Pilot’s Iroshizuku ink line regularly makes an appearance on my list of ink recommendations, particularly as a great workhorse ink that behaves well in all pens and on most paper. Unfortunately, while once admired for its gorgeous glass inkwell-style bottle and expansive color range, it seems as though Iroshizuku has been drowned out by the ever-increasing number of boutique ink brands with dozens of colors in their lineup. Why do I keep coming back to Pilot? For one thing, sometimes too much choice can feel paralyzing, and the Iroshizuku line of inks is just big enough to offer a comprehensive selection of colors without having to worry about whether the inks are “safe” for fountain pens or will offer inconsistent performance. While I’ve found certain Iroshizuku colors to be a touch light, and some to feather more than others on cheap recycled paper, PIlot makes consistently good inks across the board and I’d love to help refocus attention on what should be a staple in most ink collections, especially those focused on everyday use.

A year or so ago, I began picking up bottles of Iroshizuku, hoping to collect most of the line so that I could offer a comprehensive overview - a bit of an overwhelming project that didn’t get off the ground until now. I ultimately decided to break this review up into a series of posts, since I can’t reasonably ink up and use all the Iroshizuku inks at once. Today I start with three well-known favorites.

Pilot Iroshizuku Yama-Budo

Yama-Budo, a dark pink-purple sometimes translated as “crimson glory vine,” has remained a favorite ink, though lately I don’t use it as much as I’d like. (That will change.) For me, it’s easily the most usable color on the “pink” spectrum, and over the years it’s made frequent appearances at the office. Yama-Budo has also been one of the better behaved inks in the entire Iroshizuku lineup, and I’ve not had serious issues using it on inexpensive copy or office paper. This ink has a touch of shading and reddish/gold sheen on certain papers.

Pilot Iroshizuku Shin-Ryoku

I haven’t used Shin-Ryoku (“forest green”) much at all, even though it’s one of the more standard “work friendly” colors in the Iroshizuku line. A mid-toned green, Shin-Ryoku starts out with a bit of a blue tone when wet (think Waterman or Pelikan greens) but darkens as it dries. Though perhaps not the most exciting color, sometimes that’s exactly what you need whenever you just want to get some work done. This ink can also have a bit of shading and show some reddish sheen on certain papers.

Pilot Iroshizuku Kon-Peki

I remained a bit contrarian on Kon-Peki (“deep cerulean blue”) for years, before ultimately accepting that it’s a great blue ink with a lot of pop. Though Asa-gao (full review forthcoming) is probably my favorite Iroshizuku blue, Kon-Peki is unique in its vibrancy and presents a safer alternative to some of the “cult favorite” bright blue inks from boutique brands, which can cause clogging and smearing due to their oversaturation with dye.

Takeaways and Where to Buy

I think I’m going to enjoy working my way back through the Iroshizuku lineup. The inks are great and it’s always a pleasure to have a beautiful glass bottle on your desk. I’ll add that the Iroshizuku bottle is as practical as it is pretty, with a wide opening that allows you to fill larger pens, and a depression at the bottom that makes it easier to fill as the ink level in the bottle gets lower.

As of 2023, The T.G.S. Curated Ship is able to offer you Pilot pens and inks directly, including the entire Iroshizuku lineup. We currently carry the 50ml bottles of ink, priced at $24.

I’ve written about several Iroshizuku inks in the past - including two of the inks featured above - but it’s been years and I intend to revisit them all as I work my way back through the line as part of this current project. If you’d like, check out my previous reviews of Tsuki-Yo, Yama-Budo, Kon-Peki, Asa-Gao, and Yu-Yake.

Whoa. As of last night I thought today might be the day that I missed my blogging schedule for the first time since this blog has been live. Due to a series of cascading airline delays, I staggered in at 1 a.m. last night after nearly 12 straight hours in Boston Logan Airport. (I did get a chance to visit the famed Bromfield Pen Shop, albeit briefly, though my schedule and DC Pen Show induced discipline prevented me from buying anything). So today, I offer you an ink review that I've had in the can for a while but haven't posted simply because I think this ink has been reviewed to death and I've never been quite able to make myself love it.

Everyone's favorite Iroshizuku--except mine.

Honestly, though, I know why other people love this ink, and it's for the same reasons that I haven't sold the bottle. It's got a Baystate Blue-style pop to it with none of the headache. Like all Iroshizuku inks, Kon-Peki is well behaved and cleans out of pens easily. But I'm not a blue ink kind of guy. I mean, I like blue ink, and sometimes I have to use it for work, but I'd rather use a blue-black or a turquoise. If I do have to use a blue ink, more often than not it's this one, which people term "cerulean." This review was written with an Omas Ogiva ground by Mike Masuyama to a Japanese medium. (I asked him to copy the nib width on my Nakaya portable writer, which is perfect for me).
