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.
