One thing that is known for Nagai is the train. They call this train the Nagai Flower Line. This diesel powered train starts from Arato station to Akayu Station and back. There are two trains on this line which are a one-car train and a two-car train. This line is not part of the JR line since it is owned by a private train company. The train is mostly used by high school students and people who have no car like me. The train starts from 5:59 in the morning and the last train is at 8:08 pm if you want to go to Akayu. This train was also featured in the Japanese movie "Swing Girls" and also featured in a famous Japanese detective drama. If you have the chance, take a ride on this train.
