About Tomoe River Paper:

About Tomoe River Paper:

This notebook uses Tomoe River S paper. The "S" stands for Sanzen Paper Manufacturing Co., Ltd. When Tomoegawa (the original manufacturer of Tomoe River) discontinued its production, Sanzen stepped in to fill the void with an incredible new paper inspired by the original.

Confusion exists because there were three different papers to use the name Tomoe River at the 52gsm paper weight:

  1. Discontinued "Original" (aka "Old") Tomoe River produced by Tomoegawa on Machine No. 7. 
  2. Discontinued "New" Tomoe River produced by Tomoegawa on Machine No 9. 
  3. Tomoe River "S" produced by Sanzen 

Tomoegawa made two Tomoe River papers. When they shut down Machine No. 7 and moved production to Machine No. 9, they created a new paper with diminished performance. This short-lived paper was referred to as "new" Tomoe River and the paper from Machine No. 7 became known as "old" or "original."

Tomoe River S is a new paper not to be confused with the "new" or "original" Tomoe River.

Similarities to the original Tomoe River:

  • Ultra thin and super light 52 gsm weight
  • Phenomenal performance with fountain pen ink
  • Exceptional drape

Differences from the original Tomoe River:

  • Improved opacity (less ghosting) due to pulp impregnated with white pigment
  • Enhanced resistance to bleeding
  • Crisper surface
  • Higher tensile strength (harder to tear)
  • More porous paper surface
    • Slightly faster dry times
    • Increased feedback (still smooth)
    • Less line smoothing
    • Reduced line spread
  • Increased performance with rollerballs

As writers, journalers, and notetakers, the biggest difference in our experience is the feel of the paper. The "original" Tomoe River is smoother and more crinkly, like onion skin paper. Tomoe River S is smooth but feels more natural. In our opinion, Tomoe River S is less polarizing and easier to use daily while maintaining (and in some cases improving upon) the performance of the original.

Great notebook for fountain pens

Tomoe River Paper is the best for fountain pens. The bound notebooks from Papermind well made and the binding lays flat for writing.

Fantastic Notebooks

These notebooks exceeded my expectation. Tomoe River is my favorite paper but I really like 7mm ruled as well. There are not a lot of Tomoe River notebooks that are ruled and I was happy about these ruled notebooks. Plus the ruling is the best ruling I’ve seen in a notebook. The lines are a very soft gray and subtle. I would definitely recommend and I will buy from the PaperMind again!

A Welcome Addition

I am fairly new to journaling on a daily basis. Nearing the completion of a Leuchtturm1917 with dotted lines. I started looking into other options. Intrigued with the Tomoe River Paper notebook from The Paper Mind, I decided to give it a look.
First, the smoothness of the paper feels like glass. When I did a writing sample on the first page with a Pilot Prera fountain pen there was no skipping or bleed through. While the text is visible on the opposite side, it is no different than the 1917. There was no scratching feel with the pen.
Second, I was shocked that with 400 pages it is essentially the same overall thickness as the 1917.
Third, the slightly wider line spacing to 7mm is something I am looking forward to using. The narrower line spacing on the 1917 just felt a little to cramped for my writing style.
Really looking forward to using the notebook in 2025.

A True Premium Notebook

This Paper Mind premium notebook exceeds all expectations. I have used notebooks of all types for years, but this notebook is a cut above all. Its overall construction and attention to detail are exceptional, as is its quality Tomoe River paper. The blotter sheet is another mark of excellence and attention to detail. I might have to buy another one. I should also mention how thoughtful it was for Paper Mind to enclose a handwritten thank you card from Blake- it was a lovely touch.
