He was named by Iehisa to a number of prominent positions within the Satsuma han domainal government, and a letter of congratulations from Prince Gushikawa Chôjû of the Ryûkyû Kingdom, likely dating to around 1634, survives in the collection of the Kagoshima Prefectural History Museum (Reimeikan) today.
