Japanese language is somewhat difficult to grasp. Easiest thing is probably by starting by the Chinese characters.
In order to read their pronunciations, it is better to start with “kana” readings. These are two sets to learn, hiragana and katakana.
Once the basic skills in the readings are acquired, next step might be to study the Japanese culture and its hierarchy aspects. Hierarchy is the key to everything which is Japanese.
Good luck. Hard training required.
