A captivating story of love passed down through generations from acclaimed director Mamoru Hosoda and Japan's Studio Chizu. The film follows Kun, a four-year-old boy who is struggling to cope with no longer being the centre of attention following the arrival of a little sister. Named Mirai (meaning 'future'), the new baby instantly wins the hearts of Kun's entire family. As his mother returns to work, and his father struggles to run the household, Kun becomes increasingly jealous of baby Mirai.

One day after storming away from home, Kun stumbles upon a magical garden that transforms into a time-travelling gateway, where he encounters members of his family from the past and future. The young boy joins the mysterious visitors, and they embark on a series of fantasy-filled adventures together which teach Kun to see things from other people's perspective and help him become the big brother he was meant to be. An official selection at Cannes Directors’ Fortnight, Mirai is a beautiful, enchanting, and emotionally soaring adventure about the ties that bring families together and make us who we are.
