Japan is on constant alert against neighbouring North Korea which has conducted two underground nuclear tests and more than 20 missile launches this year.
Under the new budget, the ministry aims to beef up Japan’s ballistic missile defences, allocating funds for a new interceptor missile under joint development with the United States.
Also reflected in the spending is Tokyo’s determination to defend uninhabited islets in the East China Sea — administered by Japan as the Senkakus but claimed by China as the Diaoyus.
