Akihabara Radio Kaikan Hobby Floors for Model Builders

4F — AmiAmi

The current official Radio Kaikan floor guide lists AmiAmi on 4F. Use this floor for a broad hobby comparison: plastic models, tools/materials and used hobby goods sit alongside figures and character goods.

6F — Yellow Submarine Akihabara Main Store ★ Mint

The building's current floor guide lists Yellow Submarine on 6F. Its own store information covers new and used character plastic models, Mini 4WD, tools/materials and related hobby products.

8F — Volks Hobby Square Akihabara

The current Radio Kaikan guide lists Volks Hobby Square on 8F. Volks describes the floor as a large specialist hobby space covering scale models, railway models and tools/materials in addition to other hobby categories.

Do not visit every floor by default

Keep the building as one stop

If the first floor answers your question, moving upward is optional. Use our wider Akihabara guide when you also want Surugaya or another building.

Use one building as a controlled comparison

Before entering, write one primary target and one secondary need. For example: “RG kit first, nippers second.” Start on the floor most likely to answer the primary need, record the exact product and price, then move only if another floor adds a different category or a useful comparison. This keeps Radio Kaikan from becoming a repetitive floor-by-floor browse and makes it easier to stop once the purchase question is answered.

Exit rule

If one floor gives you the exact kit or tool you planned to buy at acceptable terms, stop comparing unless another floor has a specific role in your shortlist. The goal is to use Radio Kaikan's vertical density efficiently, not to turn the building into a mandatory eight-floor browse.
