I tried some Awagami Kozoshi 91g/m2 and it's vey nice. Much stronger than supposed for a 91 g/m2 paper. Easily brush coated. Need 2 drops more than usual on Arches Platine (I use 14 FO + 14 Pd for a 8x10") and about 1 step more exposure (x1.4). Clear easily.
My normal printing paper is Arches Platine. It's a wonderful paper if you use it at very high hygrometric level, good temperature over 20°C et let the coating rest for 5mn before cold drying back side.
Bad point, sometimes some black points, check paper against strong light before coating.

Here is the Kozoshi paper reference I use from Schleiper:
AW21350016 Awagami Kozoshi - papier japonais - feuille 91g/m² - 97x64cm - 4 bords droits - naturel
AW21350016 Awagami Kozoshi - japanese paper - leaf 91g/m² - 97x64cm - 4 straight edge - natural
