Due to the System Maintenance, SMOKA service will be suspended on January 21, 2026 from 9:00 to 17:00 (JST). Because processing large data requests such as HSC may take about half a day, SMOKA data request will be unavailable from 17:00 on January 20, 2026 (JST). We apologize for the inconvenience (January 13, 2026).
