Selected via a talent competition held in conjunction with the search for a new actress to play the leading role in Kosei Saito’s Ninja Wars, Noriko Watanabe became the second of the new “Sannin Musume” alongside the future star of The Little Girl Who Conquered Time, Tomoyo Harada, and Kadokawa’s top idol Hiroko Yakushimaru. Her career with the studio was however comparatively short-lived affording her only three leading roles before she eventually left the agency and went independent after turning down a lead in Koibitotachi no Jikoku because of its explicit nude scenes. Again adapted from a novel by Jiro Akagawa, Kekkon Annai Mystery (結婚案内ミステリー) was her final leading performance as a Kadokawa idol (though she would also play a supporting role in Obayashi’s His Motorbike, Her Island) and saw her playing a slightly more mature role as a young woman working for a matchmaking agency who finds herself mixed up in a country house mystery after accepting an unusual proposal from a client.
At 19, Hiroko (Noriko Watanabe) is the sole employee at the Fukada Marriage Consultation Agency owned and operated by her boss Mr. Fukada (Bengal). As we first meet her she’s deep undercover at a rival firm which has already shifted into a new era of computer-assisted matchmaking whereas Mr Fukada prefers to do things the old-fashioned way which is presumably why he has no business. It comes as something of a shock therefore when he receives a call from Mrs. Sekine (Aiko Nagayama), the temporary CEO of a major company who apparently wants to find a match for her son Masakazu (Ken Watanabe) who is shortly to return after graduating from Harvard in order to take over the family business following the death of his father six months previously. At the initial consultation, however, Mrs Sekine scandalises Mr Fukada by immediately selecting Hiroko as a potential bride. Seeing as it’s only an initial meeting, which would earn them a bonus payment, Hiroko agrees but when they drive out to the Sekines’ creepy gothic mansion in the middle of nowhere they discover all is not quite as it seems. Masakazu has a fiancée already, but unfortunately she was involved in a traffic accident and is currently in hospital which is a problem because for undisclosed reasons they need to hold the wedding right away. Hiroko is to act as a proxy seeing as no-one who’ll be coming to the ceremony has met Masakazu’s girlfriend and so will be none the wiser.
Perhaps somewhat naively, Hiroko agrees and ends up staying in the house posing as Masakazu’s intended which includes sharing a room. Briefly shifting genres, a training montage sees Hiroko undertaking a crash course in how to be posh, adopting the correct deportment, using cutlery elegantly, and learning to walk downstairs in massive heals or up while wearing an inconveniently long dress. Which is all to say, the fabulously wealthy inhabit a different world of which Hiroko was hitherto ignorant. This is further brought home by the apparent cracks in the foundations of the Sekine family which is also a corporate entity with the other board members largely favouring other candidates more closely connected to the themselves to take over as chairman while apparent liability uncle Masao (Tamio Kawaji), whose creepy crossbow-carrying young son Mamoru is for some reason being raised by Mrs Sekine, is in some kind of trouble with yakuza loansharks. The other main issue is that Mrs Sekine is a second wife and longtime mistress of the late CEO. Masakazu was born out of wedlock and Mrs Sekine will do anything and everything she can to ensure he assumes his birthright.
Counter-intuitively succession intrigue has little to do with the central mystery which begins to unravel when Hiroko is attacked on the eve of her wedding by a strange woman who had previously tried to warn her off Masakazu and kills her in self-defence. The body, which we can identify as that seen buried in the snow in the solarised green-tinted opening sequence, is taken care of by Mrs Sekine’s right hand man Kinoshita (Hayato Tani), but Hiroko begins to have her doubts after catching sight of a woman who looks exactly like the one she killed at the local ski resort.
“Rich people are like that. They’d lie about anything in order to keep their wealth” Hiroko is told, realising she may be at the centre of an infinitely complex plot and becoming aware of Mrs Sekine’s tendency to throw money at people to get them to play along with her plans. Like any good gothic mystery, however, the house holds a dark secret in a hidden room which perhaps hints at the corruptions of the Bubble era along with those of the super rich elite and the undue pressure it puts on its young while uncomfortably suggesting that Mrs Sekine herself is the source of the corruption in her attempt to integrate into a higher social class into which she was not born. Atmospheric in its chilling vistas of the freezing snow, Kekkon Annai Mystery’s twisting tale of greed and manipulation may end in tragedy but ironically lives up to its name as its heroine finds a potential match in her accidental co-conspirator.
