What happened to Tomoe River Paper?

(Update – May 2023)

So much has happened since I put pen to the “Old” Tomoe River paper back in October of 2020 (in the world and with the paper,) that we thought it might be time for an update.

At the time, I was blissfully unaware of what was happening a world away in Japan at Tomoegawa, where machine #7 was about to cease production of Tomoe River paper. It would soon be moved to Shizuoka machine #9, where “New” Tomoe River paper would be made until the end of October 2021. Rumblings in the pen world became louder and louder and the hoarding of the “old” paper commenced. This was followed quickly by the purchasing of large quantities of the “new” TR when it was announced that Tomoegawa would stop production of Tomoe River paper altogether. I will admit that even I caved and wrote a frantic email to Yunus at Galen to set aside two sets of my favorite B5 Everyday Books.

Thankfully, the Sanzen Paper company came to rescue, purchasing not only the remaining inventory of the “New” Tomoe River paper, but also the rights to Tomoe River. Sanzen is part of Japan’s largest paper manufacturing conglomerate, so the future of Tomoe River seemed to be in capable hands for the long run and a sigh was heard in the stationery and pen communities.

As Sanzen was in the midst of the purchase, they were already producing their version of Tomoe River. In fact, their Tomoe River paper is already out in the marketplace. Skeptics and “Old” TR lovers had to assume it would be inferior to the original. Aren’t the new kids on the block almost always?

But this TR diehard might just be a convert. The Sanzen paper is different, but not at all unrecognizable. In fact, it’s just a touch more textured and that seems to be the only discernable difference that I can notice. If I’m being honest, I might even like it a tiny bit more, especially for some of my smoother pens and wetter inks.

Hopefully, the drama of TR has simmered down for the time being or even for good, but should there be more news to report, I’ll meet you back here.

In the meantime, have you tried all three versions of Tomoe River? Do you have a favorite and why? Let us know in the comments. We love hearing what you think!

Tomoe River Paper

The blank page has plagued writers since there have been writers. Even now, as I type this, I am staring at a blank page, albeit on a laptop, rather than my preferred type of blank pages in a notebook or a stack of loose-leaf sheets. As terrifying as the blank page can be, it can also be an invitation to express thoughts and possibilities, ideas and inspiration. As I have become more and more enamored with the art of the analog, I have found myself in search of the perfect paper for a blank leather journal, and for me the answer to that search is Tomoe River paper.

First Impressions

I first experienced this paper in a Hobonichi planner, marveling at the thin paper that withstood a year’s worth of to do lists, plotting and planning. A pencil and rollerball lover first, midway through my first Hobonichi I purchased a fountain pen and as I fell down the rabbit hole of fountain pen collection, I realized that every medium I tried on the Tomoe River paper seemed to offer similar results; magically, I could not see the previous day’s writing and drawings on the next page. Like any good stationery addict, even though I had encountered a paper that worked for me, I still needed to try all of the others. So I’ll use this entry to the blog as a way to share with you some of what I’ve learned about Tomoe River Paper historically and practically.

The History of Tomoe River Paper

In 1914, Tomoegawa Paper Company was founded in Shimizu City, Shizuoka Prefecture, Japan. The company was named for the Tomoegawa River that flowed near the manufacturing site. 105 years later Tomoe River, the paper originally made for catalog mailings, is one of the modern stationery aficionado’s most beloved papers.

Tomoegawa is a very big corporation, with very professional staff and high quality standards. They do not sell direct to any downstream companies that make end-user stationery products. Sakae Technical Paper is the sub company own by Tomoegawa, and distrubiting the Tomoe River paper.

What Makes Tomoe River Paper So Special?

tomoe river paper coatingSpecially coated on both sides, so ghosting is minimal.

Using pulp made from trees in sustainable forests, the paper is remarkable for many reasons, the first being its thinness. Whether the 52gsm or 68gsm, even hundreds of sheets stitched into notebooks have a very low profile, making them lighter than notebooks with similar page counts. The acronym “gsm” stands for grams per square meter, the higher the number, the heavier the paper. With just a slight increase in gsm, the 68gsm Tomoe River paper is still quite thin. When using the 68gsm version, the user may notice some slight differences in texture and some other distinctions that I will relay later in this article when we discuss the attributes of the paper.

Because Tomoe River paper was originally developed for catalogue mailings, it has enough density and sizing to be resilient to multiple uses. It can be hole-punched for binders, put through a jet printer, folded to make different paper sizes, be written and even painted on.

Tomoegawa manufactures Tomoe River paper in both cream and white for those that have a preference between bright white or a softer cream color when writing.

Tomoegawa, the company that manufactures Tomoe River, makes two kinds of 52 gsm paper. One kind is for offset printing, and comes in many colors. That’s not the paper we use. We use the “stationery” paper, which comes only in cream and white, and is specially formulated for handwriting, as opposed to printing press paper.

How To Use Tomoe River Paper

tomoe river paper feathering testTomoeRiver FP” paper is designed especially for fountain pen users and is the highest quality paper among all TomoeRiver papers and other top papers out there.

Tomoe River Paper is extremely smooth, making it useful for many mediums: pencil, rollerball, gel pen, fountain pen and even light washes of watercolor. While the paper has a capacity for absorbing, some may find that it takes longer to dry depending on the medium they are using. While it can be a very enjoyable surface for wet mediums like fountain pen ink and watercolor paint, it is not generally suggested for alcohol-based paints, markers and inks. When in doubt, it may make sense to have a tester sheet to try mediums that you are worried may perform poorly on the paper.

It’s helpful to know how fountain pen ink and watercolor behave on Tomoe River paper. Fountain pen enthusiasts who favor shading ink, those that create subtle color gradations as ink is laid on the paper, will appreciate how the paper shows off subtle color variations. Sheening inks also perform well as pools of color will sit on the surface of the paper and when dry will create the reflective look so many fountain pen users love. It’s important to be patient and let the paper fully dry to prevent smudging, especially when using sheening or metallic inks.

When using watercolor be prepared for the paper to pucker slightly. Once dry, the paper will relax some, but it will have some remaining crinkle. Some love this new texture, some don’t. You just have to figure out which side you fall on.

The Difference Between 52gsm and 68gsm Papers

I promised to share some differences between the 52gsm and 68gsm. With regards to sheen, the lighter 52gsm paper tends to show off sheen better, meaning color variation and reflection may be more obvious on this weight. 68gsm tends to show bleed through less, especially with wetter mediums and it is more resistant to ghosting, which for many writers is the thing they most dislike about taking paper to pen. Ghosting is the shadow that one sees when using both sides of the paper. With 68gsm, there is less ghosting, though still some, with 52gsm showing more through pages that have been written and drawn on. While bleed through can be a concern, feathering generally isn’t.

How Does Tomoe River Paper Compare To Others?

Compared to other papers, Tomoe River is distinguished for all of the reasons above. Compared to Rhodia and Clairfontaine papers, Tomoe River has been found to have a longer dry time. Compared to Apica, the results are fairly similar, though the Apica is a thicker paper. CD professional has been noted to be slicker and glossier and less effective with shading inks, MD paper and MD Cotton more absorbent. As with most things paper related, much of the decision to use one paper over the other is a personal preference.
