In Japan, servings can be generous when it comes to ramen, the traditional broth-based dish with noodles, pork slices and fermented eggs, characterized by the famous fifth taste, umami. Although it's frowned upon in Japanese culture not to finish your plate, that's not always easy when the bowl is way too big. But now, Japan seems to have found an innovative solution to stop wasting leftover ramen...

In Miyazaki Prefecture, on the southern island of Kyushu, an old railroad line, the Takachiho Amaterasu Railway, takes visitors on a voyage of discovery through the lush green scenery of a peaceful and unspoiled Japan. The railway line is famous in the country for its passage over Japan's highest railway bridge. Anyone with a fear of heights might want to give it a miss!
