In response to increasing tensions with China, Japan is developing unmanned boats for its Coast Guard. This initiative has been spurred by heightened activity of China in disputed waters, and Japan seeks to strengthen its maritime security through technological advancement. The timeline for the development and deployment of these unmanned vessels has not been specified yet.

Japan has always placed a high value on its maritime security, given its status as an island nation and the ongoing territorial disputes in the East China Sea. This move underlines the growing concern in Japan about China’s assertiveness in the region. The development of unmanned vessels represents a significant technological leap in Japan's defense capabilities, and is garnering public interest and support.

In the US and EU, the development of unmanned maritime vehicles is also a topic of interest, primarily for their potential use in enhanced surveillance, search and rescue operations, and defense purposes. Similar to Japan, these advancements are viewed as crucial tools in maintaining territorial integrity and national security.
