1. つき, tsuki - “moon”, perhaps distantly related to Finnish kuu - “moon” etc
2. たつ - tatsu, to stand, compare Finnish seisoa - “to stand” and also perhaps Quechua sayay - "to stand".
3. から- kara, shell, compare Finnish kuori etc and Quechua qara and other likely cognates.
4. つち tsuchi - earth, compare Finnish hiekka - “sand” or “gravel” etc and many other possible cognates which I have discussed elsewhere. 
5. ゆき - yuki, snow, compare Indo-European *eyg- "ice" or "frost", Scottish Gaelic eigh etc. 
6. へび - hebi, snake, compare the name of the Scythian goddess Api, with serpents or tentacles instead of legs, and possibly the Egyptian goddess Ipy, and for example Guaraní mbói - “snake” and other cognates I have discussed elsewhere that may connect to this root. Other etymologies of the Japanese word are also possible, including a possible connection to a Chinese word, hanbi referring to a kind of medicine. 
7. およぐ - oyogu swim, compare Finnish uida - to swim and Quechua wayt’ay - “to swim”
8. すう - suu, to suck, compare Finnish suu - “mouth”
9. みみず - mimizu, worm, compare Finnish mato - “worm” and other possible cognates discussed elsewhere. Other origins of mimizu are also possible, including a meaning of "eye-less" in reference to worms not having eyes. 
10. かぜ -  kaze - wind, compare the English words "haze" and "gas", the etymologies of which I have discussed elsewhere.

11. ふく - fuku, to blow, likely onomatopoeic with the original root being "fufu-" but nevertheless comparable to Finnish puhua - "to speak", originally meaning "to blow" perhaps in the sense of "blowing" or "wishing" a protection charm.
