Tomoe River FP (52g/m2) Notebook by SANZEN, 5.85" x 8.27", 160 pages (80-Sheet), Soft Cover, 5mm Squared, White (SR-A5NB-HW)

Are you by chance using Tomoe River paper in a Hobonichi? I’m still have issues with their batches. Your writing sample looks like you got a defective batch if you’re talking about feathering and potential bleed through. I got a notepad that’s from the manufacturer (Sanzen Tomoe River) and they are sooo much better. It’s pretty affordable on Amazon.
