Japan AI Data Center Feed
Track the best-known public timeline years for AI data center projects in Japan.
This feed is currently powered by the dataset’s strongest shared timeline field: start_year. It gives the index a real, linkable chronological surface now, while more precise milestone feeds can layer in later as announced_year, construction_year, and operational_year coverage improves.
