I still haven’t been to Shikoku.
Have you gotten used to life in Shikoku yet?
I was traveling through Shikoku to learn how to make the best udon noodles.
The four country is another section of Japan. It's quite nice, too. Look on a map and try to find it. So, the meaning of this word is a also the reading, which you should be able to figure out because it's all on'yomi: Shikoku.
This is a jukugo word that uses the on'yomi readings of the kanji. You've learned them already, so you should be able to read this on your own!
