Hi there,
New to this website and I’m wondering if there is a way to change the romaji in the lessons to Hiragana/Katakana? I’ve been studying Japanese for a while and just came back from a 2 year stint in Tokyo but I want more practice because my level is still low, however I learned Hiragana and Katakana over 3 years ago and know it well, I find romaji an annoying crutch, anyway to change this?
Thanks! 
You need to specify which course. All the Japanese courses I’ve seen are in either Hiragana or Kanji.
If you’re talking about this course:
Then you need to know that it starts off with Romaji then trasfers to Hiragana. You can just ignore the Romaji words.
The lower level course ask you to type in the answers as Roman, the higher level ones are Hiragana, with the odd Katakana. It is a matter of getting the right course. But, seeing as you have spent time in Japan and done some Japanese, you should not have a problem with the lower level courses, just skip them. They are Basic anyway, but if you do want or need to start, try the second course, the one that follows on from the one Ryou Bakura has shown you for an example.
