I used to teach a lesson about holidays to my student during which I taught them the term "Hallmark Holiday". The awesome thing for Japanese companies is that they not only had their own versions of these types of holidays, but also were continuously folding in more Western holidays. The potential for profit would bring a tear to the eye of a
Ferengi (if you're not dorky enough for that reference and too lazy to read the Wikipedia page I've linked to, substitute "capitalist pig" for "Ferengi"). In my last several years in Japan, I had noticed that there was an effort being made to insinuate Easter as a holiday into Japanese culture. I'm sure that it will eventually be just as successful as Valentine's Day as the year's go by, as a hollow mockery of a holiday that gets people to open their wallets even though their hearts are empty.
Mother's day is the next Hallmark Holiday on the horizon and Domino's Japan has an unimaginative offering for those who prefer to phone in their gift and have it delivered to mom's doorstep. They're selling a small heart-shaped pizza with a simple topping of tomato sauce, pepperoni and mozzarella for 1300 yen ($16.29). The size isn't given, but it says that this is good as 1 or 2 servings so it must be pretty small. I guess that it would be considerate of Mom's health not to feed her too much pizza.
