THE FIVE SKILLS
Money and life follow principles that don’t change with country or century.
The tactics – a cheap SIM, an investment account – change with where and when you live. But underneath them are five skills that never change. The same at home, the same in 100 years. This site simply translates those timeless skills into “how to do it in Japan.”
Babylon 5,000 years ago, and you today – the same problems
An old set of lessons from ancient Babylon says: “Keep a part of everything you earn.” “Make your money work for you.” “First, protect yourself and what you have.” Five thousand years old, yet they fit your life today perfectly.
Why? Because the root of money and life problems is the same, no matter the country or century. How do you protect, save, earn, grow, and spend? As long as people live, no one escapes these five.
So before any clever tactic, we start with these five unchanging skills. Tactics get old. Principles don’t.
The five skills, and their principle
Each skill has a principle that outlives any era.
- 1. Protect – First, don’t lose what you have. Guard yourself and your money from scams, disaster and trouble. No matter how much you earn, without protection it leaks out of a bucket full of holes. (In Japan, this foundation means “protect your visa (residence status).”)
- 2. Save – Always keep a part of your income for yourself. Babylon’s “keep one-tenth.” Not by suffering, but by building a system.
- 3. Earn – Sharpen your skills; grow your earning power itself. Become someone who can earn, rather than chasing quick money. (In Japan, you maximise this within the rules your visa allows.)
- 4. Grow – Let your money work for you. Babylon’s “make your gold have children” – investing. Put time on your side.
- 5. Spend well – Money exists to be used well. You protect, save, earn and grow so that, in the end, you can spend on the people and the life that matter.
Why the order matters
There is an order to build these in: Protect → Save → Earn → Grow → Spend. Always start from the foundation, “Protect.”
No matter how much you earn, if a scam takes it or a bad contract drains it, nothing is left. It’s like pouring water into a bucket full of holes. So first, plug the holes (Protect). Then fill the bucket (Save). Then pour more in (Earn, Grow). And finally, use it well. This order looks slow, but it is the fastest way.
Principles are universal. Practice is “Japan edition.”
The five skills themselves never change, anywhere, any time. But how you practise them depends on where you are right now.
This site translates these universal five skills into one specific situation: a foreigner living in Japan. Japan has complex rules that confuse even Japanese people – immigration law, taxes, social insurance, rental customs. The principle stays the same; only the “how to do it in Japan” is explained here, simply. If you move home, the practice changes – but this way of thinking will stay with you for life.
Explore each skill
Don’t lose it. Visa, contracts, health – the foundation of everything.
2. Save
Keep a part of your income. Cut rent, phone, remittance fees and taxes.
3. Earn
Sharpen your skills – and know what your visa allows you to earn.
5. Spend well
Family, culture, and the life you want to build here.
4. Grow
Some of this only works while you live here. Brokerage accounts, NISA, pension refunds.

Frequently asked questions
What are the five skills?
Protect, Save, Earn, Grow and Spend – in that order. They are timeless money-and-life principles that work in any country and any century.
Why does Protect come first for foreigners?
Because life in Japan rests on your residence status. However much you earn, losing the visa ends everything, so protecting it is the foundation.
Where should I start?
Start with Protect: health insurance, address registration and honest work within your visa rules. Then move to Save (as of 2026, all core guides are free on this site).
