Riken Optical Gokoku No.1

The Gokoku No.1 is an early Japanese folding camera produced by Riken Optical. It is a pre-war small-format folder, representative of the type of consumer cameras Riken made before its later Ricoh-branded output.

Auction data for the Gokoku No.1 is extremely thin: a single UK saleroom hammer result in 2023 stands at £1,400, which is the only reference point for what one currently sells for. With just one wholesale auction sale on record, that figure should be treated as indicative rather than a settled market value in 2026, and the true worth today depends heavily on condition, completeness and bidder interest on the day.
