Pilot Iroshizuku 100th Anniversary Inks, Part 2


Pilot celebrated their 100th anniversary with some vey expensive fountain pens and a set of 7 limited edition Iroshizuku inks. I decided to break the set up into 2 groups to review them. This time let’s take a look at Fukurokuju, Hoteison and Jurojin. You can find the 50ml bottles of these inks at Pen Chalet.



Hoteison is a dark green-black. Fukurokuju is a medium green and Jurojin is a cool, light purple.

Writing samples:

Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.


Dry time:

The inks took 30-40 seconds to dry.

Water resistance: Low

Feathering: Low-there was just a little bit of feathering in the flex nib on Rhodia and Leuchtturm.

Show through: Medium

Bleeding: Low

Other properties: All three had medium shading. Hoteison and Jurojin both had a tiny bit of sheen.

On Staples 24 lb copy paper there was lots of feathering in the larger nib sizes as well as a bit of bleeding.

Comparison Swabs:


Similar inks:

Hoteison is closest to Sailor Jentle Miruai. Fukurokuju is close to Robert Oster Opal Green. Jurojin is warmer than Ajisai, but not as warm as Robert Oster Summer Storm.


I used a Bond Travel Gear A5 notebook. I used a Pilot Vanishing Point Crossed Lines, a TWSBI Eco Transparent Green and a Pelikan M600 Violet, all with medium nibs. The inks all had a wetter flow.

Overall, out of the three I like Jurojin the most. It’s a pretty color, and I’m really enjoying it in the Pelikan M600 Violet right now.
