The Cannes Film Festival takes place between May 08th and 19th and the official selection was announced earlier today. Now, it is entirely possible that more Japanese films will be added so I’ll update this list if and when it happens.
Without further ado, here are the films!
Competition
There are two Japanese films in the Competition section so far both of which come from veteran directors with lots of strong dramas to their names.
Shoplifters 
万引き家族 「Manbiki Kazoku」

Hirokazu Kore-eda is a legend who has appeared at Cannes with films six times in the Competition and Un Certain Regard sections, picking up the Jury Prize for Like Father, Like Son (2013). Due to his focus on families in films like I Wish (2011) and Our Little Sister (2015), he is often called the Ozu of modern Japanese cinema by critics and this one features an unconventional family by normal Japanese standards.
Synopsis: Osamu (Lily Franky) and his wife Nobuyo (Sakura Ando) live with their son Shota (Kairi Jyo) Nobuyo’s younger sister Aki (Mayu Matsuoka) and their grandmother Hatsue (Kirin Kiki) in a home behind an apartment. Osamu works as a day labourer but they rely on Hatsue’s pension and the ill-gotten goods they have from their shoplifting antics. They may be poor but they are happy.
One winter, Osamu and Shota find a girl named Yuri (Miyu Sasaki) in the freezing cold and take her home with them much to Nobuyo’s ire but she soon starts taking care of their new family member. However an incident occurs and a family they were on good terms with falls out with them causing secrets to be revealed…

Making his Cannes debut is Ryosuke Hamaguchi who has had a long career as a film-maker but many people will probably know him for Happy Hour (2015). He has a good cast including Sairi Itoh (Love and Other Cults).
Synopsis: Asako (Erika Karata) is a 21-year-old woman who lives in Osaka with her boyfriend Baku (Masahiro Higashide), a free-spirited man, but when he disappears he leaves a permanent shadow in her memories.
Two years later and Asako now lives in Tokyo where she meets a salaryman named Ryohei (Masahiro Higashide).
