Mika manages game development and Mastiff’s Japan office. Her motto: Always Forward. Always smile. She resides in Tokyo with her husband and their long-haired dog. She enjoys walking with dogs, skiing, playing wadaiko (Japanese drum), eating, and working at Mastiff! Recently, Mika started playing piano.
