Just who is the Monster?

Saori Mugino is a widow, raising her young son Minato and working in a laundry in a small city in the Nagarno region of contemporary Japan. When the boy starts behaving oddly – and returns home from school one day with an injury – she grills him until he says that his new teacher, Mr Hori, had inflicted it.

Saori goes to the school, demanding action against the teacher, but only receives overly deferential apologies, particularly from the principal, who herself seems oddly distant.

But when Hori himself claims that Minato is bullying sensitive classmate Yori, she becomes ever more determined to get at the truth and the situation escalates.

Written by Yuji Sakamoto and directed by Hirokazu Kore-eda, the story is told three times. First from Saori’s perspective, then from Hori’s and finally, from that of the two boys.

It is subtle, affecting and very sensitive. Kore-eda himself has denied that it’s an example of the Rashomon effect – storytelling centred on the unreliability of witnesses – and certainly it’s more of a jigsaw than an enigma.

There are manifold themes here: respect, acceptance – not least of self-acceptance – bullying, grief and loss, the concept of rebirth in Japanese Buddhism, and the problems that can be caused by overly strict structures.

Kore-eda’s direction is excellent – not least of his child actors. He coaxes an extraordinary performance in particular from Soya Kurokawa as Minato, who won the best newcomer at Japan’s Blue Ribbon Awards, as well as from Hinata Hiiragi as Yori.

Sakura Ando as Saori, Eita Nagayama as Hori and Yuko Tanaka as the school principal also produce fine turns.

The film includes the last music for film written by legendary composer Ryuichi Sakamoto – delicate piano pieces that add to the poignant atmosphere.

Monster’s world premiere was at Cannes last year, where it competed in the Palme d’Or. It won the Queer Palm and the award for best screenplay. It’s not difficult to see why. It is a very special film.
