Hello, this is Kaori from HIDARI.
With only a few months left in the year, it’s the perfect time to start preparing for next year—and that includes picking out your planner! The HIDARI Left-handed Planner 2026(Japan Edition), which went on sale in September 2025, is now showing the ranking of its most popular colors so far.
🥉 3rd Place (Two Colors Tied!)
First is the brand-new Lavender.
Purple shades have always been popular at HIDARI, with Violet in 2025. This year’s Lavender stands out with a vivid yet refined look, offering a different kind of elegance.
Tied for 3rd is Ivory.
A revival color from the 2021 edition, this warm off-white is soft and approachable. Its PVC cover makes it easy to wipe clean, and the light color gives a fresh impression—one that I personally find very appealing.
🥈 2nd Place – Peacock Blue
Originally released in 2023 as an online-exclusive, this vibrant blue-green has returned to great acclaim.
It was just a hair’s breadth behind the 1st place, and the rankings could still change in the coming months!
🥇 1st Place – Mango
This year’s new color, Mango, is bright, cheerful, and full of energy.
Unlike Neon Orange (2024) or Yellow (2025), Mango has a juicy, warm tone. It’s also easy to spot in your bag or on your desk, making it both fun and practical.

At HIDARI, we want to change the common experience many left-handers know too well:
"If there’s a left-handed option at all, it usually comes in only one color."
That’s why we offer as many color variations as possible.
We hope you’ll find your favorite color and enjoy 2026 with your HIDARI Left-handed Planner!
