▼About the new "SUNSET Index" feature
The SUNSET Index is a metric that visualizes the beauty of a sunset from 0 to 100%. By being able to check the score in advance, visitors' expectations for "what kind of sunset can be seen today" will grow, providing an opportunity to enjoy their time in the park more, whether through strolls, photography, or cafe visits.
Displays the beauty of the day's sunset numerically, providing forecasts for several days in advance.
This value is predicted and calculated by an AI model uniquely developed by Nidei Co., Ltd.
It was developed through repeated verification using various data, including weather information and actual sunset conditions, collected jointly with World Park. The SUNSET Index supports not only predictions for the current day but also for several days in advance, allowing visitors to check the index for up to 4 days, including the current day, on the map. This enables visitors to choose days when "the sunset is likely to be beautiful" to visit the park, depending on their purpose, such as photography or a stroll.
Inage Kaihin Park has long been popular among many visitors as a place to enjoy beautiful sunset views. As part of its efforts to position "sunsets" as a major attraction of the park, World Park is receiving support from Nidei, utilizing digital technology, with the aim of further developing the park experience centered around sunsets.
This release also simultaneously launches a coupon distribution function linked to the SUNSET Index.
It adds a new feature to distribute coupons before and after sunset at park facilities registered on the map, according to the SUNSET Index score. On days with a high index, more advantageous benefits will be distributed, with content varying by day.
