snoichi doesn't exist in Japanese. No such thing as "s". You can have sa, shi, su, se and so, but not just s.
"no" is a possessive modifier.
"ichi" means one.
The closest thing I can come up with would be sunoichi, with the "su" being abbreviated when spoken as is common.
something "noichi" would roughly translate as first something, but that isn't correct. You use "hitotsu" to indicate first. Or a goofy counting system like ikka, ippon, issatsu (i-something depending on the type of thing you are counting).
su means sandbank, nest, rookery, breeding place, beehive, cobweb, or vinegar.
None of it makes sense put together, so I doubt it's japanese.
