Shigenori's place is just about 300m from Naka-okachimachi station and there are 3 convenient store around this place and even a supermarket. I had great experience tasting fresh fruit from a supermarket nearby. For muslim fellow, the place is located near from Assalaam Masjid and the most delicious halal ramen in town, Ayam-Ya! But the place is quite narrow for 5 of us. It will be more comfortable if only max. 3 people who stay.
