Where this comes from

My grandmother said it over a bath

There is a word we say when something useful is thrown away. — mottainai. It is not a polite word. It is closer to a small cry of pain.

She said it not over the money, but over the water — still warm at nine in the evening, and about to go down the drain unused.

She was not poor. She had lived through a time when things were scarce, and she never lost the habit of looking at a thing twice before letting it go.

That is the whole of what I am going to teach you. Everything else in this book is detail.

You are here because a bill got larger than it should be. Perhaps the electric bill in August. Perhaps a contractor who wanted three thousand dollars for a job that turned out to be four hours of work. Perhaps the grocery bill, which no longer makes sense to anyone.

I cannot fix your country's prices. What I can do is show you what a Japanese household does when the same pressure arrives — because Japan has had that pressure a very long time. Little land, hot wet summers, cold houses, expensive fuel, and a deep dislike of waste.

Out of that came several hundred small practical habits. About a hundred of them work just as well in Ohio or Florida as they do in Kyoto.

The idea behind Chapter One

Stop the heat at the window, not in the room

Almost everyone fights the heat inside: curtains, blinds, a fan pushing hot air around, and the machine running all afternoon. But by the time sunlight is inside your glass, it has already become heat — and heat does not want to leave.

The Japanese answer is older and simpler. Stop it outside, before it ever gets in.

Method 1 — the sudare, hung a few inches outside the glass. Eight to thirty dollars a window.

How every method is written down

What it costs. What it saves. And where it goes wrong — those red boxes are the most valuable part of the book.

Grow a green curtain

— midori no kāten

After 2011, when Japan lost a large part of its generating capacity overnight, city governments handed out seeds. The idea was a living screen up the sunny side of the building — bitter gourd, morning glory or cucumber on a net. A leaf does two things a reed screen cannot. It blocks the sun, and it releases water vapour. It is the only shade that is actively cold.

Costs / saves$12–$25 for net, hooks and seed. An hour to set up, five minutes a day to water. Shading plus evaporation make a real difference to the wall behind it — and the bitter gourd feeds you.
Where it goes wrongPlant too late and all you have is a net. Four to six vines at the base, in spring, watered daily through the heat.

Use the kelp twice, then eat it

— tsukudani

The kombu you pulled out of the dashi pot is not finished. Simmer it a second time for a weaker broth to cook rice in. Then slice it thin, simmer with soy sauce, a little sugar and vinegar, and you have a salty relish that keeps a fortnight in the refrigerator and turns a bowl of plain rice into a meal. Three uses from one strip of seaweed — the whole philosophy of the chapter in one ingredient.

Costs / savesNothing at all. It is the same strip you already bought, doing two more jobs.
Where it goes wrongNever boil the kelp in the first place. It turns bitter and slimy, and that is the only way to get dashi wrong.
60

Keep a scrap bag in the freezer

My wife has never once called this economising. It is simply how a kitchen is run.

One bag, always in the same place in the freezer door. In go onion skins and ends, carrot peel, celery tops, herb stalks, parmesan rinds, mushroom stems, corn cobs, leek greens, chicken bones. Nothing is bought for that bag, and nothing in it was ever going to be eaten. Once a week it becomes stock, and the stock becomes the base of three meals.

Costs / savesOne freezer bag. The average American household throws away close to a third of the food it buys — this is the quietest leak in the budget, and the easiest to close.
Where it goes wrongLeave out cabbage and broccoli in quantity — they turn it bitter and sulphurous. No potato peel, which clouds it. Nothing mouldy.

Walk the property and find the standing water

— mizutamari

A traditional Japanese garden should be full of mosquitoes — stone basins, dense shade, wet bamboo, still air in August. And yet you sit in one at dusk and are barely bitten. The reason is not a secret compound. A mosquito needs still water for about a week to complete its cycle. Remove the water and you remove the mosquito, permanently, in a way no spray achieves.

Costs / savesTwenty minutes after rain. Look at saucers under pots, the gutter, a tarpaulin fold, the tray under the outdoor unit, an old tyre, the bird bath.
Where it goes wrongSpraying kills the generation in front of you and leaves the next one's food supply untouched.

A plain word about this book

Three things it will not do

It will not invent numbers

Savings are given as ranges, because your house is not my house. Anyone who tells you a screen makes a room "fifteen degrees cooler" is guessing and hoping you don't check. I would rather be dull and right.

It will not send you up a ladder

Nothing in here needs a contractor. Where a method touches house wiring, gas, the structure of your roof, or the canning of low-acid food, I say so plainly and tell you where to stop. There is no pride in a low bill and a house fire.

It will not hide a correction

Where I have got something wrong before — the twenty years of food storage, the borax for pests — I correct it in front of you rather than quietly. I would rather be a man you can trust than a man with a better headline.

And one thing said openly: the Sensei is the narrator of this manual and of the videos it comes from — a character, in the way the storyteller in an old household book is a character. The methods are not invented. Every one is a real practice with a real Japanese name, or a plain piece of household work any careful person can check.

In closing

A letter from the Sensei

Not one method in these pages will change your life. A reed screen at a west window saves a modest amount. A hot water bottle saves a modest amount. A bag of scraps in the freezer saves a modest amount. Any one of them, on its own, is barely worth the twenty minutes.

Twenty of them, kept up for a year, is a different matter entirely — and the ones that cost nothing at all, the habits rather than the purchases, are the ones that add up fastest.

So I will ask you to do something small. Not all of it. Choose three.

  1. One from the chapter that matches the bill that hurts most this month.
  2. One from Chapter 6, because the kitchen is where the money leaks quietly.
  3. And method 100, the ledger, because it is the one that makes all the others visible.

Do those three for thirty days. Then open the book again and choose three more.

— The Sensei

Before you buy

Is this manual for you?

Yes, if

  • A bill got larger this year than it should have
  • You'd rather do three things well than read about thirty
  • You want to be told plainly where a method stops working
  • You like knowing why something works, not only that it does

No, if

  • You want one trick that cuts the bill in half
  • You want guaranteed dollar figures rather than honest ranges
  • You're looking for a book about Japanese design or philosophy
  • You won't do the slow ones — some of this pays back over years

Questions

Anything else?

How do I read it?

After paying you get an email with a link. Click it and the manual opens — on a phone, a tablet, or a computer. There is nothing to install and no account to make. It was laid out to be printed, so if you'd rather have it in the kitchen drawer, print it.

Will this work outside Japan?

That was the test for every method that made it in. About a hundred of the several hundred Japanese household habits work just as well in Ohio or Florida as in Kyoto — the rest were left out. Where a method needs a particular climate, the book says so.

Is any of it dangerous?

Four things are where careful people get hurt: house wiring, gas lines, roof structure, and the home canning of low-acid food. Each is dealt with in its own chapter, with the guidance you should follow and the point at which you should call somebody. Nothing in the book asks you to improvise on those.

Is my payment safe?

Yes. Payment is handled by Gumroad, which processes purchases for many thousands of independent writers. Your card details never reach me.

What if something goes wrong?

Write to me at hello@thejapanesehomemanual.com — a lost email, a link that won't open, a method that didn't work in your house. I read everything, and the second edition will be better for it.
