Kimitachi wa Dou Ikiru ka

They're both directed by Hayao Miyazaki and revolve around a young kid that searches for their parents with some fantasy elements. Spirited Away delves deeper into the word while The boy and the Heron is more of a drama. 

• Both the Oscar winning Japanese animated flims are directed by the legendary director Hayao Miyazaki at Studio Ghibli. • Both are coming of age stories explore similar themes such as grief, family, responsibility, identity, selflessness, and the fear of the unknown. • Like Spirited Away, The Boy and the Heron tells the story of a child who enters a magical world and undergoes a psychological transformation—both films have been compared to Alice in Wonderland, best interpreted through the logic of dreams. 

Unique and non-linear narrative structure, multiple reality shifts, with an unreliable narrator leaving open the question of what is real and what is not. Overlapping time period, and a major theme of legacy.
