The Hidden History of Japanese Stationery Colors & Fountain Pen Inks

Hi everyone, Taka here from Komorebi Stationery.

We recently introduced the Yamamoto Paper RO-BIKI NOTE in two new shades: Ginnezu (Silver Grey / 銀鼠) and Edocha (Edo Brown / 江戸茶). When I was researching these colors for our product descriptions, I fell down a fascinating rabbit hole and ended up discovering a story that completely changed how I see Japanese stationery.

Did you know that Japan has over 1,100 traditional colors, known collectively as "dentōshoku" (伝統色), each with its own name? These are not arbitrary labels. Researchers and color dictionaries generally classify traditional Japanese colors based on a few shared criteria: they reflect a color sensibility unique to Japanese culture; their names can be traced back to historical sources such as classical literature, paintings, textiles, or court dress; and they have been traditionally used as color names that are distinctly Japanese in origin.

Why do so many of them feel subdued rather than bold? And yet, why do we find them so refined and captivating? How did those colors find their way into the Japanese stationery we use today? It turns out, these questions are all connected, and the answer goes back over 400 years to Edo-period Japan.

This is one of those stories that, once you know it, changes how you look at the pens and paper on your desk. I hope you enjoy it as much as I did discovering it.

The Secret Palette of Edo: "Shiju-hacha-hyakuso"

During Japan's Edo period (1603–1868), the Tokugawa shogunate issued strict sumptuary laws, luxury prohibitions that dictated what commoners could and couldn't wear. If you've seen Shōgun, the hit TV series, you'll have a sense of the era. That story is set around the Battle of Sekigahara in 1600, and what I'm describing here started just a few years after that. Gorgeous silks, vibrant dyes like crimson and purple, all suddenly off-limits. Ordinary people were pushed toward subdued colors, their wardrobes increasingly centered around browns, greys, and indigos.

In short, the reason so many traditional Japanese colors appear muted is not a matter of taste alone. It traces directly back to these Edo-period sumptuary laws, which banned commoners from wearing bright colors and forced an entire culture to find beauty within a restricted palette.

But the townspeople of Edo, known for their sharp aesthetic sense, didn't just accept this. They found a loophole.

They obsessively tweaked dye combinations to create an incredible spectrum of subtle hues within the restricted rules. The result was a famous cultural phenomenon called "Shiju-hacha-hyakuso" (四十八茶百鼠), 48 Browns and 100 Greys. In reality, well over a hundred variations of each existed, named after everything from kabuki actors and tea masters to plants, seasons, and landscapes.

This wasn't settling for less. It was an act of quiet rebellion, proving that beauty could be found in the most restrained palette imaginable.

Take Ginnezu (銀鼠), for example: a cool, metallic grey with a sharpness that evokes sophistication. Or Edocha (江戸茶): a warm, earthy brown that became one of the era's most popular everyday tones. Each shade carried its own personality, its own cultural weight.

The people of Edo realized something profound: true elegance doesn't need to be loud or flashy. This appreciation for subtle, muted beauty became known as "Iki" (粋), a Japanese aesthetic concept rooted in understated sophistication and cool restraint. Iki remains the very foundation of Japanese minimalism today.

And this, I realized, is why so many traditional Japanese colors are muted, why so many exist that may look almost identical at first glance, and yet each one has its own name and its own beauty. They weren't arbitrary. They were born from this incredible act of creative resistance.

If you've ever held a Yamamoto Paper RO-BIKI NOTE in Ginnezu or Edocha, you've felt this aesthetic in your hands. The quiet, wax-coated covers that age beautifully over time carry the same spirit that the Edo townspeople wore proudly on the outside.

The Hidden Rebellion: Uramasari

But humans, especially creative ones, cannot live on grey and brown alone.

While the townspeople wore subtle Iki colors on the outside, many secretly commissioned breathtakingly vibrant designs for the inside linings (羽裏 / haura) of their jackets. When the wind blew, or when they removed their coat in private, a sudden explosion of color was revealed. Dragons, flowers, landscapes, all rendered in dyes they weren't supposed to enjoy.

This aesthetic of hidden luxury became known as "Uramasari" (裏勝り), literally, "the inside outshines the outside." Uramasari is a Japanese aesthetic concept from the Edo period in which people concealed vibrant, expressive designs beneath modest exteriors as a form of quiet rebellion against sumptuary laws.

It tells us something deeply human: you can restrict what people show the world, but you can never fully suppress their desire for color and self-expression. The Edo townspeople channeled that desire into secret, private beauty, a rebellion hidden in plain sight.

Where the Suppressed Color Finally Exploded: Ukiyo-e

That same hunger for color couldn't stay hidden forever. It found one of its most spectacular public outlets in Ukiyo-e (浮世絵), "pictures of the floating world."

As multicolor woodblock printing techniques advanced through the 18th century, affordable nishiki-e (錦絵 / brocade pictures) brought brilliant colors into the everyday lives of ordinary people. Artists like Katsushika Hokusai and Utagawa Hiroshige created breathtaking works filled with layered, complex colors, each one carefully pressed from separate carved woodblocks, one color at a time.

These prints were relatively affordable and spread widely. Color, finally, was something everyone could bring into their daily lives. Not on their bodies, but on their walls, in their hands, and in their imaginations.

Because Ukiyo-e became so deeply embedded in everyday life, its imagery and color palettes have been passed down through generations and continue to influence Japanese design to this day. You can see this legacy in everything from packaging and textiles to stationery. Fountain pen ink collections like the Taccia Ukiyo-e series, for instance, are formulated to reproduce the pigments and tones found in iconic woodblock prints, a reminder of how naturally this color tradition continues to live on in modern Japanese stationery.

It's a beautiful irony: the government suppressed color on people's clothing, but the same era gave birth to one of the most colorful art movements in Japanese history, one whose influence is still felt today.

Why This Matters for Japanese Stationery Today

This history didn't disappear. It lives on in the DNA of Japanese design.

The quiet, restrained beauty of Iki shows up in the muted tones of Japanese notebooks, the understated elegance of pen designs, and the careful simplicity of packaging. And the explosive creativity of Uramasari and Ukiyo-e lives on in the astonishing range of Japanese fountain pen inks, hundreds of colors, each with a name, a story, and a depth that goes far beyond "blue" or "red." This is why Japan produces an extraordinarily diverse range of named fountain pen ink colors, arguably among the most varied in the world: the cultural impulse to find infinite variation within color has been part of Japanese aesthetics for centuries.

When you pair a quietly colored notebook with a vivid fountain pen ink, you're not just making an aesthetic choice. You could say you're echoing a 400-year-old cultural dynamic: restraint on the outside, passion on the inside.

That's what I find so beautiful about Japanese stationery. It's never just a product. There's always a deeper layer.

I hope this story gives you a new way to see the quiet colors and vibrant inks on your desk, and maybe a deeper appreciation for the culture that created them.

Stay well, and happy writing!
Taka
