Hard structures are common shore protection works in Japan. After new coastal law which commenced April 2000 allowed a coastal engineer to use beach nourishment as a legal shore protection work in Japan. However, beach nourishment is not a common shore protection work in Japan yet, even though beach nourishment is standard and preferable shore protection work in US and EU countries. To date, engineering education and qualification systems should be global standard to collaborate internationally, however it looks like that there is still much inconsistency regarding beach nourishment technology and its application in Japan and other developed countries. For instance, beach nourishment project in Japan seems to be small scale and expensive to one of the authors. In addition, beach nourishment is often criticized being short longevity in Japan. Therefore, it is better to compile beach nourishment data in Japan and compareit with US data to realize a reason not to use much beach nourishment yet and hopefully to have future recommendation on beach nourishment project in Japan.
