At first hand, Rikokatsu comes across as a lighthearted comedy but I would think it twice before writing it off as just that. Personally, I think this drama presents itself as a easy to watch rom-com but it is full of social commentary about Japan's current situation in relation to their low marriage rates and high divorce rates among older people.
Saki, our leading lady, is a competent fashion magazine editor who comes from a progressive family. Because of this, she's not only committed to her work but values her independence and looks a partner who will respect these attributes. On the opposite side we have Koichi, leading man, who comes from a military family with traditional japanese values. Love triumphs over their differences, at the beginning, but cohabitation makes it impossible to look past some blaring problems in their every day life.
The drama never makes Saki say it out loud but she's clearly a feminist, this is one of the main reasons that catapults the problems in their marriage. Koichi expects from her what his mother did for his father: follow the man's rhythm of life, make all the meals, cleaning, etc. I want to make point out that Koichi it's not misogynist because he does respect Saki and sees her as an equal, in fact, when she calls him out on things he changes his behaviour but it's clear that it never occurred to him that a marriage could look different than the one his parents had. On the other hand, Saki doesn't know how to adapt to some of Koichi needs or behaviour that are absolutely normal as a couple because she's used to her parent's marriage where each person had their own thing to the point of not having family meals together once at home.
I found their situation as a mirror of Japan's society as a whole. Cosmopolitan, interesting, independent but also with a deep rich ancient tradition. These two characteristics seem to complement each other well, at surface level, but the social issues in the country it is proof of the imbalance between the two.
I mentioned that Japan currently has a high divorce rate among older people. Marriages of decades that "suddenly" crumble. Well, both leads' find themselves in the situation of having to deal with their parents' divorces because of all the reasons I wrote about before.
Most of the drama it's about a couple finding a balance and accepting there's not one way to be a family. That marriage can look very different according to the needs of the two people involved in the relationship.
Technically speaking Rikokatsu it's really good. The cinematography really beautiful and camera work a mix of traditional and more dynamic. The performances are really good from all the cast. The leads, Kitagawa and Eita, are full of charm and fleshed out their characters in a compelling way. There are no bad guys, just two people trying to figure out life.
For all of these, I fully recommend Rikokatsu.
