Seiyu is a supermarket located right by Tokorozawa Station. Daiei, which is further down the road, actually has a wider variety of products. But I usually end up going to Seiyu because it's closer to my side of the station and they're food section is open until 2am. That means I could come back from the city on the last train and still by milk and eggs. Very convenient.
Anyways, I was just really surprised at how many types of mayonnaise there are. So many variety...cut calories, cholestrole free, mustard mix, small obento sizes.
Just so you know, it tastes TOTALLY different from the mayonnaise in the US.
