The route from Imabetsu to Tokyo is primarily serviced by the Limited Express trains, specifically the Super Hakucho and the Limited Express Soya. The Super Hakucho typically operates at speeds ranging from 120 km/h to 130 km/h (75 mph to 81 mph) and takes approximately 4 hours and 30 minutes to reach Tokyo, making several important stops along the way, including Hakodate and Shin-Aomori. On the other hand, the Limited Express Soya offers a similar journey time, completing the trip in about 5 hours, with fewer stops. While neither train reaches the speeds of Shinkansen options available on other routes, both services provide comfortable seating and onboard amenities, catering to various passenger needs. The Super Hakucho is preferred for its faster travel time, while the Limited Express Soya allows a more leisurely experience with scenic views.
