The Sign Still Says River Museum. It Just Added *'Was.'*

A closed Tokyo museum updated its sign in the laziest, most grammatically correct way possible.

What's going on

In Tokyo’s Meguro ward, a former municipal facility called the “Meguro Ward River Museum” — a small public space dedicated to the history of the local Meguro River — closed down and was repurposed as a coworking space called “Funai River Tatemono” in May 2023. The original sign, a large vertical installation with dark embossed characters reading “Tokyo Metropolitan Meguro Ward River Museum,” was left on the building. Removing or replacing it apparently wasn’t in the budget.

So someone added two characters to the bottom instead, in noticeably white text clearly distinct from the rest: “だった。” — meaning “was.” Period.

Here’s why that lands the way it does. When a Japanese facility moves out of a building, the standard signage approach is to add a prefix like “元” (former) or suffix the address with “跡地” (site of the former ___). These are noun phrases — they label. What this building has instead is a complete sentence. “川の資料館だった。” means “It was the River Museum.” — subject implied, past tense declared, full stop appended. The building isn’t tagging itself as a former facility; it’s narrating its own history, as if composing the opening line of its own memoir. The white text, clearly bolted on after the fact, makes the edit unmistakable to anyone walking by.

Sure, it’s not the River Museum anymore — but is that really how you handle the old sign?
確かにもう川の資料館じゃないけど、そんな看板の保存方法ある?
I happened to be walking by just now and it caught my eye — took a photo too
ちょうどさっき自分も ここ歩いてた時に気になって撮った
was
だった
Not “former site” — just “WAS” lmaooooooo
『跡地』じゃくて『だった』wwwwwwwwwwwwww
Not even “it was (politely).” — just “it was.”
「でした。」じゃなくて「だった。」なのか。

Japanese has two past-tense forms for "was": "でした" (polite/formal) and "だった" (casual/plain). Using the casual form makes the sign feel even more blunt and offhand — like the building couldn't be bothered with formalities about its own history.

Past tense!?
過去形!?
was lol
わず

「わず」is the Japanese hiragana phonetic spelling of the English word "was" — a one-word meta-response to a whole thread about "だった," which means exactly that.

First time I can recall a building explicitly declaring itself in the past tense… lol
今の所、自称で「だった」を明示する建物は無かった記憶…w
Can’t believe this actually got approved lol
これ許可下りたのいいなw
Honestly, I respect the honesty 🤣
正直で良いと思う🤣
It’s giving those trendy celebrity-produced artisan toast shop vibes (a mid-2010s Japanese fad where celebrities backed minimalist premium bread shops with boldly simple signage) lol
なんか、岸本プロデュースの食パン屋みたいな看板になっとるw
Feels like one of those early Vocabulary Heaven wordplay bits (ボキャブラ天国, a 90s Japanese TV comedy show built around puns), you know…
初期ボキャブラの「みなさん、カンバンわ」に近いものがありますね…
Looks like one of those fake Japanese signs you’d find in China. Hao. (Chinese for “nice”)
中国にありそうな偽日本語じみててハオ。
I read this in Shimojo Atom’s voice from Sekai Ururun Taizaiki (世界ウルルン滞在記, a long-running Japanese travel documentary known for its deeply emotional narration)
下條アトムの声で、世界ウルルン滞在記が再生されたわー
The different color is very much TV subtitle energy. My inner narrator is Taguchi Tomoro’o — the voice of Project X (a beloved NHK documentary series about Japan’s great industrial achievements, known for its intensely dramatic delivery)
あえて色が違うところにテレビのテロップ的なものを感じる。脳内ナレーションは田口トモロヲさん(プロジェクトXとかの人)
Mine played back in Hashimoto Satoshi’s voice (a well-known Japanese stage actor with a distinctively resonant, theatrical delivery)
橋本さとしさんの声で脳内再生された。
“It WAS”?? So what IS it now?? 🤣
だったって じゃいまなんだよ?🤣
It’s currently being used as a coworking space, apparently (´・ω・`)
現在は、コワーキングスペースとして活用されているみたいです(´・ω・`)
This is way too much like how parody impersonation accounts get away with things on social media
SNSのなりすましネタ垢みたいなやり過ごし方過ぎる
That’s too much of a life hack
裏ワザがすぎる
I want this energy adopted worldwide
世界中のみんながこういうノリでやっていってほしい
Couldn’t afford to take it down, huh…
撤去費用出せなかったのか…
Probably cheaper to add than to remove? Smart.
撤去より足す方が安かったのかな?上手い。
Love the style of dodging the removal cost like this
これで撤去費用浮かすスタイル好き
Sure, cutting removal costs could be part of it — but I also thought: in a neighborhood where people still navigate by maps listing the old facility name, keeping the sign might actually be clearer than putting up a new one… (though I do wish they’d added what the building is now)
撤去費用削減もあるかもしれないけれど、「旧施設名が載った地図」を頼りに近隣施設に訪れる人が多い地区だと、新しく建物に名前つけるより分かりやすいのかもしれないな…と思いました(が、今何の施設なのかも併記して欲しい気持ち)。
Found a similar one — this one’s even rougher 🤔
似たやつなら見つけた 雑すぎる🤔

My take

Budget cuts from the closure probably left no room for a proper sign swap. But what makes it funnier than just a stale old sign is the grammar. "Former River Museum" is a label. "It was the River Museum." is a statement — delivered bluntly, in casual tense, with a full stop. The building finished its own sentence and walked away.
