu (the shrine housing the real gate).
35AnonymousSep 27, 2026 11:55
Going this far makes you wonder about safety, but since it's high schoolers doing it, the conclusion is basically 'as long as it doesn't collapse, it's fine for now.'

Re: #35
Yeah, that is a bit worrying.
Maybe it's cardboard, so it's lightweight lol
116AnonymousSep 27, 2026 12:20
Re: #112
Less worried about it breaking, more worried about it
toppling over and crushing someone underneath.
Also arson.
117AnonymousSep 27, 2026 12:20
Re: #112
Given how massive this thing looks, even if it were a 'Danborghini'-style build, not sure that'd save you.
49AnonymousSep 27, 2026 11:59
What's amazing about Urawa High is that they do this with exam prep on the back burner.
Even the day before the Center Test (the old national exam), third-years were practicing like their lives depended on it just to beat the teachers' team in the school rugby tournament.

Re: #49
Their Tokyo University acceptance rate isn't even that great these days, so it feels backwards.

Urawa High School's university placement record

Re: #69
The Tokyo University of the Arts (Geidai) numbers are impressive.
150AnonymousSep 27, 2026 12:30
Re: #69
Guess not many of them go abroad.
71AnonymousSep 27, 2026 12:07
They put this much effort into a cultural festival?
I thought festivals were just classroom haunted houses or cafes, that level of thing.
78AnonymousSep 27, 2026 12:08
These days you can have AI whip up the blueprints, so they can pour all their effort into the manual work.
Even so, this is amazing.
That dragon alone — how many hours would that take someone?
83AnonymousSep 27, 2026 12:11
Re: #78
I think they're using a 3D printer. Apparently there's a tradition of spending a whole year building the gate.
84AnonymousSep 27, 2026 12:11
They must be busy studying — how much time did they actually sink into this?
87AnonymousSep 27, 2026 12:12
Re: #84
Prefectural Urawa has a high rate of students taking a gap year to re-study (ronin), so I guess the studying happens after graduation.
95AnonymousSep 27, 2026 12:14
It's impressive that nobody's going 'eh, it's probably just AI' about this one.
101AnonymousSep 27, 2026 12:16
Re: #95
Come on, at least know what a 3D printer is.
102AnonymousSep 27, 2026 12:17
Re: #95
I bet AI or alumni (OB) are involved in the design — you can tell by looking at the gates from past years.
Teacher involvement is 100% for sure, but their enthusiasm seems to vary.

(Prefectural) Urawa High School

Hensachi (deviation score): 73
Ranked 9th nationally among all-boys high schools by hensachi (2nd among public schools)
Won the 'High School Quiz' championship three times (2005, 2006, 2015)
The only school in Saitama Prefecture with a win
The 'Lucky☆Star' school (their quiz win under a Lucky Star-themed team name was big news at the time)

The part I find most impressive about this is…

'wow, they actually had the budget to buy all these materials'…

that's the part.
120AnonymousSep 27, 2026 12:21
Re: #111
Yeah, they seem to be using wood and all kinds of other materials.
There's probably a safety expert overseeing it too, so they likely spent a fair amount.
Maybe they're even angling for this kind of news coverage as publicity.
127AnonymousSep 27, 2026 12:23
Are they going to go coed?
139AnonymousSep 27, 2026 12:26
Re: #127
Saitama Prefecture's board of education had a policy to make it coed, but
alumni and current students ran an opposition campaign and single-sex status was kept.
Same goes for Urawa Daiichi Girls' High School and others.
142AnonymousSep 27, 2026 12:27
Kaminarimon Gate next, then. (the famous lantern gate at Sensoji Temple in Asakusa)
145AnonymousSep 27, 2026 12:29
Re: #142
Knowing them, 'sorry, the giant lantern's in the way, you can't walk through' lol

Background and Key Points of the Debate

The Yomeimon Gate is a National Treasure structure at Nikko Toshogu Shrine, famous for its intricate carvings and vividly colored decoration. Saitama Prefectural Urawa High School is known as a top boys’ prep school, and within 5ch it’s already recognized as having a tradition of building elaborate gates for its cultural festival every year — the thread itself notes “there’s a tradition of spending a whole year building the gate.” Debate mainly split over “how much of this is really handmade,” with some posts speculating about 3D printers or AI design assistance, alongside others praising the clear manual labor behind the assembly and carving. Opinions were also divided on whether it’s appropriate for a college-prep school to pour this much effort into something other than exam study, with some framing it as a proud tradition and others calling it “putting the cart before the horse.” One point readers could easily get wrong: this is an official annual school event, not a one-off special project this year, and no official figures on material costs or safety measures were ever presented in the thread — those remain pure speculation.
