1SEC Inc.  (Headquarters: Meguro-ku, Tokyo, CEO: Hirokuni Miyaji)  which bases its US operations in Los Angeles and Japan operations in Tokyo and carries out XR software development and blockchain content development and production, announces its partnership with B STONE Co., Ltd. (Headquarters: Shibuya, Tokyo; Representative Director & CEO: Naoko Kuroishi; hereinafter referred to as “B STONE”), which operates the apparel brand Ameri VINTAGE in 1Block Land, the virtual land-style platform based on blockchain technology provided by 1SEC, to sell haute couture through NFTs (non-fungible tokens), which is the first endeavor of its kind to come out of Japan. 

The haute couture created in collaboration with the apparel brand Ameri VINTAGE referenced in this announcement will be made available in 1Block LAND, the virtual land-style platform based on blockchain technology that is provided by 1SEC using the 3DCG production know-how accumulated through planning and developing Japan’s first virtual sneakers and virtual human. This is the first effort to go beyond the boundary between the real and virtual worlds to combine the potential of digital fashion with technology for new forms of expression.

In addition, a portion of the haute couture being announced is scheduled to be made available for purchase through an auction in late October 2021 (tentative) inside 1Block, the NFT marketplace developed by 1SEC, as NFTs.

Design Concept


The land that nature nurtures and the technology that humans create all come together and transcend into art. This nature and technology, along with a story, harmonize and live forever as a work of art.

By creating new experienced value through technology, with a focus on 3DCG and blockchain technology, without stopping the economic and cultural flow in the field of entertainment, 1SEC will continue to support the economic acceleration of brands and creators in order to contribute to the development of the industry.

1Block LAND

A virtual land-style platform based on blockchain technology. It makes it possible to casually enjoy new experiences based on blockchain technology in a virtual space using a web browser on your computer or smartphone. The focus for the initial phase is the shopping experience, as it is possible to make purchases in the tenant shops set up in 1Block LAND using the cryptocurrency Ethereum and credit cards. It offers a new way of shopping through experiences inside the tenant shops that precisely reflect each exhibiting brand’s worldview.
