The law of the search

Metal Detecting and Treasure Laws in Japan

Mixed
Metal detecting. No outright ban, but found property must be handed to police
What happens to finds. Buried cultural property belongs to the state

Worth knowing

Private archaeological detecting is discouraged.

This is a plain-language starting point, not legal advice. The rules change and vary by county, city, park, and parcel, and federal land carries its own restrictions. Always confirm with the specific land manager or agency before you search, and record and report finds where the law requires it.
