I see it more as a family-positive ad. I don't know the situation in Japan, but in the US, that's a bold move.

While I'm no fan of big corporations, promotion of the family unit is a pushback against the leftist agenda to break down community, family, and identity. To make the individual dependent on the totalitarian state, a mindless consumer, and completely manipulatable through propaganda.

You being part of a happy family is a big middle finger to the matrix, whether you know of it's existence or not.
