Since the 2010 Senkaku boat collision incident (collision of a Chinese fishing boat into Japan Coast Guard patrol vessels), there have been a series of approaches by unidentified ships and spy ships as well as numerous large-scale marine accidents. Because of these incidents, the importance of the Japan Coast Guard (JCG), which protects Japanese waters, has been increasing to a significant degree. However, the scale of the JCG is very small, with the number of full-time personnel being about 13,000 and the budget being around 180 billion yen. It is essential to strengthen the functionality of the JCG in order to protect Japanese national interests.
