Nagatsune (1721-1787), 1st generation master of Inchinomiya School in Kyoto, adopted son of the gilder Nagayoshi, student of Yasui Takanaga [M. Sesko 'Genealogies', p. 26].

"What Sōminis in the East (Edo), Nagatsune is in the West (Kyōto)." “Since Nara period, Japanese fishermen in small boats have used cormorants (u) to catch river fish at night, binding the necks of the birds so that the fish are not swallowed. […] The bird and the work it performs are symbols of selfless devotion to one’s master and keen eyesight.” – from Merrily Baird 'Symbols of Japan. Thematic motifs in art and design.' //Rizzoli international publications, Inc., 2001; p. 104. See also in this collection: TSU-241 and TSU-0096
