Why was there a flurry of expansion in imported food shops?

It certainly wasn’t because there was an overwhelming demand from Japanese consumers for Tim Tams and Haribo sweets, because most Japanese still have no idea what those things are. I’m guessing that the main reason was that by buying from importers the shops could miss out those famous Japanese middlemen and so ramp up profits.

Why does a big box of cornflakes in Japan have the writing and picture sideways?

Smaller shelves in the supermarkets??

Not sure why it looks sooooo odd to me either, but might need therapy to work that one out…
