The government is poised to create a special category in the budget to develop public infrastructure such as air and sea ports for defense purposes, according to government sources.
The category is expected to be included in the defense-related budget, which the government aims to increase to at least 2% of the nation's gross domestic product in five years.
The government hopes to develop air and sea ports on islands in the Nansei chain, where civilian evacuations and the deployment of Self-Defense Force units are expected to be required in the event of an emergency, according to sources.
