A century-old Japanese method that transforms our relationship with money through awareness and simplicity.
羽仁もと子 • 1873–1957
The first woman journalist in Japan, Hani Motoko revolutionized household finance by creating the Kakeibo in 1904. She believed that financial independence began with awareness of every single expense.
In 1904, as Japan was opening up to the modern world, Hani Motoko published the first Kakeibo — literally "household account book".
Her idea was radical for the time: give women a tool to understand and master the household finances. Not through complex calculations, but through a simple act: mindfully writing down every expense.
More than a century later, this method remains strikingly relevant. In a world of invisible payments and one-click purchases, the Kakeibo brings us back to what matters.
« The secret to saving is to mindfully record every expense, no matter how small. »

The Kakeibo invites us to ask these questions every month
Know your real situation. Income, fixed charges, what's left. No illusions.
Set yourself a goal. Even a small one. What matters is having a clear intention.
Log every expense. The act of writing it down creates awareness. That's where everything changes.
Analyze, understand, adjust. Without judgment. Just the will to make progress.
What makes the Kakeibo different from other methods
Writing by hand (or typing it in yourself) creates a connection between action and awareness. No automatic bank sync — that's the point. The effort of logging is what creates change.
Before you spend, you set your situation. Income, charges, savings goal. You know exactly how much you can spend. No surprises at month-end.
Every month, you analyze. What was necessary? What wasn't? No self-judgment — just learning. And next month, you do better.
No complex categories, no fancy charts. Just the essentials: what comes in, what goes out, what's left. Clarity comes from simplicity.
Kakei humbly draws from this century-old philosophy, adapted to the modern world.
