Hobonichi Techo 2027 HON Planner — Slash (Navy) A5

Hobonichi Techo began in 2001, when Shigesato Itoi's team built their planner from scratch — no other planner used as a reference, just what they wanted to use themselves. Twenty-five years later, the HON reworks that idea as a hardcover book you carry with no separate cover needed.

This Slash cover is one of HON's plainest options — a near-black navy cloth with a single gold-foil diagonal standing in for the slash mark used when writing a date. Inside is the 2027 Techo Cousin content in book form: a page a day on thin Tomoe River S paper, thread-bound to lay flat, plus a weekly page with an hourly timetable and the same 3.7mm grid running behind every day. It comes with two ribbon bookmarks, navy and beige, plus a clear pencil board with a pen loop.

Consider pairing it with a Hobonichi Techo Pencil Board — Ice Grey x Yellow — slide it under the page you're writing on for a smoother surface, and to keep ink from showing through to the next page.
