In the states. I choose either Best Foods or Hellman’s (my sister has a jar of Best Foods Olive Oil mayonnaise in the fridge and I like it.) In Japan I always used Kewpie because the other Japanese brand of mayonnaise found there was Ajinomoto. I did my best to avoid their products because, at least in the vernacular in Japan, “Ajinomoto” literally means “MSG” and though I don’t have any adverse reactions to it, I don’t crave it or the unnecessary sodium it adds.
I would occasionally buy a small jar of Best Foods or Hellman’s mayonnaise (expensive!) in Japan to make American-style potato salad or tuna salad there, but for Japanese food, especially okonomiyaki or takoyaki, I prefer Kewpie.
