Yamamoto Canopus Paper Review

Yamamoto Canopus Paper Review

Us pen addicts are particular about our paper. It’s the engine that makes the pens and inks go, and it’s as important as any singular piece of the writing experience. So why does BIG PAPER keep taking away our favorites?

There’s books to be written about that one day, and I would like to nominate Taizo Yamamoto as the author. Taizo knows more about paper than anyone I know, and possibly more than anyone I don’t know. He is the person behind Yamamoto Paper, and his passion for paper knows no bounds.

His latest creation, Canopus, is designed to be a better version than one of the papers that got away in Cosmo Air Light. When I say creation, I mean that in a literal sense. Taizo creates some of his own paper formulas, and works with manufacturers to have them produced to his exacting specifications. His own Bank Paper was his previous creation, and now a new paper has entered the fray.

Yamamoto Canopus Paper

Colorverse Blue Crab ink in a Medium Jowo 14k Nib with a Stub Grind.

Canopus is designed to highlight the features of fountain pen inks. Colors are sharp, vibrant, and representative from the nib, and show off all of the different qualities inks have, such as sheen and shading. The feel of the paper is slightly soft and has a small amount of feedback, but is smooth overall.

Yamamoto Canopus Paper Ink

I used the smooth Kakimori Muddler for the top swatches, and the sometimes scratchier Kakimori Stainless Steel nib for the bottom.

Yamamoto Canopus Paper Sheen

A bit of a light angle change to see the shading, sheen, and shimmer of various inks.

Comparatively, Cosmo Air Light offered brilliant ink representation, but didn’t offer a great nib on the page experience. It had a soft feel, which caused line widths to expand. For example, a stock Fine Jowo Steel nib would leave a line width you would expect from a similar Medium nib. It also didn’t feel great from a tactile perspective. The page was spongy, and the finer the nib, the worse it felt in my experience. So I rarely, if ever, used it for that reason.

Yamamoto wanted a firmer page, and while Canopus is not designed to get all the way there like with Bank Paper or classic Tomoe River, it is clearly firmer than Cosmo Air Light. My most extreme nibs feel solid, with line widths on the page that I expected.

Various fountain pen nibs (left,) and standard pens and pencils.

Canopus is more of a writing page than Cosmo Air Light, but it’s not perfect. There are still some interesting “feels” with standard pens, which I use a lot of. For example, the Schmidt P8127 Rollerball felt grabby on the page, and a little odd. The color looked great, and there was no bleed or feathering at all, but it didn’t glide. Gel ink pens were better, ballpoint pens work on almost any surface, and the fineliner laid down nice lines. On some papers fineliners feel dry, but not here, so it might be a good drawing and sketching paper. Not for pencils though - they felt too glossy on the page.

Yamamoto Canopus Paper Back

Great performance overall, with no feathering or bleed. Even the Sharpie was better than on most papers.

Fountain pens were excellent across the board, even my super fine Pilot Posting nib and Sailor Extra Fine. There was no sinking into the page, and both were smooth. I will say, and this goes for any nib/ink combo on Canopus, you can’t double up your lines, or color over the same area a second or third time without the underlying paper beginning to come up. Obviously this is an issue with any water on paper, but I thought this broke down faster on the top of the page than other papers I use frequently (Life, Midori, Maruman, etc.). Interestingly, it rarely bled through the back side in those areas, which is nice.

Yamamoto Canopus Paper Shading

My kind of shading.

For me, Cosmo Air Light was never a product I wanted to use in a 200 page journal. Inks looked beautiful, but I didn’t enjoy writing on it. Canopus is better in that aspect, and I think I could use it as a journal paper, but still likely prefer it as a 50-80 page A5 note pad. These Bullet Paper Pads, which are what I’m using here, are narrower, but equally as nice. Plus, they are only $5.50 for 50 sheets, which gives you enough pages to test out and see if you want to take it further.

Since Canopus is new to the market, they are coming in and out of stock quickly at various retailers, but expect more after the San Francisco Pen Show, where Yamamoto Paper will be bring these, and more of their fantastic paper products.

(I bought this product from The Gentleman Stationer at regular price.)

Yamamoto Ro-Biki Shape Series Notebook Review

Yamamoto Ro-Biki Shape Series Notebook Review

(Jeff Abbott is a regular contributor at The Pen Addict. You can find more from Jeff online at Draft Evolution and Twitter.)

Always on the lookout for new pocket notebooks to try, I was keen to try out these the Shapes Series from Yamamoto Paper as soon as I saw them. I've had other notebooks from Yamamoto before, but not in this size. A little smaller than the common 3.5 x 5.5 pocket notebook size, I was curious to try out this slightly smaller version to see if I would notice the size difference.

The Ro-Biki Shape Series notebooks from Yamamoto Paper are small pocket-size notebooks that feature 60 pages of 80 gsm dotted ivory paper sandwiched between waxed paper covers with different designs.

Yamamoto Ro-Biki Notebook

The 3.5 x 5 inch (89 x 127mm) paper is the same size as the Passport size of Traveler's Notebooks, or the same size as a government-issued passport. This is a size that I'm sure many people are familiar with due to the popularity of the Traveler's Notebook system, but I haven't dabbled in this size before.

What really caught my eye were the cover designs. I went with Mountain Night and Wild Plants. There are many other unique cover designs that look great, but these two spoke to me. Getting them in hand, they look great in person and have a soft and pliable feel due to the wax coating treatment. According to Yamamoto Paper, the covers will patina in the same way as brass or leather as you use the notebooks. Aside from providing some protection from damage, the covers will also age and develop their own unique character with use. I'm looking forward to seeing how these covers develop their own story over the coming months of use.

Yamamoto Ro-Biki Notebook Writing

The paper used in these notebooks is fantastic. It's 80 gsm paper that is 100% made from recycled paper with an ivory hue and light gray dots. Writing on the paper is a smooth experience, and I've really enjoyed it with any kind of writing instrument I've tried. I haven't seen any feathering or bleeding, which is great, and the paper works well with all kinds of ink and graphite. There is some minor show-through on the back side of the page, but it's not so bad that it makes the back side unusable. You can definitely see some ghosting, but it's easy to ignore when writing on the back side of the page. For a pocket notebook, I'm fine with sacrificing some paper thickness for lighter weight and thinner notebooks.

The notebooks are bound with both glue and stitching, and feel really solid in use. I have no doubts that these notebooks will hold up well, especially compared to the typical staple binding that a lot of pocket notebooks use.

Yamamoto Ro-Biki Notebook Cover

The inside of the notebooks are completely empty. There's no marketing on the inside covers. The only branding is the small Yamamoto Paper logo on the back cover.

While the passport size notebooks look a lot smaller than the 3.5 x 5.5 inch notebooks I'm accustomed to, it's just an optical illusion. For my use, that half inch height difference isn't noticeable when writing, but it is noticeable when it comes to stashing the notebook in pockets or sleeves. After using these notebooks for a little while, I think I'm already starting to favor this passport size over the slightly larger 3.5 x 5.5 inch size.

Yamamoto Ro-Biki Notebook Binding

At $8 per notebook, these notebooks are a little pricey. A more typical price for a pocket notebook is around $5. The waxed cover and nice paper definitely add a premium feel, but it still seems a little high. At the end of the day, I'd still choose to buy these notebooks again just because I really enjoy the cover designs and how the cover feels in hand. As with all things in this hobby, your mileage will vary, and your opinions are valid! If these little notebooks are calling out to you, you won't be disappointed once you have them in hand. They're high quality products that are a joy to use. Be sure to check out the other cover options!

If you are a fountain pen and ink user you have certainly seen the various collections that Yamamoto Paper put together for users to test out a wide variety of paper before committing to a full notebook of the good stuff (here is an earlier review from Susan if you aren’t familiar.)

Taizo, the owner of Yamamoto Paper, handed me this pad at Stationery Fest, and while they haven’t hit the market yet, they should be coming soon. (Keep an eye on Vanness Pens Yamamoto Paper page!)

This pad contains 10 sheets of 5 different fountain pen friendly papers:

This is a great playground for pen and ink users, and I have one of these pads to give away this week. Read the rules below and enter away!
