Prime Minister Shinzo Abe wants to demonstrate the "openness" of his government and to this end has invited schoolchildren on a guided tour of his office and official residence Saturday.

In a historic first for the general public, people will be allowed to enter the official residence, whose origins date to 1929. A new complex incorporating both the prime minister's office and residence debuted in 2002.

About 40 children from Tokyo's Kojimachi Elementary School and an equal number from its junior high have been invited to the two buildings in the Nagata-cho compound, Chief Cabinet Secretary Yoshihide Suga said.
