Kenso Soai Wins Nobel Prize in Chemistry — Even NHK’s Pundits Call It ‘Unexpected,’ While His Handwritten Notes Steal the Show

The story

Tokyo University of Science Professor Emeritus Kenso Soai has been awarded the 2026 Nobel Prize in Chemistry jointly with Paris-Saclay University Professor Emeritus Henri Kagan. The prize cites “the discovery of nonlinear effects and autocatalysis in asymmetric organic synthesis.” This marks the third consecutive year a Japanese national has won a Nobel Prize, and the 10th Japanese Chemistry laureate, following last year’s Susumu Kitagawa. NHK’s “News 7” led with the story, but even pundits said they “hadn’t expected this for the Chemistry Prize,” since Soai’s name was missing from the pre-announcement prediction lists — sparking surprise across 5ch. Meanwhile, the cute handwriting on what looked like a hastily scrawled note at the announcement became its own hot topic, with the thread spiraling into side discussions on the feasibility of fusion power and the annual running joke about Haruki Murakami’s Literature Prize snub.

Tokyo University of Science Professor Emeritus Kenso Soai has been named a winner of this year’s Nobel Prize in Chemistry. The Royal Swedish Academy of Sciences made the announcement on the 7th. The prize was awarded “for the discovery of nonlinear effects and autocatalysis in asymmetric organic synthesis,” shared with Paris-Saclay University Professor Emeritus Henri Kagan. This is Japan’s third straight year producing a Nobel laureate, the 31st Japanese individual recipient overall, and the 10th in Chemistry, following last year’s Susumu Kitagawa.

The good news broke just after 6:50 p.m. Japan time on the 7th. NHK’s “NHK News 7” ran it as the top story.

23 hours until Haruki gets passed over again — the countdown begins

Was watching the Miraikan (National Museum of Emerging Science) livestream on Niconico, but apparently he was a total dark horse

Nobel Prize in Literature
I wonder if the Harukists are gathering again this year, hoping Haruki finally wins ("Harukist" = devoted fan of author Haruki Murakami)
19AnonymousOct 7, 2026 20:35
Re: #12
Are there actually any Harukists who genuinely believe Haruki's going to win?
20AnonymousOct 7, 2026 20:35
Seriously, NHK's predictions never come true.
They had several names predicted for yesterday's Physics Prize so I was hopeful, but…

He wasn't even on Nikkei's rankings. And they were so proud of having built a "prediction machine," too.
21AnonymousOct 7, 2026 20:35
Winning a Nobel Prize is pointless if it can't be commercialized (dead serious)
23AnonymousOct 7, 2026 20:37
Re: #21
Is there even any cutting-edge science left that can actually be made practical anymore?

Fusion power sure won't be commercialized within your lifetime either.
News like this just feels hollow now…

Re: #23
Fusion's had breakthrough after breakthrough, it's gotten to a point where it seems fairly achievable
but in the end it's a battle of capital, and that's where it loses
Plus with the Nobel Prize too, there are people doing similar research all over the world — the winner's just whoever got there first
If you can't actually roll it out into society and build the right environment for it, it means nothing
34AnonymousOct 7, 2026 20:47
Re: #31
To make it practical you absolutely need
input < output
It's made plenty of headlines
but if you actually scrutinize it, no real breakthrough has happened
37AnonymousOct 7, 2026 20:50
Re: #31
With fusion, it's like room-temperature superconductivity — people have been saying it's coming since the Showa era (pre-1989), and it's just not happening
27AnonymousOct 7, 2026 20:40
"We didn't expect this for the Chemistry Prize" — wait, did people think it'd go to Biology instead?
29AnonymousOct 7, 2026 20:41
Apparently there are only 30 people in the entire country with this surname
30AnonymousOct 7, 2026 20:42
First real surprise since Koichi Tanaka, huh.
Back then it was genuinely a "who?" moment — not just among the media outlets, but even at the company he worked for, people were saying "we don't even know if this is real" and had to go verify the facts.
I think the press conference ended up being held the next day, if I remember right.

Re: #1
> "the discovery of nonlinear effects and autocatalysis in asymmetric organic synthesis"

At times like this, asking an AI to explain it in plain terms really helps
35AnonymousOct 7, 2026 20:48
I wonder if the anchors on tonight's news shows will actually understand what the commentators are explaining
36AnonymousOct 7, 2026 20:48
Out of all the Nobel Prizes,

the Economics one is the only category no Japanese person has ever won
38AnonymousOct 7, 2026 20:50
The biggest obstacle to making fusion power practical
This is probably a wall that can't be cleared
(This is from AI, but it's what I looked up before)

– The biggest challenge in making fusion power practical is stably sustaining ultra-high-temperature plasma above 100 million degrees for long periods (steady-state operation), and developing reactor walls and materials durable enough to withstand it.

– Enormous construction costs:
Even at the experimental-reactor stage, projects like ITER (the International Thermonuclear Experimental Reactor) require trillions of yen in funding, making the economics of commercialization hard to see.

Laughed at how messy the handwriting was
Guess there wasn't even time to print it out
41AnonymousOct 7, 2026 20:55
It's written in such heavy katakana-English that it's weirdly reassuring (katakana-English = Japanese phonetic spelling of English words)

Re: #42
This handwriting's cute enough they could sell it as a font
70AnonymousOct 7, 2026 21:32
Re: #42
My parent's a science elite too, and their handwriting is genuinely awful
71AnonymousOct 7, 2026 21:33
Re: #42
I was so distracted by the handwriting that not a word of the explanation sank in
44AnonymousOct 7, 2026 20:56
He'd always been floated as a candidate, but honestly my first reaction is just "wow, he actually won"
45AnonymousOct 7, 2026 20:56
So it's not one of those broad-but-shallow-coverage kind of achievements after all
47AnonymousOct 7, 2026 20:58
Well, the Nobel Prize usually goes to research from ages ago,
so a lot of the time it's already been put into practical use

like the blue LED
49AnonymousOct 7, 2026 20:59
Old media can't help but let their bitterness show through lol
50AnonymousOct 7, 2026 21:02
I think it's pretty ridiculous how everyone fawns over a prize named after some guy who invented dynamite, picked by a bunch of nobodies from a foreign country.
People who gush over some foreign tire company's restaurant ratings, done by outsiders with no business judging food, are the same type. (Reference to Alfred Nobel and the Michelin Guide, published by the tire maker Michelin)
61AnonymousOct 7, 2026 21:19
No news outlet has given an easy-to-understand explanation yet
I can't even tell if my own understanding of it is right
65AnonymousOct 7, 2026 21:21
Re: #61
Exactly
It's like explaining benzene-ring theory to someone from the 16th century — they'd never get it
This is that kind of thing

Background and Talking Points

This marks the third consecutive year a Japanese national has won a Nobel Prize, the 31st individual Japanese laureate overall, and the 10th in Chemistry following last year’s Susumu Kitagawa. The thread’s recurring “didn’t see this coming” reactions stem from the annual tradition of outlets like NHK and Nikkei compiling prediction lists based on citation counts and similar metrics — Soai’s name simply wasn’t on them. The slow scheduling of the press conference echoed the same “can we even confirm it’s really him” confusion seen when Koichi Tanaka won. Opinions split between those praising the academic significance of the win (basic research into asymmetric organic synthesis) and a more cynical, practicality-focused camp arguing that “a Nobel Prize means nothing if it doesn’t lead to real-world commercialization” — a debate that branched out into side arguments over whether fusion power will ever become practical. Worth noting: the phrase “awarded jointly with Kagan” doesn’t mean the two collaborated — it refers to them being honored at the same time for separate work in a related field, a point that caused some confusion within the thread itself and is worth clarifying here.
