I've been printing on both inkjet coated and uncoated Awagami washi papers for at least 10 years. And I've printed on all kinds of washi paper (primarily from Japan) since 1980.
You either love washi or you don't love washi. These papers are not something you feel ambivalent about. One of the remarkable things about uncoated washi paper is how well it takes inkjet. Western made papers without inkjet coatings print very soft and muted. Uncoated washi has a beautiful sheen to it and allows the ink to set up rather than sink deep into it as would uncoated western cotton papers. That is part of the allure of printing on washi. When they are inkjet coated you can expect deeper blacks, bit more sharpness, and of course a bit more color saturation.
Most of the Awagami line up is extremely thin. Where a typical western inkjet paper is minimum 180gsm, most washi is less than 60gsm and many are under 20gsm. Their thinness is not a deterrent to ink retention. Some of the more recent Awagami papers like Biazan, are incredibly thick
All of them benefit by custom profiling.
If I were you I would request paper samplers from Awagami and also try Hiromi papers in California. Hiromi imports papers not only from Awagami, but from nearly 100 paper mills specializing in washi. Usually these samplers are inexpensive and feature a sheet of letter sized paper. Do not shy away from uncoated. Try printing the same image on each sheet and look at them on the wall as well as by putting a bright white or a black sheet behind them (especially the thinner sheets.)
