7 proofs Yotsuba comes from Iceland

So, no one knows where do Yotsuba comes from, right? Well I found out that she is icelandic, here's some reasons:

1. Yotsuba is an adopted little girl from a foreign country: Iceland is a foreign country
2. Yotsuba's parents says at some point in the manga that she comes from an island in the west: Iceland is an island in the west
3. People often mistake's Yotsuba for a foreigner, since she's not black or brown that means she's white: Icelandic people are white
4. Yotsuba has always green dye in her hair, maybe her parents did it to hide her true hair color: Icelandic people are redheads or blondes
5. Yotsuba has green eyes: Icelandic people have the highest rate of green eyes in the world (89% of the population)
6. Since she's adopted, Yotsuba must come from a poor country: Iceland is bankrupted and destroyed by a volcano
7. Iceland rocks!

I said she dyes her hair beacause honestly I dont know a lot of people who born with green hair, even less in juhpan
