EASY (IER) KANJI - JLPT 4 KYUU

This is a combination of kuchi () [mouth] & tama () [ball]. Sometimes if the parts that make a kanji are strange it becomes actually easier to remember! So get a ball stick it in your mouth and think of your country!  You can also think of something being contained by boundaries (countries are lands separated by boundaries).
Stroke order:

1) koku, 2) kuni - country, a nation

韓国 kan koku - Korea
外国 gai koku - foreign country
中国 chuu goku - China
