Iroshizuku by Pilot is truly a household name in the fountain pen world, and I believe almost every enthusiast is familiar with these inks. I tried my very first Iroshizuku — Ajisai — a long time ago, and my initial experience was actually negative because it feathered heavily on the page. At that time, I didn’t know much about fountain pens; I was using poor-quality paper and a broad nib, among other factors.
The second time I tried it was when I encountered a baby-bottom issue on one of my pens, and someone recommended using a wetter ink. It worked perfectly — and from that moment forward, Pilot Iroshizuku inks became a regular part of my lineup.
Today, I’m a proud owner of all 24 standard Iroshizuku colors. But in reality… there are 34, or perhaps even more? I’ll also show you the limited editions released for the 100th anniversary…

Pilot Iroshizuku inks are regarded as some of the finest fountain pen inks in the world. Their formula is known for:
- More watery consistency — excellent flow, ideal for drier nibs
- Smooth writing with consistent lubrication
- Elegant shading that adds character to handwriting
- Nature-inspired color palette with poetic Japanese themes
- Good performance on quality paper
- Easy cleaning thanks to their gentle water-based formulation
Advantages & Disadvantages of Pilot Iroshizuku Inks
Pilot Iroshizuku inks have earned their reputation as some of the most refined and enjoyable fountain pen inks available today. Their formula is noticeably smoother and slightly more fluid than many others on the market, giving them excellent flow even in drier nibs. This creates a pleasantly lubricated writing experience, where the pen glides effortlessly across the page. The inks also deliver beautiful shading and expressive color variation, bringing life and depth to handwriting without requiring any specialized nibs.
The Iroshizuku palette is inspired by the beauty of Japanese nature — snow, forests, rivers, dusk skies, blooming flowers — and each color carries a poetic story. Thanks to this thoughtful design, users can choose inks not only by shade but also by mood and personal expression. Practical benefits accompany this artistic quality: Iroshizuku inks are water-based and well-behaved, easy to flush out of pens, gentle on feeds and converters, and unlikely to cause clogging or staining. The glass bottle design is also iconic — elegant, functional, and collectible.
There are a few characteristics to keep in mind, though none diminish the overall value of the line. Because the inks are more watery in consistency, they may feather or bleed on poor-quality paper — though they perform beautifully on fountain-pen-friendly paper. They are also not formulated for strong water resistance, making them better suited for journaling, notes, and expressive writing rather than archival or official permanent documents. Finally, the premium presentation and performance come at a higher price point compared to standard inks — yet most users agree that the quality and experience justify the cost.
Overall, Pilot Iroshizuku inks strike a rare balance between beauty, reliability, and emotional expression. They enhance not only how writing looks, but how writing feels. For anyone who appreciates smooth performance, poetic colors, and thoughtful craftsmanship, Iroshizuku remains one of the finest and most rewarding ink collections to explore.
Why I Love Pilot Iroshizuku Inks
Pilot Iroshizuku inks have become some of my all-time favorites, not only for their stunning Japanese nature–inspired colors, but also for their performance. The shades aren’t just “blue” or “green” — each one feels like a story on the page, carrying emotion, atmosphere, and culture with every stroke.
What I appreciate most is the writing experience: the inks flow beautifully, feel smooth on the nib, shade elegantly even with simple handwriting, and are easy to clean from any pen. Paired with good paper, they deliver crisp, refined lines that elevate everyday writing.
Owning the full main lineup has shown me how diverse and expressive these inks can be. Every time I fill a pen, it feels like a small creative moment — a perfect blend of practicality and artistry that always inspires me to write more.

Tokyo 2007 Limited Edition – A Collectible Tribute from Iroshizuku
At the end of 2007, the premium ink line Pilot Iroshizuku released a special Tokyo-themed limited edition series — available only in Japan. The set was conceived as a homage to historic neighborhoods and traditional districts of Tokyo, capturing the spirit of the city’s old charm and urban heritage through ink. Because the bottles were sold exclusively via select Japanese retailers and were never mass-distributed internationally, these inks quickly became rare collector’s items.
Ink Profiles
Fukagawa-Nezu — Misty Grey Elegance
• Meaning & Inspiration: Named after the historic district of Fukagawa in Tokyo — invoking images of quiet backstreets, stone bridges, and evening mist.
• Color & Behavior: A cool, smoky grey with a slightly soft tone. It’s not a flat grey — shading brings subtle depth, giving writing a misty, atmospheric mood. Works well for notes, sketches, or journal entries where you want elegance without bold colors.
• Why It Matters: As a subtle, nuanced grey — somewhat rare among fountain-pen inks — it stood out for those seeking understated sophistication.
Shimbashi-iro — Urban Vintage Blue-Black
• Meaning & Inspiration: Shimbashi is another historical area of Tokyo, known for its old-town energy and early railway era charm. The ink was meant to capture that urban, slightly nostalgic atmosphere.
• Color & Behavior: A deep blue-black tone with enough richness to work as a reliable writing ink, yet with a softness that distinguishes it from harsh blacks. The ink carries a sense of quiet authority and classic style — ideal for formal letters, journaling, or creative writing where character matters.
• Why It Matters: The balance between usability (as an everyday ink) and subtle distinctiveness made Shimbashi-iro a top choice for those valuing function and personality.
Edo-murasaki — Historic Purple Nobility
• Meaning & Inspiration: “Edo” refers to old Tokyo, before it was renamed, and “murasaki” means purple — a color traditionally associated with nobility and elegance. Thus Edo-murasaki was a tribute to the old heritage and cultured spirit of the city.
• Color & Behavior: A deep, dignified purple — rich but not overly saturated, offering elegance and a touch of authority. Great for expressive writing, poetry, signatures, or creative projects that call for a distinguished ink hue.
• Why It Matters: As a purple ink with such a meaningful backstory, Edo-murasaki appealed to those who love history, nuance, and individuality in their writing tools.
