Peace and Prosperity.

Explanation:

Sakoku was the period of 'national seclusion' of Japan from the 17th to the 19th century. The word 'sakoku' literally means 'chained nation'.

Sakoku was imposed as a national foreign policy by Tokugawa Shogunate under Tokugawa Lemitsu. Under this policy, no Japanese were allowed to leave the country, if they left they will be put to death. And only a few foreign nationals were permitted to enter the country.

The effect of sakoku on Japan was that they were able to avoid war with their neighboring nations such as Asia. And through the enactment of this policy, they were also able to stop Mongols from invading their lands. The seclusion helped Japan to improve its economy because of the peace with the neighboring countries.

So, the correct answer is peace and prosperity.
