Let me tell you another episode of my life on how to turn bad luck into good one. Or how I will always arrive at my destination even when things go wrong.
Two hours from Noboribetsu the train arrived at its terminal station, Hakodate. It is possible to transfer to a different limited express heading to Honshu via an underground tunnel. The left train serves between Sapporo and Hakodate, the green one to Aomori on Honshu.
