Utagawa Toyokuni, Japanese, 1769–1825 Izumiya Ichibei (publisher), Japanese Perspective Pictures (Ukie) from Act 7 of Chushingura (Chushingura shichidamme no zu), ca. 1788–1795 woodblock print housed in a Kato frame.
Estate of Regina Doi. Regina Doi started collecting the Mori's from the late 60's through the 90's. Mori was no as well known but he became famous during the 80's and by the 90's, his works were hard to come by. All the Mori's came from Kato Gallery, who also framed them. Kato and Mori were friends and thus the gallery had first pickings of his works. Regina Doi loved Mori and she may have been his largest collector at one time.

The other prints, namely the antique Hiroshige, Utamaro, etc. were most likely bought from the Oriental Bazaar. This was like a mall of vendors which sold Japanese goods. It had 4 floors of vendors, the first 2 floors were mainly junk but on the 3rd and 4th, they had oriental rugs, prints, jewelry and antiques.

Good prints and antiques were a lot more available during the 60's & 70's. By the 80's onward things were getting more scarce and harder to find. Tokyo was a magnet for these things, it had the population and wealth and so many ended up there.
