This word uses kun'yomi readings, possibly because of 口, which is a body part (body parts do that quite a bit in words and kanji). You should hopefully have seen both the kun'yomi readings from previous levels meaning you can read this word as well. Just watch out for the rendaku that changes くち to ぐち.
There’s someone doing a street performance at the station’s east exit.
The photo taken at the east gate is a bit blurry, probably from the camera shaking.
In the case of an emergency, please evacuate the building through the east exit. There will be coffee and donuts waiting for you there.
