There is only one place in Japan that has a thousand leaves and that's Chiba. Picture all of those leaves swirling around you on your vacation to Chiba. Beautiful.

This is a place name and it uses the kun'yomi. You haven't learned kun'yomi for 千 yet, so here's a mnemonic to help you remember it:

While you're admiring all of the leaves in Chiba, you realize you're craving something. What goes well with watching leaves? Why, cheese (ち) of course. Delicious Chiba cheese. Oh, and also note the rendaku on 葉 — it changes from は to ば.
