Clementines ¥398

Chestnut cream and peanut butter. Japanese peanut better is totally different from American peanut butter. It's harder to spread and not as creamy. Also, there is not much of a peanut taste; to me, it just tastes like sugar paste.

wakame onigiri and plain yogurt.

If you come to Japan, make sure you have an adapter. All the outlets here are two-pin. But I guess if you don't have one, you could always buy it here..

And if you decide to stay at DK House Warabi, you're going to need one of these power strips because there are only two outlets in the room, both located on the wall of the window. Even though there are two, though, you can only really use one, since the other one is located next to the desk and the space between them is so small that it's impossible to plug anything in.
