De vierjarige Kun-chan kan maar moeilijk omgaan met de komst van zijn zusje Mirai in het gezin. In de achtertuin van zijn ouderlijk huis vindt hij een toegangsdeur die hem toelaat terug in de tijd te reizen en zijn moeder als een klein meisje tegen te komen.
Nee, helaas is Mirai no Mirai nog niet beschikbaar op Netflix in Nederland.
