Sachie (Satomi Kobayashi) is a Japanese woman inexplicably opening a café in Helsinki, where she thinks the Finns will like Japanese food because they like salmon. After a long month without any business, her first customer, Tommi (Jarkko Niemi) is an anime weeb with a terrible taste in T-shirts, who wants her to write out the lyrics to the Gatchaman theme. Unable to remember the lyrics (because this is an alternate universe where the internet doesn’t exist), she buttonholes a stranger in a Helsinki bookstore. Midori (Hairi Katagiri), knows the song, but is an oddball who has randomly picked Finland on a map, and now has nowhere to stay. Sachie offers her a place to live, and the two women muddle through at the café.

They are soon joined by Masako (Masako Motai), a third Japanese woman who has come to Helsinki to celebrate her “freedom” after twenty years as unpaid carer for her ailing parents. She is the only character whose back-story is really announced in any detail – whatever has brought the others to Finland is kept discreetly off-screen. They are three characters in search merely of acceptance and belonging, finding it in the oddest of places, and clinging, curiously, to a desire to be anywhere but Japan.

“A strange man just gave me a cat,” Masako announces. “So now I have to stay.”

It’s only when I write out the synopsis that I realise just how little happens in Naoko Ogigami’s feel-good film, Kamome Shokudo. The Japanese ladies experiment with new menu choices, and slowly win over the reserved Finnish passers-by in a Helsinki street. These include Liisa (Tarja Markus), an abandoned housewife who has to be carried home after collapsing in a drunken haze. Masako, meanwhile, has lost her luggage, and turns up in an increasingly garish selection of Marimekko dresses while she is waiting for her clothes to show up. Midori doodles some awful pictures on the menu, and Masako goes looking for mushrooms in the forest.

Whereas Master Cheng (2019) was a Finnish exercise in luring Chinese visitors, Seagull Diner is a very Japanese take on the Nordic countries – I am tagging it with my #finnfilms watchathon of every Finnish film ever made, but it is technically a Japanese film that happens to have been shot on location in Helsinki. Ogigami’s characters fall in love with Helsinki’s quaint streets and seaside cycle paths, its city markets and melancholy locals, and, presumably with a surfeit of product placement, since the café is packed with Finnish design classics. There’s no real jeopardy or crisis, just a slow infusion of joy as the ladies experiment with local ingredients, refine their menu, and eventually proclaim that the diner is a success, because it is full of happy Finns.

Ogigami’s script boldly dispenses with much of the whys of her leading ladies’ backstory, taking it as given that they are all fleeing from something, and simply seeking a harmonious, happy life in the land where the Moomins come from. Much in the spirit of My Neighbour Totoro, it’s a resolution that doesn’t see the need for conflict. They remain in a remarkably compact series of locations – huge tracts of the film pass in single locked-off shots in the café or Sachie’s flat, plus what looks like a single day’s shooting down in Helsinki harbour, a bike ride around Töölö, and a pick-up at the airport.

Matti (Aki Kaurismäki regular Markku Peltola) shows up to mansplain how to make good coffee. Apparently, you should stick your finger in it and make a wish, which explains an awful lot about Finnish coffee. He leaves a package of coffee that has been passed through the digestive tract of a civet cat. The Japanese women end up making coffee that is literally made of animal shit, and telling each other it’s lovely. For Kaurismäki fans, this was sacrilege, but for an entire generation of middle-aged Japanese women, marginalised and ignored, it was a wake-up call that they, like Sachie, could do whatever the hell they liked. Or in Sachie’s words: “not do the things I didn’t want to.”

Despite premiering in a single Japanese cinema with very little fanfare, it would become the fifth highest-grossing Japanese film in the year of its release. More than a decade late, it remains a potent soft-power ambassador luring Japanese tourists to Finland.
