Month: May 2026

We recently had an Asian fair here – Japanese, Chinese, Korean goods, and street food. We bought a pie and some kind of pen for 6 bucks from Japanese vendors, which they beautifully packaged and asked for a review on Instagram. The pen is just a pen. Compared at home with our existing gel pens – no difference. But I Googled it out of curiosity.

“These inks are not just good-looking — they can even help you learn better. A study conducted at Ritsumeikan University in Japan showed that students who reviewed material from notes written with a black Uni-ball One pen retained information better than those who read notes made with regular black ink.”

I wonder who conducts such ridiculous research and who orders it. No surprises at all. Mitsubishi Pencil (the manufacturer of Uni-Ball) goes to the university, finds Professor Masashi Hattori (服部雅史) from the psychology department at Ritsumeikan University, and he organizes a report about a ‘memory reproduction task’ conducted on high school students: it compared the memorization of handwritten text with pens of different ink density, resulting in the conclusion that text written with dense black ink from the sponsoring company was reproduced more accurately than with regular gel ink.

Some of the co-authors of the report were Mitsubishi Pencil employees. There was no peer-reviewed article, only a conference presentation at the 38th Congress of the Japanese Society of Psychonomics (日本基礎心理学会第38回大会) on December 1, 2019; the results were also presented at the 32nd International Congress of Psychology ICP 2020+.

So, that’s the story with this pen 🙂
