The news highlights a series of attacks happening in China that have prompted Japanese schools in the country to increase their vigilance. The incident has raised concerns about the safety of Japanese students in the region, prompting a nationwide call to action to ensure students' wellbeing.

The safety of Japanese students, especially overseas, is of paramount importance to Japan. Beyond immediate family concerns, it's also a matter of national interest tied to Japan's international relations and its reputation as a protector of its citizens abroad. Legally, it places a heavy burden on to ensure the protection of its citizens abroad, and such incidents can influence diplomatic exchanges with concerned countries.

In the US or EU, similar situations are also treated with utmost seriousness. Government bodies usually issue travel advisories, and corresponding efforts are made to ensure the safety of their citizens abroad. They liaise with respective governments to provide protection to their students or citizens and offer support as necessary.
