Nobuhiko Obayashi takes another trip into the idol movie world only this time for Toho with an adaptation of a popular shojo manga. That is to say, he employs a number of idols within the film led by Toho’s own Yasuko Sawaguchi, though the film does not fit the usual idol movie mould in that neither Sawaguchi or the other girls is linked with the title song. Following something of a sisterly trope which is not uncommon in Japanese film or literature, Four Sisters (姉妹坂, Shimaizaka) centres around four orphaned children who discover their pasts, and indeed futures, are not necessarily those they would have assumed them to be.
Yasuko Sawaguchi plays the third oldest sister and more or less protagonist of the story, Anzu, who is facing a very common teenage dilemma in that there are two boys (best friends) both interested in her and she can’t decide if she likes both, one, or either of them. Eventually, Yuzuki (Ichirota Miyakawa) wins out leaving his friend Oba (Toshinori Omi) depressed and on the sidelines. However, Yuzuki is from a wealthy family and it was intended he marry a cousin so his mother does some digging and discovers more about Anzu than Anzu knew about herself.
As it turns out, the four sisters are not actually related by blood as only one was the biological child of the goodhearted couple who raised them. Unfortunately, the children’s adoptive parents died in a car accident leaving their birth daughter, Aya (Misako Konno), as a kind of maternal figure to Akane (Atsuko Asano), Anzu, and Ai (Yasuko Tomita) though Akane was the only one old enough to remember their lives before coming to live with Aya and her family. The rediscovery of the truth knocks both younger girls for six, especially as Anzu’s birth mother has reappeared and presents an existential threat to their insular family of four.
Set once again set in a peaceful, countryside town, Four Sisters revisits many of Obayashi’s constant concerns in its evocation of memory, mislaid truth, and the need to come to terms with the past in order to go on living in the present. The four young women are each very different, but bound tightly together by their shared experience, including the recent loss of their parents. Anzu’s discovery threatens to destroy the family firstly through the exposure of a lie (or, what is really an omission of truth), and secondly to speed up the inevitable fracturing as she begins to seek a new life and eventually family of her own. Though Akane has been able to forge a career for herself (less pleasant part-time work aside), she rightly points out that in becoming their maternal figure, Aya has in a sense lost or rejected the opportunity to pursue her own happiness. The sisters’ bond is tight and near unbreakable, but it’s also, in a sense, constraining.
Obayashi begins the picture with in a polaroid-like frame in which the two boys declare their intentions to duel for Anzu’s affections. As the film moves on, Obayshi returns to these intertitle-like captions particularly in bookending the various seasons throughout which the film turns. Though not as radically as in some of his other work, Obayashi once again uses colour filtering as a highlighting tool which is most obvious towards the end as the edges of the screen start to blur, greying out everything other than our central heroines. However, other sequences take place in a noticeably expressionist environment with extreme colour contrasted backgrounds and unreal, star filled skies and Obayashi also allows the real world weather with its storms and raging rivers to dictate the mood.
Four Sisters is, at heart, a family drama though one seen through a slightly distorted mirror. The four girls are indeed a unit which would inevitably have to split or stagnate in the normal order of things but the bonds are strong enough to withstand the unusual amount of pressure placed on them, enabling the sisters to move on with their individual lives whilst remaining close. Obayashi keeps things relatively low key (by his own standards) but gently builds a melancholy, nostalgic tone filled with loss and regret yet also with hope for the future. Beautifully shot, with Obayashi’s characteristically unusual use of imagery and wistful, ethereal atmosphere Four Sisters may not be among the director’s most experimental efforts but does provide a warm tale of love lost and gained in the lives of four ordinary women.
