## About Hajime Sorayama

Hajime Sorayama (born 1947, Ehime, Japan) is a Japanese illustrator and visual artist internationally recognized for his hyper-detailed portrayals of feminine robots and futuristic imagery. He coined the term "superrealism" to describe his pursuit of the highest possible technical fidelity to his subjects, working primarily in acrylic and airbrush on illustration board. A graduate of Chuo Bijutsu Gakuen in Tokyo (BFA, 1969), Sorayama rose to prominence through his Sexy Robots series beginning in the late 1970s — chrome-toned gynoid figures that blend pin-up aesthetics with science-fiction mechanics. His design for the original Sony AIBO robotic dog entered the permanent collections of the Museum of Modern Art in New York and the Smithsonian Institution. Represented by NANZUKA in Tokyo, Sorayama has exhibited solo at Almine Rech, Jeffrey Deitch, the Shenzhen Museum of Contemporary Art, and the Museum of Sex Miami, among many others. His work bridges fine art, industrial design, and pop culture through collaborations with brands such as Nike, Marvel Comics, Lucasfilm, and Disney.

## Common works and media

Sorayama's most commonly encountered works in auction and appraisal contexts include original acrylic-and-airbrush paintings on illustration board (typically depicting his signature chrome gynoid figures), limited-edition bronze and fiberglass sculptures, screen prints and giclée editions from the Sexy Robots series, dinosaur-themed paintings and sculptures from the Dinosauria series, and mixed-media works from the Space Traveler series. Posters and exhibition prints from his gallery shows with NANZUKA and other venues also circulate in the secondary market.

## Market and appraisal context

Hajime Sorayama has a deep and actively traded secondary-market footprint, with 328 auction lots recorded in Appraisily's auction-record index dating back to August 2003 and continuing through May 2026. Of those, 231 lots carried a realized price. The price distribution is extremely wide: the low end begins at $12 for unsigned or low-tier color prints, the median sits at $400, and the 75th percentile reaches $1,260, while the recorded maximum is $5,750,000 — reflecting the enormous gap between mass-market prints and original, large-scale paintings. Liquidity is strong, with 53 lots appearing in the most recent 12-month window and 83 in the prior 12-month window, indicating sustained but slightly contracting volume. Works cross multiple auction categories including contemporary art, prints and multiples, sculpture, illustration, and collectible design. The auction-house roster is broad and international, spanning Christie's and Heritage Auctions at the top tier alongside regional specialists such as Joshua Kodner (Florida), Louiza Auktion & Associés (France), Ravenel (Taiwan), Henry Butcher Art Auctioneers (Malaysia), 33 Auction (Singapore), Yuan Art (Taiwan), Crescent City Auction Gallery (New Orleans), and Tate Ward Auctions (London). This geographic spread — across North America, Europe, and East/Southeast Asia — reflects Sorayama's global collector base.

### Appraisal notes

An Appraisily appraisal for a Sorayama work would draw on this auction-record dataset to establish comparable-lot benchmarks. Because the price distribution spans $12 to $5,750,000, accurate valuation requires matching the subject work by medium (original acrylic-and-airbrush painting on illustration board, bronze or fiberglass sculpture, screen print or giclée, or collectible edition), edition size and number, dimensions, subject series (Sexy Robot, Dinosauria, Space Traveler), signature presence and placement, condition (airbrush surfaces on illustration board are particularly vulnerable to scratching, fading, and foxing), and documented provenance through recognized galleries such as NANZUKA or Almine Rech. The appraiser would also verify whether the item is an original fine-art work or a licensed collaboration product — Sorayama's partnerships with Nike, Disney, Samsung, and Medicom Toy (Be@rbrick) produce merchandise that trades at fundamentally different price points. Photographs of the work, its signature, edition markings, frame or mount condition, and any gallery or exhibition labels on the reverse are essential supporting documentation.

### Collector notes

- Sorayama's auction market is liquid and international, which benefits both buyers and sellers. For buyers: the wide price range means entry-level signed prints can be acquired for under $500, while significant original paintings require a five- or six-figure budget. Always confirm medium and edition status before purchasing — a 'signed print' may be a mass-produced poster rather than a numbered limited edition. For sellers: works from the Sexy Robot series, original paintings, and large-scale sculptures have the strongest demand. Provenance documentation (gallery invoices, exhibition history, certificates of authenticity) materially improves sale outcomes. Be aware that auction volume has slightly contracted (from 83 to 53 lots comparing the prior 12-month to the most recent 12-month window), which may reflect market consolidation toward higher-quality material rather than declining interest. The presence of top-tier houses like Christie's and Heritage alongside regional specialists means works can be consigned at multiple market levels depending on estimated value.

### Market caveats

- The maximum recorded price of $5,750,000 is an extreme outlier; the vast majority of Sorayama lots trade between $50 and $3,000. Appraisals should not anchor to the top-end figure without a comparable-lot basis.
- Price data spans multiple currencies (USD, EUR, TWD, MYR, SGD). Currency conversion was not applied in the source pack; cross-currency comparisons should account for exchange rates at the time of sale.
- Several recent lots from Joshua Kodner and Louiza Auktion have null (unrealized) prices, indicating either unsold lots or results not yet reported. The priced-lot count (231 of 328) excludes these.
- The $12 low-end price likely represents an unsigned or mass-produced print; it should not be treated as a floor for signed or original works.
- Collectible merchandise lots (Be@rbrick figures, skateboard decks, exhibition figurines) appear alongside fine-art lots in the record set. These are distinct market segments with different value drivers.
- The auction-record data is derived from public auction feeds and may not capture private sales, primary-market gallery pricing, or results from houses not indexed in the feed.
