Doing consultant taxes in Japan

I moved to Tokyo this year, and have been consulting for a company. The company will not be assisting me with my taxes unfortunately. HN probably isn't the best place to ask this kind of question, but I'm struggling to find resources online, and assume many of you are at consulting gigs and have the same lack of Japanese experience to do something as tense as taxes.

1) What is the best course of action?

2) Does anyone have recommendations for a cheap, English-speaking tax preparation office?
