Answer:
Japan’s mountainous terrain has led to a clustering of large populations along the coastline, often around seaports. This greater concentration of people along the coasts makes public transportation in the form of metro trains more efficient than roadways. Roads would clog up with cars in a city like Tokyo if people drove themselves to and from work or school each day. According to the article, Japan has no fossil fuels to operate cars, so a more efficient transportation vehicle, like a train, was needed to use natural resources wisely. Also, crowded roadways have led to car accidents, encouraging more people to use the safer transportation option of trains.
