手帳特色

A planner made for the left hand.

Dates in the upper right. Notes on the left. Pages that open from left to right.
Small details, reconsidered for the way your left hand moves.
Designed in Gifu. Made in Japan.

Small changes make a planner feel completely different.

Most planners quietly assume a right hand.

The date can disappear beneath your writing hand. Your arm can cover your schedule while you write on the notes page. Even turning to the next page can feel slightly backward.

None of these things is a big problem on its own. But a planner is something you use every day.
So we reconsidered the layout from the left hand up.

Made to be used, every day.

A left-handed layout only matters if the planner itself feels good to use.

Three details designed for the left hand.

解放你的左手。解放你的思想釋放左手，釋放思緒。

HIDARI 的左手專用手帳不是單純將一般手帳左右翻轉，而是從左手使用者的書寫動作與翻頁方式出發重新設計。長久以來，左手使用者總得適應以右手為前提的工具；現在，讓工具來配合您。

02. Schedule on the right. Notes on the left.

The weekly schedule sits on the right-hand page, with a full notes page on the left.
You can write notes with your left hand while keeping your plans in view.

無線圈、可 180° 攤平的裝訂

採用線裝工法，攤開時可平整展開。沒有金屬線圈或凸起妨礙手部，書寫範圍更加順暢。

Details that make it good to use.

Lies flat at 180°

Thread-sewn binding lets every spread open completely flat, without rings or bulky hardware getting in the way.

Smooth planner paper

Thin, smooth and durable Seibundo planner paper gives your pen a comfortable surface to move across.

Tear-off memo pages.

Perforated memo pages make it easy to take a note with you when you need it.

Two ribbon bookmarks.

Two ribbons help you keep your place in the sections you use most.

Refined with left-handed users since 2019.

HIDARI's planner has been refined year after year by listening to the people who actually use it.

HIDARI itself began from Aya's experience as a left-hander looking for tools she genuinely wanted to use — not novelty products, just good tools that happened to fit her left hand.

That idea still guides us.

We are not trying to make left-handedness feel special. We simply want to make everyday tools that feel right in the left hand.
