8K Plays a Role in Access to Cultural Treasures
One of the uses of the very high resolution provided by 8K is in the display and inspection of cultural artifacts using digital technology. This has the advantage of protecting what may be very fragile documents or materials, while allowing very detailed review. It can also allow those that are not physically close to the artifact to study it. Japan, as the pioneering nation of 8K, has been leading in this work and we have reported on several projects in that country.
The Digital Gallery of Hōryūji Treasures
At the Tokyo National Museum, there is an exhibition available until January 25, 2026, that is featuring as the ‘Digital Gallery of Hōryūji Treasures’. The Hōryūji Temple is in Ikaruga, Nara, in Japan (30km from Osaka) and was founded by Prince Shōtoku, with building completed in 607. The temple has been described as the oldest existing wooden building in the world. The prince was son of the Emperor and he instituted many reforms in the ways of government after the arrival of Buddhism to Japan and those changes promoted more stability. In time, he became considered as an incarnation of the Buddha.
Inside the temple were housed paintings on sliding doors that told the story of the life of the prince. They were painted in the 11th century, with copies made in the 18th century (those copies are currently on display in the temple). Meanwhile, the original paintings are in the Gallery of Hōryūji Treasures in the Tokyo National Museum. The painting is highly regarded as a very early example of the the Yamato-e style of painting. There is more about the painting on YouTube. The Illustrated Biography of Prince Shōtoku is viewable until July 27th 2025 at the Tokyo National Museum.
8K Makes the Treasures Accessible
In the Digital Gallery of Hōryūji Treasures, visitors are able to use an 8K monitor to study digital reproductions of historic objects from the temple which cannot be put on permanent display. The displays include the paintings of the life of the Prince, but also murals from the Kondō Hall. Other replicas reconstruct what Gigaku masks and costumes may have looked like in their heyday.
The Kondō Hall murals were damaged in a fire in 1949 but in 1935 a number of photographic glass plates were created. These plates were specially prepared for the project and each was up to 24 in. x 18 in. (61 cm x 46 cm) or around A2 paper size. The plates have been scanned at 1,500ppi with digital images receated in five sections of each mural. The images were processed and combined to create images of between 1.7 and 3 gigapixels. Although the content can be accessed online, it is especially impressive when viewed on the two 70″ 8K monitor in the Gallery. The murals will be viewable from July 29th 2025 to January 25 2026
There is an extended description of the Digital Gallery here.
Sharing 8K Content Around the World
In a separate project, NHK of Japan has worked with five universities in Japan and Harvard University in the US to allow the detailed examination of another national treasure from the Hōryūji Temple. The Kuse Kannon sculpture is believed to have been made in the Asuka period (7th Century). 11 other artifacts were also scanned and photographed to create 3D documentary footage. The content was shown on NHK’s 8K broadcast channel in Japan. You can find more details on the scanning and modelling here but to give a sense of the detail, the 3D CG model of the Kuze Kannon consists of approximately 6.65 million polygons and 17 8K-resolution textures!
High definition 3DCG images of the national treasures were shared onto the cloud, and displayed on the monitors and projector screens in the classrooms of the six universities, and when one school operated the 3DCG images using a game controller in their classroom, the 3DCG images of all the universities move in sync. Students noticed details that had previously not been noted in the presentation.
Professor Yukio Lippit of Harvard, who took part in the project, said the 8K result
“was a revolutionary teaching format that will change the future of art history education”.
