New textbooks authorized for use in Japanese high schools from April 2018 contain more descriptions on the foreign and defense policies of Prime Minister Shinzo Abe, including the ability to engage in collective self-defense, the education ministry disclosed in the results of its latest textbook screening Friday.

The textbooks are primarily for second-year high school students. Many of them explain the grounds for engaging in collective self-defense — or coming to the aid of an ally under attack —under the divisive 2015 security laws.

As for Japan's territorial disputes with other countries, all eight civics texts screened say that the Takeshima islets in the Sea of Japan, called Dokdo by South Korea, and the Senkaku Islands in the East China Sea are an "inherent part" of Japanese territory.
