I am looking for beni imos which are purple sweet potatoes from the Okinawa region of Japan. I have found satsuma imos/gogumas (in my native Korean) at Sunrise, JAS Mart, etc, but have not seen beni imos anywhere.
Please let me know if you have any tips -- help a sister out! I'm located in Brooklyn but work in Manhattan and am willing to travel to Queens. Caveat: need to get there by public transport/foot as I don't drive. Yes, shameful.
