The Wajinden (c. 290) notes that slaves (生口) were kept in the area and the island's name may come from this. In The Inland Sea, Donald Richie describes the island as “a smaller Sardinia, a greener Corsica”. The main crop on Ikuchijima today is citrus, and the island is now known as "lemon island of Japan".[2]
