Tayuemon Tadashige was a tsubako of the Akasaka school, the lineage of makers who relocated from Kyoto to Akasaka in at the beginning of the period and flourished there until the end of the Tokugawa shogunate. Tadashige entered the workshop of the fourth-generation master Tadatoshi during the latter's final active years; in practical terms, however, his training was conducted under the fifth-generation Tadatoshi. He proved remarkably long-lived, with signed works from his later career bearing the inscription "made by Tadashige at the age of eighty-four," and his skill has been praised as among the most accomplished of the Akasaka masters active from the mid- period onward. His eldest son, (忠好), is known to have executed - works on his behalf in these advanced years.

Across the designated works, the evaluative language is remarkably consistent: "large in scale and dignified," "strikingly innovative," "exceptionally well-balanced and notably distinguished." Tadashige's achievement lies in his synthesis of Akasaka orthodoxy with an enterprising creative spirit, producing openwork of "pronounced dignity and distinction" that the regards as fully displaying "the characteristic strengths of Akasaka work, whose true specialty is a stylish and tasteful openwork aesthetic."
