The story

A Nikkei report has revealed that visitor numbers to the free clip-art site “Irasutoya” fell 20% year-on-year in September, according to estimates from a data analytics firm. Since its launch in 2012, the site has been widely used — including for pandemic-era awareness posters — but the spread of image generation using generative AI is believed to be behind the decline. In the 5ch thread, fans who conduct “habitat surveys” (hunting for real-world sightings of Irasutoya art around town) were highlighted, alongside clashing opinions — some expressing discomfort with AI-generated images, others arguing the site has already served its purpose.

The free illustration site “Irasutoya” is being squeezed by generative AI. According to estimates from a data analytics firm, the number of site users in September fell 20% year-on-year. Even so, there are still fans collecting real-world examples of its use around town, and collaborations with popular IPs that make use of its distinctive art style. Irasutoya saw a surge in use during the COVID-19 pandemic — can it survive in the age of AI?

Irasutoya is a free material site that illustrator Takashi Mifune started on their own in January 2012…

You can tell they'd already lost motivation the moment they stopped updating it.

Spotted one in London

Re: #3
At a certain academic conference, an American and a Czech researcher once told me,
"There's something these illustrations in Japanese-made data all seem to have in common…"
and I instantly thought, "That's Irasutoya."

But AI art is creepy.
5AnonymousNov 2, 2026 01:43
Irasutoya's art is creepy too, so no issue there.
6AnonymousNov 2, 2026 01:52
They've already made plenty of money off it, so who cares lol
7AnonymousNov 2, 2026 03:24
That's something you grow out of after elementary school, right?
8AnonymousNov 2, 2026 05:10
"Irasuto" lmao
All in hiragana lmao
9AnonymousNov 2, 2026 06:39
These days, using Irasutoya actually gives the impression you're putting in effort instead of just leaning on AI.
10AnonymousNov 2, 2026 07:02
Yeah, you don't see it on TV shows anymore even though they used to work it to death lol
11AnonymousNov 2, 2026 07:27
Isn't one of the reasons that YouTube demonetized Shorts that used 2channel recap content and Irasutoya images?
12AnonymousNov 2, 2026 07:46
Stock images of hackers
usually show someone in a hoodie hiding their face
but the original source is this guy, right?

I think that traces back as far as V for Vendetta's Guy Fawkes mask.
14AnonymousNov 2, 2026 08:29
Classic ν(nu)-soku move — hype something up, then once everyone's bored, drop it all at once.
15AnonymousNov 2, 2026 09:05
AI can crank out Irasutoya-style art exactly to spec, after all.
16AnonymousNov 2, 2026 09:39
While you're at it, do the illustrations for the back of New Year's cards too.
18AnonymousNov 2, 2026 10:12
AI art comes with a bunch of hassle after you use it, so Irasutoya is still fine for now.
19AnonymousNov 2, 2026 10:19
I'm sicker of Irasutoya than I am of AI images.
21AnonymousNov 2, 2026 10:51
"Irasutoya" and "elastomer" sound alike. (just a sound-alike joke)
22AnonymousNov 2, 2026 11:01
Still, there's a flavor only Irasutoya can deliver.
Guess it just depends on the use case.
23AnonymousNov 2, 2026 11:40
I do think Irasutoya is the safest choice overall.
24AnonymousNov 2, 2026 12:52
When you care about tone-and-manner consistency across different illustrations, Irasutoya is the only choice.
25AnonymousNov 2, 2026 13:06
Had AI draw a caricature icon from a photo, and it came out looking exactly like Irasutoya's style — cracked up.
It'll draw anything with no copyright worries, so maybe we don't even need Irasutoya anymore.
26AnonymousNov 2, 2026 13:08
It was just a flash in the pan of the pre-AI era.
27AnonymousNov 2, 2026 13:19
Irasutoya's creator genuinely has skill as an original illustrator.
AI is a substitute, but it doesn't replace Irasutoya's artistic identity.
28AnonymousNov 2, 2026 16:35
Make it Irasutoya-style.
29AnonymousNov 2, 2026 16:40
It used to be the undisputed king of free illustration assets, but AI completely put it out of a job — well, that's unavoidable.
Still, both Irasutoya and AI art have such distinctive looks that you can spot them at a glance — that much they have in common.
30AnonymousNov 2, 2026 16:51
AI-made posters always feel a bit off somehow, but seeing an Irasutoya illustration gives me that cozy feeling of visiting my grandma in the countryside after a long time.
31AnonymousNov 2, 2026 17:57
Re: #1
What "survey" lol, you're just picking your nose and clicking around lol
32AnonymousNov 2, 2026 18:03
Re: #31
It's a field survey.
I know of one spot myself — a big hospital that's adopted it (there are original illustrations on the wall for things like blood-draw directions).
33AnonymousNov 2, 2026 18:51
It's easy to use for government-related stuff.
There's usually a male and female version of each figure, so it's less likely to get criticized over gender issues.
34AnonymousNov 2, 2026 18:54
The thread title looked like "Irazutoya" (as in "don't even need it"?) to me.
35AnonymousNov 2, 2026 19:20
AI just spits it out, no effort needed. Though with zero quality-checking, well, you can imagine…
36AnonymousNov 2, 2026 20:17
I had the site open for months while putting together a manual last year, so my share of visits dropped this year (´・ω・`)

Background and Key Points of This Topic

Irasutoya is a free material site that illustrator Takashi Mifune started individually in January 2012, and usage surged during the COVID-19 pandemic amid demand for posters urging mask-wearing and disinfection. What sparked discussion this time is that, according to estimates from a data analytics firm, visitor numbers in September fell 20% year-on-year, with the spread of image generation using generative AI believed to be behind it. The thread was split between voices saying “AI art still feels creepy and is a hassle” and those saying “AI is a perfectly good substitute,” with several people noting that for uses where safe, inoffensive imagery is required — like government or hospital signage — it’s still in use today. A drop in visitors doesn’t mean the site is finished, and the fact that its position as copyright-free material you can use with peace of mind remains strong for certain uses is something the raw numbers in the article alone don’t fully convey.
