KMTC is combining its fortnightly JKW3 and JKW4 Busan-Japan services into a single weekly JKW3 loop. The consolidation upgrades all remaining port calls to weekly frequency, while Nagasaki will no longer be served.
The new rotation covers Busan, Moji, Imari, Yatsushiro, Shibushi and Satsumasendai, before returning to Busan.
