Welcome to Japan Schedule Coodination(JSC)

Japan Schedule Coordination (JSC) is an independent non-profit organization under the Japan Aeronautic Association (JAA) which is a national foundation established for the purpose of promoting the development of aeronautics and astronautics in Japan and enhancing the cooperation with world aerospace communities. JSC is in charge of slot allocation for Narita International Airport (NRT), Tokyo International Airport (Haneda) (HND) and Fukuoka Airport (FUK) and schedule facilitation for Kansai International Airport (KIX) and New Chitose Airport (CTS).

Slot Monitoring

10th Edition of IATA WSG became effective on 1 August 2019 which is downloadable from the bottom of this page. The significant change compared with the previous edition is the inclusion of “Slot Monitoring” which is described in a new Chapter 9. Based on this inclusion, the slot monitoring program will be initiated in Japan effective S20.

The purpose of this monitoring is mainly the calculation of 80/20, misuse of slots and on time performance (OTP). Slot monitoring is divided in two parts; Pre-Operation Analysis and Post-Operation Analysis. The results of the monitoring will be reported at the occasion of Airport Coordination Committee (ACC). The details can be found in the attachement. >> Attachment

// ATTENTION ALL AIRLINES //

According to requirements set by JCAB, JSC is asking ALL airlines to indicate the reason for slot returns/ schedule cancellations within SI field of your SCR/SMA when they occur after the slot return deadline set by IATA. For details, please see the page Slot Monitoring.
