Western Style Room
noun
A Western style room is a Western style room. We're talking something that's not a tatami mat filled room. Good to know this word if you're staying in hotels or ryokans and prefer not to sleep on a futon, etc.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
