General Comment
The stamp rally is a straightforward service that provides the added benefit of making the visitor experience even more enjoyable.
In addition to the fun of collecting stamps at the stamp stands in participating pavilions, those unable to visit the physical site can also collect stamps by visiting the pavilions on the virtual site. This is a commendable feature, as it allows more people to enjoy the Expo literally “anytime, anywhere”.

General Comment
I have gained a good understanding of the Digital Stamp Rally officially provided by Japan Association for the 2025 World Exposition. While I wondered whether some visitors might not be familiar with the mechanisms and nature of NFTs, I felt there was no doubt that visitors would enjoy the service as a memorable part of their visit to the Expo. The report outlines the anticipated risks of the website and the countermeasures against those risks as a service supporting the Digital Stamp Rally organised by the Association. I found that these risks and countermeasures were carefully considered to ensure users can enjoy the service with peace of mind, within the scope outlined in the report.

General Comment
The stamp rally is an effective service that encourages visitors to explore the venue independently, and the content of the service provided was fully understandable. Additionally, I found that offering NFTs as an incentive is an innovative initiative. However, considering the general level of user literacy, I believe more effort should be made to explain the appeal of NFTs in a clearer and more accessible manner. Furthermore, given the way the data is handled, privacy risks are considered to be minimal.
