Machine 7 Tomoe River Paper Dupes? Side-by-Side Comparison of 3 Closest Candidates
I recently went to Seattle and bought several different notebooks to test. One of them performed so well with fountain pen inks that it made me wonder: could this be a serious alternative to the original Machine 7 Tomoe River Paper? That question prompted me to do a side-by-side comparison with the OG Machine 7 Tomoe River Paper, and the result genuinely surprised me.
Machine 7 Tomoe River Paper is what many fountain pen users refer to as the original Tomoe River Paper. It is known for its lightweight feel, extraordinary fountain pen ink expression, and excellent resistance to feathering and bleeding. It is also exceptionally smooth to write on, giving many pens that effortless “my pen writes better on this paper” feeling.
For a long time, it was considered the holy grail of fountain pen paper, especially for people who love ink properties such as shading, sheen, shimmer, and multi-chromatic separation. When it was discontinued, it broke a lot of fountain pen users’ hearts. Since then, many of us have been searching for the best Tomoe River paper alternatives.
Several papers have tried to fill the gap left by the original Tomoe River Paper, including its rightful successor, Sanzen Tomoe River Paper. Iroful Paper is also frequently mentioned by fountain pen users as a strong alternative for ink swatching. The third candidate in this comparison is less commonly discussed outside Japan: Neo Agenda paper, used in Mark’s EDiT notebooks and planners. This was the paper that originally made me want to do this comparison.
In this blog, I want to compare these four papers directly and focus on one main question:
Which paper is the closest to OG Machine 7 Tomoe River Paper for fountain pen ink expression?
By “ink expression,” I mean how well the paper shows the visual properties of fountain pen inks, including shading, sheen, shimmer, saturation, line sharpness, and multi-chromatic colour separation.
The four papers compared are:
A. Machine 7 Tomoe River Paper
B. Sanzen Tomoe River Paper
C. Mark’s Neo Agenda Paper
D. Iroful Paper
Blind Instagram Poll Result
Before revealing the papers, I posted a poll on my Instagram account to see if people could identify the Machine 7 Tomoe River Paper from photos of all four paper samples swatched with the same inks.
Interestingly, among 34 people who answered the poll, only 2 people chose the correct answer. In other words, about 94% of respondents could not correctly identify the original Machine 7 Tomoe River Paper from the photos alone.
Of course, this was not a controlled scientific test. Lighting, camera settings, Instagram compression, screen brightness, and individual display calibration can all affect how ink appears in photos. Still, I found the result fascinating because it suggests that, at least visually, modern alternatives have become very convincing. (For those who saw the poll, the samples are arranged in the same order in this blog.)
Testing Method and Limitations
Before getting into the comparison, I want to acknowledge that ink swatches can vary. Differences in ink amount, swatching pressure, drying time, lighting, and photography can all affect how we interpret paper performance.
To reduce variables, I used the same inks and the same type of swatching tool across all four papers. Still, this comparison reflects my own samples and my own testing conditions, so it should be read as a practical side-by-side comparison rather than a laboratory test.
Sample A: Machine 7 Tomoe River Paper — The Reference
Sample A is the Machine 7 Tomoe River Paper reference.
You may not be able to feel the smoothness from a photo, but one signature giveaway in this test is how Nakabayashi’s Opera Rose performs on this paper. Among all four samples, it appears the pinkest and most vibrant on Machine 7 TRP.
This paper also performed beautifully across all the ink properties I tested:
This is exactly why Machine 7 TRP became so beloved. It does not just handle fountain pen ink well; it makes ink look more interesting. The colours appear vivid, shading has depth, sheen is dramatic, and shimmer remains expressive without the paper feeling overly absorbent.
It also has that classic ultra-smooth Tomoe River writing feel. Pens glide across the surface effortlessly, and the paper makes many nibs feel wetter and smoother than they do on ordinary notebook paper.
Sample B: Sanzen Tomoe River Paper
Compared with the Machine 7 TRP reference, Sample B — Sanzen Tomoe River Paper — is, in my opinion, the closest replacement for ink expression.
It replicated the original’s performance very well across shading, shimmer, and sheen. The shading inks still showed good depth, the shimmer inks remained lively, and Waterman Inspired Blue still showed the red-purple metallic sheen that was so obvious on Machine 7 TRP.
If I were judging purely by ink expression, Sanzen TRP would be my top candidate as the closest replacement.
That said, Sanzen does not feel exactly the same as Machine 7 TRP when writing. Compared with the original, it has a slightly more textured or toothy writing experience. Pens also seem to write a bit drier on it, with slightly thinner lines. Machine 7 TRP has a more effortless glide, while Sanzen feels a little more controlled.
I have also seen user reports suggesting that Sanzen TRP may vary between batches, with some users reporting feathering or bleeding while others report excellent performance. I did not experience major issues with my sample, but it is something I would keep in mind when buying Sanzen TRP.
Overall, Sanzen TRP feels like the rightful successor to Machine 7 TRP. It may not fully recreate the exact writing feel of the original, but visually, it comes very close.
Sample C: Mark’s EDiT Notebook (Neo Agenda Paper)
Sample C is Mark’s Neo Agenda paper, used in Mark’s EDiT notebooks and planners. This was the paper that surprised me the most and originally prompted this comparison.
In my test, Neo Agenda paper performed very well with shading and shimmer. It was able to reproduce much of the depth and visual interest seen on Machine 7 TRP, especially with the shading inks. The shimmer inks also performed nicely, and the paper handled fountain pen ink better than I expected.
However, Neo Agenda was not able to fully replicate the sheen performance of Machine 7 TRP. In the Waterman Inspired Blue swatch, the red-purple metallic sheen that appeared clearly on Machine 7 TRP and Sanzen TRP was mostly absent.
In terms of writing feel, Neo Agenda and Sanzen TRP felt somewhat similar to me. Both have more texture and feedback compared with Machine 7 TRP, and both make pens write a little drier and thinner. They do not have the same effortless, glassy glide as the original Tomoe River Paper.
Still, Neo Agenda deserves more attention. It may not be a perfect Tomoe River Paper dupe, especially for sheen lovers, but it is a very capable thin notebook/planner paper. For people who enjoy shading and shimmer more than sheen, it could be a very interesting alternative.
Sample D: Iroful Paper
Sample D is Iroful Paper. I expected Iroful to perform strongly because it is often recommended as an ink-showcase paper. Surprisingly, in this comparison, it resembled Machine 7 TRP the least.
Like Neo Agenda, Iroful did not show much sheen with Waterman Inspired Blue. The red-purple metallic shine was mostly absent. More surprisingly, I also found the shading expression less dynamic. The shading inks did not appear as vibrant or dimensional as they did on Machine 7 TRP or Sanzen TRP.
For the two multi-chromatic shading inks, the different colours seemed to blend together more, presenting as a more uniform colour rather than showing distinct colour separation. With shimmer inks, Iroful appeared more absorbent in this test. The shimmer was still visible, but the base colour of the inks looked less saturated and more muted.
That said, Iroful has its own strengths. Among all four samples, it gave the smoothest and wettest writing experience. Pens felt very pleasant on it, and it had far less ghosting and bleeding because of its higher paper weight.
However, instead of resembling Tomoe River Paper, I found that Iroful performed more like Cosmo Air Light 75 gsm paper. It has a similar wet, slightly cushioned, sunken feeling when the nib touches the paper. It is a beautiful paper, but I would not personally describe it as the closest Machine 7 TRP replacement.
Final Ranking: Which Paper Is Closest to Machine 7 Tomoe River Paper?
1. Sanzen Tomoe River Paper
Sanzen TRP is my pick for the closest overall replacement. It reproduced Machine 7 TRP’s ink expression the best, especially for shading, shimmer, and sheen. It does not feel exactly the same when writing, but visually, it comes the closest.
2. Mark’s Neo Agenda Paper
Neo Agenda was the biggest surprise. It performed very well with shading and shimmer, and it deserves more attention outside Japan. Its main weakness is sheen. If sheen is important to you, it may not fully satisfy the Tomoe River craving. But as a thin planner/notebook paper with strong fountain pen performance, it is impressive.
3. Iroful Paper
Iroful is excellent paper, but I do not think it is a true Machine 7 TRP dupe. It is smoother, wetter, thicker, and much more resistant to ghosting, but its ink expression in this test was less similar to the original Tomoe River Paper. To me, it feels closer to Cosmo Air Light than to Machine 7 TRP.
Nakabayashi Yu-Sari Notebook also showcases ink colors really well. I did swatches with the same inks and kept it in this picture.
Conclusion
After comparing all four papers side by side, I would say Sanzen Tomoe River Paper is the closest replacement for Machine 7 Tomoe River Paper, especially if the priority is ink expression. It preserves the shading, shimmer, and sheen performance better than the other two alternatives.
Mark’s Neo Agenda paper was the most surprising candidate. It does not fully replicate Machine 7 TRP’s sheen, but it performs beautifully with shading and shimmer. For a paper that is much less discussed in the fountain pen community, it deserves more attention.
Iroful, on the other hand, is wonderful paper, but I do not think it should be treated as a direct Tomoe River substitute. It offers a smoother, wetter, thicker, and more cushioned writing experience with much less ghosting, but it does not recreate the same ink behaviour as Machine 7 TRP in my test.
So, is there a perfect Machine 7 Tomoe River Paper dupe?
Not exactly.
But if I had to choose the closest one, my answer would be Sanzen Tomoe River Paper.
If I wanted a surprisingly good thin notebook paper, I would choose Mark’s Neo Agenda.
And if I wanted a smooth, wet, lower-ghosting paper that makes writing feel luxurious, I would still happily use Iroful — just not as a Tomoe River replacement.
