Chapter 25: Shell Cottage

Simplified Chinese (Mandarin: China)
贝壳小屋 Bèiké xiǎowū	贝壳 bèiké = 'shell'. 小屋 xiǎowū = 'cottage, small house'.	Shell cottage
Traditional Chinese (Mandarin: Taiwan)
貝殼居 Bèiké-jū	貝殼 bèiké = 'shell'. 居 jū = 'dwelling'.	Shell dwelling
Japanese
貝殻の家 Kaigara no ie	貝殻 kaigara = 'shell'. の no = connecting particle 家 ie = 'house'.	The shell house
Vietnamese (Chinese characters show etymology)
Chòi đất	chòi = 'small thatched cottage'. đất = 'earth'.	Small earthen thatched cottage

The Vietnamese gives a slightly freer rendition.

Although both Chinese and Japanese use the characters 貝殼, the Japanese uses the native kun-reading, not the Chinese-derived on-reading.
