It has come to light that Sanseido Bookstore Ikebukuro Main Store, a large bookstore directly connected to Ikebukuro Station, will close at the end of December 2026. Housed inside the Seibu Ikebukuro main store and cherished by countless customers for years, the closure of such a fixture set off a wave of shock and sorrow on 5channel threads, with comments like “This is so shocking I’m at a loss for words.” The discussion expanded to cover what might replace the store, comparisons with other major bookstores like Junkudo and Kinokuniya, back-of-the-envelope debates over whether shoplifting losses are squeezing the store’s finances, and references to the wave of bookstore closures in Jimbocho and Shimokitazawa.

filled in by people who never even shopped there
Maybe it'll become a Yodobashi book corner or something
Huh, didn't think of that
Or maybe they'll just expand the department store food hall (depachika) instead
Quit only going to the doujinshi shops 😡
Used to want to root for them, but there've been more and more obnoxious bookstore clerks lately, so honestly, let it go under
I want Shosen to keep hanging in there with its niche/otaku selection
It's part of the Animate Group now.
With prices jacked up this much, no wonder no one can afford to buy
Even trashy weekly magazines run around 500 yen now
Kills any urge to buy
Prices are shooting up on everything these days.
I think Japan was at its richest back in the early 1990s, when the second baby-boomer generation (dankai junior) was in college.
Just a matter of time now
Family Book was open 24 hours, with games, CDs, DVDs, books, stationery, and sundries on the first floor and a CD/DVD/manga rental floor upstairs — it was like a dream store.
GEO bought it out ages ago and turned it into just another generic GEO.
It used to have all kinds of weird random goods, though.
and heading over to Junkudo.
Yeah, that was the rainy-day route
A hardcover volume runs close to 1000 yen
Can't casually pick one up anymore
You mean a paperback (bunko), not a hardcover?
If one book gets shoplifted, you'd need to sell 30-50 copies of that same book just to break even — that's just not viable as a business
They should be selling everything out of locked glass cases at this point
Pretty naive take
That's basically how the margins work for any mass-produced good, not just books
— bet they'll air an interview exactly like that
There's always some closing-day superfan who shows up everywhere
Like, dude, you had nothing to do with this place
It really was confusing to navigate spatially, huh
Yeah, the sales floor was kind of split up, so if you weren't used to it you'd end up wandering around lost
Junkudo had each floor sorted by genre, which made it a lot easier to shop
not sure what they call that Seibu Line ticket gate,
but going home in through there
was my classic long-way-home route — it's a shame to lose that
Same here — that was my route back when I lived in Nerima
1. Hakodate Tsutaya Bookstore (Hokkaido), 8,265㎡
2. Tsutaya Bookstore Foreo Shobu (Saitama), 7,590㎡
3. Maruzen & Junkudo Umeda Store (Osaka), 6,813㎡
4. Tsutaya Bookstore Kumamoto Sannenzaka (Kumamoto), 6,662㎡
5. Junkudo Bookstore Ikebukuro Main Store (Tokyo), 6,621㎡
6. Coach and Four Tsukuba Store (Ibaraki), 6,600㎡
7. Maruzen Marunouchi Main Store (Tokyo), 5,786㎡
8. Kashiwanoha Tsutaya Bookstore (Chiba), 5,600㎡
9. Tsutaya Bookstore Miyazaki Takachiho-dori (Miyagi), 5,574㎡
10. Maruzen & Junkudo Sapporo Store (Hokkaido), 5,294㎡
Hokkaido's impressive
Way out in front, no contest
In Ikebukuro I used to go a lot back in the Libro days
The Sanseido in Shimokitazawa also closed this past January when the building got torn down for redevelopment
Bookstores in Jimbocho have really thinned out too, it's mostly restaurants now
Fewer bookstores, more izakayas
I didn't even know Sanseido had opened a branch in Shimokitazawa.
Since when has your clock stopped ticking?
That became a Bic Camera West Exit store ages ago
If you go inside, the building layout is the same,
so you can still catch traces of the old Horindo
Background and Key Points of Discussion
Sanseido Bookstore Ikebukuro Main Store was a large-format shop that had operated for years in the prime location directly connected to Ikebukuro Station, inside the Seibu Ikebukuro main store, and was distinctive for having its sales floor split between the book hall building and the department store’s annex. Opinions in the thread diverged over where to place the blame for the closure. Some pointed to structural factors like price hikes and the spread of e-books, while others got into a back-and-forth of specific numbers—wholesale rates, gross margins—debating whether the cost of shoplifting losses was squeezing the store’s finances, with no clear consensus reached. It was also notable that this closure was discussed against the backdrop of a string of shutdowns among long-established Tokyo bookstores, such as Shosen Book Mart in Jimbocho and the Sanseido Bookstore branch in Shimokitazawa. Note that what’s closing here is specifically the Ikebukuro Main Store location — the Sanseido Bookstore chain itself is not disappearing. Since the article’s text doesn’t spell this distinction out clearly, readers should be careful not to conflate the two.
