Nobunaga and Onion

Nobunaga was known to try foods that Europeans brought over to Japan.  He might have been the first Japanese to eat an onion.  http://www.asagei.com/25356  Jesuit missionary Luis Frois brought an onion to Azuchi Castle.  The onion was prepared with rice.  The onion might have arrived much later in 1770, in Nagasaki.  What the case maybe, Nobunaga might have had a sample of this famous vegetable.
