on the second floor of the hotel new otani, this place has been an absolute lifesaver. i was able to buy 2 liters of bottled water here this morning for under 200 yen, so i was finally able to get over the severe dehydration i've been experiencing since the plane ride. other things i've bought here include an umbrella, a prepackaged coffee ice cream cone, and yet more bottled water.
konbini are so much better here than what you'd find in an american gas station or convenience store. a) VERY low prices, b) relatively great food, c) a nice variety of other daily necessities. i will miss them so much.
