The story
On September 30th, central Tokyo recorded precipitation on every single day of September — a first since records began. The streak of consecutive rainy days has also reached 35, likewise setting a new record for the longest such stretch on record. Once October arrives, the autumn rain front is expected to retreat and clear skies should become more common, but all of September brought a steady mix of chilly temperatures and rain. On 5ch, a thread about this record-breaking rainy spell branched off into several hot topics — comparisons with past long rainy spells, claims that it was actually sunny on the 13th along with pushback against that claim, complaints about inadequate flood-control infrastructure, and suggestions for which industries actually profit from the rain.
Today, September 30th, it rained again in central Tokyo, marking the first time on record that precipitation has been recorded on every single day of September. The streak of consecutive rainy days has also reached 35, continuing to set a new record for the longest such streak on record. In the Kanto region, cloud cover will remain heavy through the afternoon and the chill will continue, but once October arrives, clear weather should finally become more common in many areas.

What people said
Is this one longer than that?
That's the year Liu Bei declared himself King of Hanzhong, right?
I don't think it rained that much back then
You were probably just living off shellfish and acorns back then anyway
The guy who got one laugh out of a joke and now won't stop repeating it
You can actually eat "sarumatake" (lit. "underpants mushroom" — a joke fungus name)
Nice try, that's a made-up story ("usomatsu" — slang for an obvious fib)
Yeah, it was sunny
But it probably drizzled for a few minutes at some point in the day
Rain was recorded at Edogawa Rinkai on the 13th
35 straight days of rain…
what is even going on
Floods next year, floods the year after that, and eventually they won't be able to keep up with the infrastructure — it'll end up as an abandoned, uninhabited marshland dotted with ruins
If the autumn rain front disappears, that means cold air is moving in, so it should actually get cooler
Alright, I'll trust you and put my summer clothes away
Well, every year I end up dragging out the futon and blankets around mid-October anyway, so it should be fine — but don't blame me if it's not
In 2023 it topped 30°C on November 3rd
this year's Buzzword of the Year is probably going to be "the Riku-Ryu Pair" (the figure skating duo)
and the Kanji of the Year will be "Gold"
Even with all these disasters,
lately disaster-related words don't get picked anymore since it's just a downer
I think this year's Buzzword of the Year is gonna be "dopa-gaki" (slang, roughly "dopamine junkie kid")
Might be time to redo the whole urban flood-control plan
Most of this could've been stopped with just one retention basin
But no, developers keep building houses on rice paddies for profit, and this is the result
Modern Japan doesn't actually do real urban planning in the first place
We really do need those super-levees
The streak's come this far already — part of me wants to see it run all the way through the rest of the year
Apparently during Kumagaya's record heat, someone was out there sprinkling water on the street to cool off,
and a scary-looking old guy told them
"Cut that out, there's a heat record riding on this"
I'll go mist some water into the weather station box (the white instrument shelter used for official readings)
Maybe just raincoat and umbrella makers?
Food delivery
They're cleaning up every single day
Clothes dryers
Coin laundromats
Rain boots
Raincoats
so I just chucked them into the overgrown vacant lot next door
I wonder what happened to them. You think the rain rotted them away by now?
lol that's savage
It's Lord Masakado's curse~ (the vengeful spirit said to haunt those who disturb his grave)
If you do it again in early summer, it'd be nice if it cooled the summer down too
If it's nothing but rain, people sometimes offer sacrifices praying for clear skies too (rituals to stop the rain and summon the sun)
Moderation in everything matters
Not gonna happen 🤣
Background and Key Points of This Discussion
“A first in recorded history” means this is the first time since Tokyo’s weather observations began in 1876 that precipitation has been recorded on all 30 days of September. Since “precipitation” here includes even a trace amount of rain, it doesn’t mean it poured every single day in a way people could actually feel — even on days like the 13th, when it was mostly sunny, the day still counted as having recorded rainfall. That’s exactly what sparked the disagreement in the thread, with some posters insisting “it was sunny on the 13th” and others countering that rain was recorded at Edogawa Rinkai that day. The streak of 35 consecutive rainy days is being updated at the same time, driven by a stalled autumn rain front. The thread also touched on flood-control infrastructure, with some blaming a shortage of retention basins and poor urban planning, while others pointed out industries — like food delivery and coin laundromats — that actually benefit from the rain. Clear skies are expected to increase once the autumn rain front retreats in October, but that’s no guarantee the long rainy spell is truly over.
