Sea-lane protection repeatedly arose in conversations with Japanese naval and coastguard contacts. In a Sasebo bar, a civilian proprietor also connected maritime imports with Japan's survival and said she had learned the phrase sea lines of communication at school. It is unclear how widely Japanese schools teach that idea, and this conversation cannot establish a nationwide pattern. The contrast drawn with British school conversations remains an anecdotal impression. The episode illustrates why protecting the routes that sustain Japan belongs alongside screening the home islands in the JMSDF's mission.
