Therefore, it was decided to write Aizan as '藹山' in Japanese using two Chinese characters of '藹' (referring to a wooded and abundant landscape) and '山' (referring to a mountain) instead of Chinese characters '靄' (referring to mist) and '厓' (referring to a cliff) which composed his master's pen name, 靄厓.
靄厓の「靄」（もや）に対して「藹」（樹木が繁って盛んな様子の意）を充て、「厓」（崖・がけ）に対して「山」を合わせて「藹山」とした。
