"To act in a language that I’m not fully immersed in, not fully fluent in, it does pose a bit of a challenge. It does have some good in it as well; there are pros and cons actually. But I do believe if there is a point that I could just be acting like I would in Japanese, but in English, I’m sure that would be so much fun and exciting. One major challenge is that I can’t just do an ad-lib, I can’t do it off the cuff, so really that’s the difference. But it is exciting."
