Did this itinerary last November and it held up well. Sharing because I couldn't find a concise version of this before I went.

Morning — Akihabara: Start at Yodobashi Camera main building (opens 9:30). Floors 4–6 for gaming hardware and accessories. Then Radio Kaikan for retro games and figures. Super Potato if you're into vintage consoles — prices have gone up but the selection is still unmatched.

Afternoon — Nakano Broadway: 15 min on the Chuo line. Smaller and more curated than Akihabara. Mandarake stores across multiple floors — good for older anime merchandise and sealed games. Less tourist pressure.

Evening — back in Akihabara: Yaesu Book Center for gaming art books and strategy guides (some English sections). End at a game center for UFO catchers if that's your thing. Taito Station on Chuo-dori has the best machine selection.

Budget in JPY: I spent roughly ¥40,000 across both spots. Half of that was one very good Saturn game I don't regret.
