Proof of Japan, INC. (POJ) produced a collaboration project with Holders of “Azuki” NFT, a globally popular
NFT series, and Hyougu master (Japanese art mounting craftsman) Masahiro Inoue.
Hyougu was introduced from China as a technique for preserving Buddhist scriptures, and later developed into a uniquely Japanese form with decorative features. It is a traditional craft that has been mainly used for hanging scrolls, folding screens, and sliding doors in the alcoves of Japanese-style rooms.
Masahiro Inoue (Inoue), the third generation Hyougu master of Inoue Kogado, while works on traditional
interior decorations, also aims to create a new style of Japanese decoration by searching for the best way to
match modern architectural style, through the theme of “Traditional Elements of Hyougu x ART”.
POJ aims to create special experiential value in both digital and physical spaces, while making full use of AI
and NFT technologies, in collaboration with the young generation who will succeed the future of Japanese
culture and entertainment. In October last year, with the cooperation of Inoue, we have started offering
workshops to create new experiential value by using AI to mount photos and digital arts and transform them into NFTs in collaboration with overseas Web3 platforms.
POJ focuses on the common essence of mounting technology, which adds decorative value to real objects and preserves them, and NFT technology, which adds asset value to digital objects. Through planning a new
initiative to mount PFP (Profile Picture) of the globally famous “Azuki” NFT community, we will provide
experiential value that visualizes the connection between digital and real through mounting and aim to make
“Hyougu” accessible to the next generation around the world.
The material used for the mounting is Japanese paper made by traditional methods, and Azuki NFT holder’s
PFP is mounted with the techniques of Masahiro Inoue, who has been involved in many mounting restorations. The depth and richness of expression of the traditional Japanese mounting technique enhances its appeal.


Masahiro Inoue
Masahiro Inoue has been engaged in the restoration and renewal of Japanese paintings, calligraphies, and
other artworks, as well as mounting of shrines and temples. He has also produced many works that fuse
mounting and contemporary art, as well as Japanese painters and calligraphers. As an approach to
contemporary architectural styles, he has created many new mounting works using the traditional materials and techniques used in mounting. Through Hyougu, he is committed to the transmission and dissemination of traditional techniques.
