The Limited Express Sonic is a JR train that makes several convenient stops in the island of Kyushu. If you are traveling in southern Japan with a JR Pass, Kyushu Pass, or North Kyushu Pass, this express train is a great way to access some of the top spots quickly and efficiently.
The Sonic ends in Oita, a large but unremarkable city, but before that it stops at Beppu Station. Beppu is a coastal town, home to countless onsen (hot springs), as well as unique “hell springs” with fantastical colors. From Beppu Station, you can also access Yufuin, another elegant and famous hot spring area.
From one end to the other, the Sonic makes about a two-hour journey. If you are traveling with a JR Green Car Pass, the green car has extra comfortable seats and a panoramic view!
