Hydrangea Pilot Iroshizuku Bottled Ink(50ml) Fountain Pen Ink

Yu-Yake, meaning “sunset” in Japanese, is a perfect name for this vibrant ink from Pilot’s Iroshizuku line. It’s a warm, golden orange that somehow manages to feel both bold and gentle—like the last glow of sunlight before dusk settles in. I tested it in my Monteverde MP1 OmniFlex fountain pen, and the experience was nice and smooth. The ink flows easily and consistently, which really brought out the flex nib’s expressive qualities. I got some beautiful natural line variation, and even a bit of subtle shading—especially on higher-quality paper like Tomoe River. The color itself is rich and lively without being overly bright. It's not a neon or fire-orange—it’s deeper, almost like roasted pumpkin or a glowing ember. It makes a statement, but it’s not aggressive. I’ve used it for journaling, art journaling accents, and even personal notes. It adds warmth and personality without compromising readability. Dry time was quick—around 10 seconds on most papers I tested. No feathering, no bleed-through, and just a hint of ghosting on very thin paper. It’s well-behaved, as you’d expect from Iroshizuku. The bottle is also worth mentioning—beautifully designed, easy to fill from, and it feels like a luxury item in the best way. Pilot really nailed the entire experience, from color to packaging. Final thoughts: If you’re looking for an orange ink that captures the beauty of a fading sunset—something warm, expressive, and surprisingly versatile—Yu-Yake is a must-try. It’s a color that feels good to write with. I always find myself reaching for it when I want to feel a little more present, grounded, and creative.

Love the entire range of these fantastic inks. Highly recommended!

Love this colour and will keep it as regular ink for my pens.

It’s such a beautiful color

Pilot makes quality ink. It flows so smoothly from my pens. Kon-peki is a beautiful color. This makes my second Pilot Iroshizuku ink. I also own Asa-Gao.

A pleasing blue ink for less formal letters.

Having used a sample of this ink before, I decided to get this bottle since I like the ink so much.

I use several of these inks for writing letters. When I write my daughters I like soft colors. Outstanding price to value for a truly premium ink.

One of my favorite reds.

Just the brown (Tsukushi) i was looking for, it's a great medium brown w/a hint of red & subtle green/gold sheen. Flows really well in EF & M used in so far, too bad it's a discontinued ink, but i'm sure i'll find a good replacement if i ever finish this bottle. God bless (Matthew 5:45)!
