>>[1] Having taught students from Japan I know that their is a lot of nervousness about speaking
another language. Possibly because Japanese people feel they will lose face if they make a mistake. It is fine to make mistakes as long as you learn something from them. Have you had a look at italki.com ? This is an
international community of language learners and teachers. Maybe you could exchange your Japanese language
for English language or you cuold tale some lessons with a teacher. If you need grammar help have a look at my youtube channel.
