刀剣鑑賞 is a mobile application that allows users to appreciate Japanese swords in detail. With its high-resolution digital archive data and unique analysis technology, this app visualizes the characteristics of each sword and provides easy-to-understand points for appreciating them. Users can enjoy the experience of sword appreciation on their smartphones.

The app offers two main features. The first is the "Digital Appreciation" mode, where users can freely explore and admire the swords through touch controls. They can move, zoom in, and flip the swords, and even manipulate the light source to illuminate specific parts of the blade, replicating the experience of viewing a real sword. The second feature is the "Navigation" mode, which provides detailed points for appreciating each sword at the user's own pace. Users can also participate in interactive sections, simulating the experience of attending a sword appreciation event.

In addition to these features, the app includes a detailed information page for each sword, providing an overview and information on where the sword can be viewed in real life. There is also a "Treasure Vault" feature in the full version of the app, which introduces related equipment and additional information about each sword, enhancing the enjoyment of sword appreciation.

刀剣鑑賞 is a free app, but a paid version is available for purchase, offering additional functionality such as the ability to display swords in a virtual tokonoma (a traditional Japanese alcove for displaying art) and access to the backside of the swords for appreciation. Furthermore, a portion of the app's revenue goes towards supporting the owners of the swords featured in the app.

Please note that this app is only available for iOS devices running iOS 11.0 or later.
