Marathon in Japan had the first running boom in late 1970, and the second running boom took place in 2007 when Tokyo marathon had started.

By the way, 12 years have passed since 2007 when the second running boom started, and how in comparison with that time did marathon in Japan change? In this study, we tried indication, consideration over the change. The results are as follows.

One of the big changes is recent international marathon interchange. The development of LCC, price reduction of air fare has been happening since around 2012, and runners in Japan has been going out to run in foreign countries. On the other hand, overseas runners have been coming to Japan to run, too. Foreign runners from Taiwan in particular are coming to aim at big city marathon such as Tokyo marathon or Osaka marathon. Marathon in Japan is changing administration with it, too. It may be said that citizens' marathon has become tourism.

In addition, Japanese runners aiming at six great marathons of the world, the world marathon major conquest, have increased, and adds variety in purposes to run for the principle of time supremacy which used to have been seen in citizen runners. Japanese runners feel generosity in overseas races, so they may be possible to bring it into Japan in the near future. The word to "Ganbatte" that was used a lot in supporting marathon may change into words such as "Bravo"
