Application Engineer Salary in Tokyo

I'm an experienced Android software engineer. I moved to Tokyo a little while ago and am looking for a new job. I got an offer which is a third as much as I was making in San Francisco. I know it is a very different market here, but it's pretty hard to swallow. I also don't have a big background on what people are making here to know if it is in the right ballpark.

What are experienced engineers at start ups making?

What about other compensation?
