Most budgeting apps track where your money went. Kakeibo asks where it should go — before you spend it. It's a 120-year-old Japanese journaling method, and it works better than any app I've tried.

The 4 questions

At the start of every month, write down:

1. How much money do I have coming in?

2. How much do I want to save? (Set this BEFORE expenses — this is the key difference.)

3. How much am I spending? (Sort into 4 categories: Needs, Wants, Culture, Unexpected.)

4. How can I improve? (Review weekly. One small adjustment each time.)

Why it works

Kakeibo forces you to write by hand. No spreadsheets. The physical act of writing makes you 42% more likely to follow through (research from Dominican University). You also categorize spending into 4 buckets — Needs, Wants, Culture, and Unexpected — which eliminates the "where did my money go?" feeling.

Try this today

Grab a notebook. Write this month's income at the top. Below it, write your savings target. Subtract both fixed bills and your savings target. What's left is your actual spending budget. Divide it by 4 weeks.

That weekly number is your real budget. Spend from that. Track daily in 30 seconds.

This is just one method from Chapter 1 inside The Japanese Method. We go deeper into envelope systems, the 「先取り貯蓄」(pay-yourself-first) approach, and seasonal spending rhythms that Japanese households use to stay ahead.
