ISAS and NASDA conduct their spacelaunch activities at two separate sites. The oldest facility is known as the Kagoshima Space Center and is maintained by ISAS on Kyushu Island. All M-3SII missions are launched from Kagoshima which will also support future M-5 flights. NASDA operates the Tanegashima Space Center on the island of Tanegashimasouth of Kagoshima for all H-class vehicle launches. The H-I launch pad is currently being modified to support the new J-I vehicle. A new facility about 1 km away was constructed for H-II operations. Due to strict fishing industry requirements, all Japanese launches from both Kagoshima and Tanegashima are limited to two 2-month periods each year: January-February and August-September. Consequently, the current maximum flight rate each year is two M-class, two J-class, and two H-class launch vehicles.
