The Buzz from Beautyworld Japan: Why Top Lash Artists Are Raving About "NUMERO KURO"
If you’ve been keeping an eye on the Asian beauty market, you know that Beautyworld Japan (BWJ) Tokyo is where the biggest trends and product innovations are born. At the recent BWJ Tokyo exhibition, one of the biggest showstoppers at the Matsukaze booth was the official launch and showcase of NUMERO KURO—the evolution of our bestselling flat lashes.
Today, we’re sharing the real feedback from top Japanese lash artists who visited our booth, and why this innovative "Deep Black" flat lash is set to become a global standard for premium lash salons.
The Secret Demand: Why Eyelash Extensions Are Surging Among Gen Z and Millennials
While lash lifts (lash perm) have seen a global rise in popularity, the demand for eyelash extensions remains incredibly strong, especially among younger demographics.
According to recent data from Japan’s leading beauty booking platform (Hot Pepper Beauty), "Eyelash Extensions" ranked as the #2 most-searched keyword for teens and #5 for twenty-somethings.
For salon owners, extension menus remain the core driver for customer retention and increasing average spending per guest. However, to stay competitive, lash artists need two things: effortless application (smooth salon work) and the ability to create striking, customized designs that leave clients in awe. That is exactly why NUMERO KURO was born.
From "Matte Black" to "KURO": The Quest for the Perfect Deep Black
While our previous "NUMERO Matte Black" was already a favorite among professionals, we didn't stop there. We listened closely to lash artists who struggle with common flat lash issues:
-
The "Plastic Glare": Some black lashes have a blueish tint or artificial glare under bright light, making them look unnatural against real lashes.
-
Tapered Volume Loss: Lashes that taper too early or too finely at the tips often lose their density, failing to give that sharp, eyeliner effect.
NUMERO KURO (meaning "Black" in Japanese) completely solves these pain points. We meticulously upgraded the color pigment, the tip sharpness, and the uniformity of the lash thickness to create a flat lash that offers both high density and a soft, natural texture.

The response at BWJ Tokyo was overwhelming. Here is a breakdown of the real feedback from professional lash artists who experienced NUMERO KURO firsthand:
