A monthly and weekly planner for left-handed writing.
16 months of dated pages, from December 2026 through March 2028. Made in Japan in a compact B6 format, with weeks starting on Monday.
Why we made this
We designed the HIDARI planner to make dates and weekly plans easier to see while writing with the left hand. We’ve refined it with feedback from users since 2019.
Lies flat, without rings
Thread-sewn binding opens flat at 180°, so you can write close to the spine without a ring pressing against your hand.
Dates where you can see them
The date numbers sit in the upper right, making them easier to check as you write with your left hand.

Your week on the right. Your notes on the left.
Your weekly schedule is on the right-hand page, with a full notes page on the left. You can refer to your plans while making lists or writing reminders.

Layout example. The 2027 edition runs from December 2026 to March 2028.
Bound on the right
The spine is on the right, so you can move forward through the planner with your left thumb.
Paper and cover
Thin, smooth Seibundo planner paper provides an even surface for writing. The water-resistant PVC cover wipes clean and has a gold-foil title. Choose from Navy, Beige, Mint Green, Yellow and Red.
