Why the Little Sister is an “Osaka Mama” is a Little Sister

Boku no Imouto wa “Osaka Okan”, or, My Little Sister is an “Osaka Mama” is an odd anime. Ostensibly about a younger sister who grew up in Osaka having to move back to Tokyo, this (sparsely animated) show is actually a way of showing various cultural differences between the two cities. It’s a funny little series, with the ever-changing ending theme based on the events of each episode being a highlight, but what I find especially funny about this anime is its origins.

Boku no Imouto wa Osaka Okan actually comes from a series of books designed to educate people about Osaka customs. The first book, Osaka Rules (as in “to live by,” not as in “Hulkamania”), is itself part of the Rules series for various parts of Japan. It was followed by Osaka Okan, which was designed to help people marrying into Osakan families to understand and deal with their in-laws better. What this means, then, is that the “little sister” component was added specifically for the anime, as if to try and capitalize on current otaku trends. I certainly can’t think of any other reason.

There’s something unbelievably shameless and perhaps even tongue-in-cheek about this that I can’t help but clap in admiration rather than hang my head in shame. Sure, little sister-focused stories are a dime a dozen in light novels, but what if the scope was widened in the way that Boku no Imouto wa “Osaka Okan” has shown us?

The possibilities, as they say, are endless. I’m also aware that this sort of parody joke exists already, but I think the key difference is that the little sister component should appear deliberately grafted on, rather than being the axis upon which an anime revolves.

By the way, this show is from the gdgd Fairies people so you know it’s good.

    • And that is a pretty accurate estimate of this show in my opinion!

      Personally I’m still waiting for What If My Sister Read Drucker’s “Management”?


      • Hisui: Like omo said, that’s essentially the point. And I still find it awesome that the seiyuu who’s actually from the Kansai region isn’t the one who plays the little sister here.


  1. I often thought the intro to each episode was openly mocking the whole ‘imouto-fetishism’ of other shows. Especially the thing about shaving her back or being constipated.
