This is my first time sleeping in a Japanese-style room.
Don't you think this Japanese-style room smells like a mix of dog food and your feet, Koichi?
My older brother has a huge pet spider in his Japanese-style room.
A Japanese style room tends to be pretty small. This mainly refers to the kind of room that's covered in tatami mats, though. If you're looking for places to stay in Japan, a 和室 will be something like that. You'll pull the futon out of the closet and sleep on the floor. So comfy, these Japanese style rooms!
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.
