have you found a way to start on your way to mastering the japanese language ? Or a local japanese aikido school you could go to, while studying japanese ?
If you try self study, will you try to pass the JLPT exam, from the beginner level ( JLPT N5, equivalent to 80-hours study ) to JLPT N1 (high level fluency & vocabulary) ?
you can find some free material on the internet for these, such as http://www.mlcjapanese.co.jp/
It can help to have clear goals ( you pass the exam if you know X kanji, Y grammar rules, ... each level is clearly set ... the first 3 levels do help reach fluency for daily life...)
Have a good day ! (and happy new year)
