Random observations from a Parisian in Tokyo: Boursin made in Hokaido

3.76€. In general food is much cheaper than in France, except for imported PDO (AOP) food and some common French fruits that are sold as luxury here. For example Comté is 5€30 for 100g, melon can be 30€ for one.

The french flag is a bit surprising given it’s not made in France

It's because the origin is French, it's like having an Italian flag on pasta.

it’s flattering since that means Japanese like french stuff

That's the least you could say, French references are everywhere in Tokyo, food, fashion, building names; it is associated with fanciness.

Those are pretty common in most European countries I've been to too, though often more monochrome. They just seem like less of a hastle than paper tags, if properly implemented.

It's e-ink, like Kobo reader etc. there's a battery in the tag
