Akihabara Deep Cuts: BEEP and the Retro Game Camp Dungeon

Why These Two Are Worth the Detour

Parts 1 and 2 of this series cover the shops most visitors hit first — Super Potato, Mandarake, Trader, Retro Game Camp's main store, and the big chains. The next two are a short walk further out, and neither one is trying to be a one-stop shop. BEEP specializes in the Japanese PCs and arcade boards that most general retro shops don't carry at all, and the Retro Game Camp Dungeon Store is a second, separate space from the chain's main location, worth a special trip if you want stock the main store doesn't have. Neither is essential on a first pass through Akihabara — but if you already know you're hunting for something specific, this is where you go next.

Store-by-Store Notes

• 
  BEEP Akihabara · BEEP秋葉原 — 15-1 Kanda-Neribeicho, Chiyoda-ku (SEEKBASE AKI-OKA MANUFACTURE, Block 3). 12:00 PM–8:00 PM weekdays, 11:00 AM–8:00 PM weekends, closed Wednesdays. Relocated in June 2026 — older maps and blog posts still point to the former address near Chuo-dori. Double-check before you go if you're working from an older guide. Once inside, look past the console games: this is the shop for PC-9801, X68000, and other Japanese home-computer hardware, plus arcade PCBs and cabinets that most Akihabara shops don't stock at all.
• Retro Game Camp — Dungeon Store · レトロげーむキャンプ ダンジョン店 — 3-14-6 Sotokanda, Chiyoda-ku, Ekou Building B1. 11:00 AM–7:30 PM, half an hour earlier than the main store. This isn't the shop covered in Part 1 — it's a second, separate space run by the same company, just past Akibao~ from the main Retro Game Camp store. Think less curated shelf, more cardboard box: this is where the loose Super Famicom cartridges pile up.

One Runs on PCs, the Other on Piles

The contrast between these two is the point. BEEP prices things individually and tags each one — you'll see PC-98 towers next to sealed Neo Geo carts well into six figures, everything catalogued to match. The Dungeon Store is the opposite: cheaper stock, less curation, more digging. If BEEP is where you go to find the rare thing you already knew existed, the Dungeon Store is where you find the thing you didn't know you wanted.

Before You Go

Both of these shops reward knowing exactly what you are after before you walk in. Look your want-list up on Kataban first and write down the product codes (型番). BEEP's tags and the Dungeon Store's boxes are both labelled in Japanese, and the code printed on the spine is the one thing that reads the same in either shop.
