After extensive research on Kyushu, I found that a bus tour is a hundred times more convenient than independent travel, which involves complicated transfers! No need to scramble for Yufuin no Mori train tickets or transfer between JR lines; everything is arranged for you. The view from Daikanbo Peak is superb, and if you're lucky, you might see a sea of clouds. Aso Shrine is quiet and ancient, with its 'marriage pine' and sacred spring creating a wonderful atmosphere. Yufuin offers fairytale shops, the No-Face character stand, and the entire Kinrin Lake area, with plenty of freedom to find desserts and snacks.
