The king of Japanese animation has come out of retirement for another feature film. Hayao Miyazaki, the legendary artistic force behind Studio Ghibli, revealed the title of his next– and supposedly, last– film at the opening of the Natsume Soseki Memorial Museum at Waseda University in Tokyo.

The full-length feature animation is called “Kimitachi wa Do Ikiru ka,” which roughly translates to “How Do You Guys Live?” or “How Do You Live?” The project gets its name from a 1937 book from writer Genzaburo Yoshino of the same name. According to the Japan Times, the book will have “significant meaning” for the main character in the film. The book follows the psychological growth of a young boy into a young man via interactions with his friends and his uncle.

According to THR, Yoshino was an editor and writer of children’s literature, who also worked as a journalist and the editor of a prominent magazine. The progressive publication was particularly influential in Japan after WWII.

Miyazaki said of the film:

“The film is about how this particular book featured prominently in the protagonist’s life. It will take three to four years to complete the anime.”

This is the second time Miyazaki has returned from retirement. He previously said that his film “The Wind Rises,” completed in 2012, was his last feature film due to his old age, but announced his return to full-length animation last February. He’s known for his animated films “Howl’s Moving Castle,” “Kiki’s Delivery Service,” “Princess Mononoke” and “My Neighbor Totoro.” He earned an Academy Award for his film “Spirited Away” in 2003.

No word yet on an exact premiere date.
