In the past, I wrote several guides, mostly pertaining to Japanese Self Study that people who are learning the language either through self-study or class instruction might be interested in.
Newcomer’s Guide to Importing and Using Japanese Games as Practice – If you are interested in video games and want to use them as a form of practice, this is the right way to do this. (The same techniques can be used for Manga and Light Novels as well).
Journey of Self-Studying Japanese – Honorific Expressions – An analysis of honorific speech and when to use them.
Journey of Self-Studying Japanese – Study Strategies and Technology – Mostly geared to self-study. Basically consists of programs and sites you can take advantage of to study and practice what you learned.
Journey of Self-Studying Japanese – Casual (Short) Forms – Analysis of casual speech, usually not covered that much in formal study.
Journey of Self-Studying Japanese – Tackling Verb and Adjective Conjugations – Mostly how to conjugate verbs and adjectives (should already be covered in class and textbooks)
