開店閉店. com is a Japanese information website that gathers news about store openings and closures across Japan. It helps readers follow changes in their local shopping, dining, leisure, and service landscapes through regularly updated articles organized by region and business category.

Listings cover a wide range of locations, from individual cities and prefectures to broader areas such as Tohoku, Kanto, Kansai, and Kyushu, and include businesses such as restaurants, retailers, hotels, cafés, and fitness clubs. Visitors can browse opening and closing information separately, use the site’s search function, or explore recent posts to find specific locations and types of business. The website also invites readers to submit information, supporting its collection of local updates, and offers email subscriptions for notifications when new posts are published.

Its archive provides access to earlier articles, with posts from October 2010 through June 2024 available through the previous site. In addition to serving everyday readers, the site’s collected information has also been made available for academic use through a dataset hosted on Hugging Face
