Hinari

Hinari (pronounced with a silent h) or Inariran as it's known natively, is an artlang based on the idea "what if the Romans colonised Japan?". How did the Romans get to Japan? What are the logistics? Easy. There is no 'new world' in this version of Earth and the Romans simply sailed west. You may be thinking: the Romans could barely conquer Britain, how could they conquer Japan? How did they travel so far? This is even more improbable than them colonising Brasil! Well, I tell you this in response: it just works. If it didn't work, there would be no conlang, and I want to make it. This "Japan" isn't really the Japan of our world, but rather a rough amalgamation of Korean + Japanese + Ainu + Siberian Tartar culture. Why though? Mostly because "Latin but with open codas and Japanese influence" would just look like a transcription of Latin into Japanese, and that's not very creative.

I am taking quite a bit of artistic liberty with creating this language. The outside influences of the language will roughly look like this by the end: The 'other' is mostly Chinese, Greek, English and French.

Classification
Inariran is an agglutinative Japonic language spoken on several islands in the Sea of Japan. Despite originating in Japan, it has significant influences from Latin (sharing almost 60% of its vocabulary!), Korean, Chinese and (theorised) the Siberian Tartar and Ainu languages. It is believed that the language originated as a creole when the Romans conquered the islands in the 2nd century. Also known as Iamata in Latin, derived from the ancient name for Japan Yamatö or Yamatai, the language is written in three forms: Ratina (Latin alphabet), hanra (Hangeul), and yamana (Katakana). There are historical records of the Inari creating their own script from the Latin alphabet once connection was cut after its collapse, however, the script has fallen into obscurity since the feudal ages, in favour for Chinese characters (sonna) and the Latin alphabet in the modern age.

Allophones
Aspirated affricates and fricatives become voiced intervocalically and aspirated plosives always become voiced before vowels. /n/ becomes /m/ before a vowel, /w/ becomes /β/ and /h/ becomes /ɦ/ (/x/ intervocalically). /ɾ/ becomes /l/ word-initially.

Vowels follow a special pattern depending on stress:

Phonotactics
C(j)V(N), where 'j' is a semivowel and 'N' is a nasal, like in Japanese. I know, boring, but this is the sound I am trying to go for: a weird Japanese/romance hybrid.
