Julien's Auctions launches the first-ever sale of Sompote Sands' personal Ultraman collection to mark the franchise's 60th anniversary

Executive summary: Julien's Auctions issued a press release (in French) announcing the "Kaiju King: The Sompote Sands Legacy Collection" auction, the first public sale of the personal Ultraman archive of Thai filmmaker Sompote Sands, scheduled for the franchise's 60th anniversary. The auction establishes a new high‑profile provenance for vintage Ultraman memorabilia, potentially setting price benchmarks for Japanese tokusatsu collectibles and highlighting the growing institutional interest in Asian pop‑culture heritage assets.

Who is involved: Julien's Auctions (auction house), the estate of Sompote Sands (Thai sci‑fi filmmaker), Tsuburaya Productions (Ultraman rights holder), and collectors of vintage Japanese character goods.

Likely next (inference): Julien's will publish a detailed catalogue and auction calendar; the sale will likely take place in late 2026, with pre‑sale exhibitions in major markets (Los Angeles, Hong Kong, Tokyo).

Julien's Auctions has announced a dedicated auction of the late Thai filmmaker Sompote Sands' private archive of Ultraman memorabilia, including rare promotional flying miniatures, design statues, masks, production suits, figurines and 3‑D artwork. The sale is timed to coincide with the 60th anniversary of the pioneering Japanese tokusatsu franchise. The collection represents a unique provenance directly from a visionary sci‑fi creator who helped introduce Ultraman to Southeast Asian audiences. This auction creates a new benchmark for vintage Japanese pop‑culture collectibles in the international market.
