I don't think this is particularly unique to Japan though, eg BBQ culture in the US is similarly masculine.
P.S. - When I was there was told different regions have different takes on different dishes. Some foodie types go cross country to try a specific bowl of Ramen.
Was told this by a woman who was doing precisely that. She also insisted on paying for mine because it wasn't a touristy place and she was glad I was exploring her country.
Anyway I'm not Japanese and certainly can't speak for her but deeply believe she will laugh at this article. A lot. Hence I'd rather a Japanese reader chime in.
It is incredibly easy to read such a thing and just unthinkingly let it contort reality. Japan is Japan, it is not the US.
It's literally includes mascaline Japanese "truck driving" culture with a heavy dash of western cowboy overlay and a women determined to be the best Ramen Chef possible - with a whole lot more thrown in.
But yes, local film, many years ago, already juxtaposing a lone woman in a blokey bloke male heavy culture for comedy and other angles.
