Out for a stroll last night I stumbled across health and whole food shop 菜花 (na no hana). They have plenty of organic vegetables and fruit here, all kinds of natural cooking ingredients, vegan food supplies and earth-friendly cleaning products. 菜花 sits about halfway between Demachiyanagi and Hyakumanben. If that isn’t convenient, they do deliveries. To find it, just walk east of the Eiden line exit of Demachiyanagi station, past Falafel Garden and further on past the Heming Sports Club until you get to the Omuraya オムライス (omelette and rice) place on your right. Turn right here and go past Kroon Thai restaurant and it’s on your left just before Rico Rico Spanish restaurant. Here is a most convenient map (the red circle marks the spot).
Opens weekdays: 10:00 ~ 20:00
Saturday: 10:00 ~ 19:00
Closed on Sundays and national holidays.
