The route from Shunan to Chikugo is primarily served by the Limited Express Yufuin no Mori train, which offers a relaxing journey through the scenic countryside of western Japan. This train operates at speeds of up to 120 km/h (75 mph) and typically completes the journey in approximately 2 hours and 30 minutes. The Yufuin no Mori features comfortable seating arrangements and panoramic windows, allowing passengers to enjoy views of the rural landscape.
On the other hand, the regional Minami-Kyushu Limited Express also services this route but takes slightly longer due to more frequent stops, covering the distance in about 3 hours.
Both services provide a unique travel experience, but the Yufuin no Mori is preferable for those prioritizing speed and scenery, while the Minami-Kyushu Limited Express is suitable for travelers looking to explore more stations along the route.
