NID Inc. (Chuo-ku, Tokyo; President: Shuntaro Komori) and World Park Inc. (Chiba City; President: Yuzuru Nishida) will launch the 'SUNSET Index' at Inage Seaside Park starting Saturday, May 2nd. This initiative is part of an update to the 'SUNSET BEACH MAP' digital map, accessible to everyone via smartphone.
By knowing the sunset score in advance through the SUNSET Index, visitors can better plan their activities, such as walks or photography sessions. Additionally, a new coupon service linked to the index will begin. Higher scores will trigger more valuable coupons, encouraging visitors to enjoy park facilities more easily while watching the sunset. A puzzle-solving event using the map and index will also be held during the Golden Week holidays.
### About the SUNSET Index
The SUNSET Index is a metric that scores the beauty of the sunset from 0 to 100%. This value is predicted and calculated by an AI model independently developed by NID. It was created through repeated verification using various data, including weather information and actual sunset conditions, with cooperation from World Park. The index provides forecasts for up to four days, including the current day, enabling visitors to choose the best days to visit based on their goals.
### Coupon Functionality
In conjunction with this release, a function to deliver coupons around sunset time will be added. Facilities offering coupons can be checked on the map, and the content of the coupons will change based on the SUNSET Index score. Days with higher scores will feature better deals, making the sunset experience even more special.
### Commemorative Puzzle Event
To celebrate the release, the 'SUNSET BEACH MAP Mystery Walk' will be held during the Golden Week period (May 2–6, 2026). Participants will explore the park to find clues based on a story themed around the sunset and the wooden deck extending into the sea. This event aims to help visitors discover new charms of the park's scenery and facilities.
### Development Background and Future
Inage Seaside Park has long been loved for its beautiful sunsets. World Park, the operator, has enhanced this appeal by renovating the area, including the signature wooden deck. NID, sympathizing with World Park's innovative spirit, provides digital technology support to further evolve the park experience. Following the digital map launch in December 2025, this update marks a deeper collaboration to improve visitor convenience and promote exploration within the park.
