There are items you get from bird messages. At some point, a book seller will be standing in the first area of Konoha and will let you buy a single book. Each book in the list starts a different message chain with a character from Naruto's past. At the end of the chain, they'll attach an item to their last letter.
I think most of those come from missions and events. When you get character's friendship up it triggers friendship events. You'll see a new kind of icon appear above them and watch a scene then you'll get one of the rare items.
