"The genkan" reminds me of the "all according to keikaku" meme

~では to emphasize that this is a practice in country X not in Y and Z.

It is Japanese style !! (これが日本式！！)

Take off your shoes when you enter, please. Or crawl around on the floor on your .... knees.

日本では、玄関で靴を脱ぎます。

Can someone break down the sentance, please?
