I've discovered a source of Japanese paper that is now being coated for inkjet printing. The Awagami Factory is so nice they will actually send you a sample pack from their factory in Japan. The coated 70 gsm Kozo is much sharper and the blacks are immensely richer than any uncoated Kozo I've used. The website is a wealth of info, and beautifully designed as well-just what you would expect. I am such the Japanophile.
Here's a haiku of Basho's-
The village is old;
No house
Without its persimmon tree.
