Portrait of Naomi Nakamura
A note from the author

“I have written this for a woman who has been sold things her entire life and has stopped believing most of it.”

I have run a household for twenty-five years. That is not a credential I ever expected to put on anything. I was not trained for this work. I learned it the way most women learn it: by making mistakes in front of people I loved, and by watching my mother make them too, and by deciding, eventually, that there had to be a better way to spend a life than fighting the same stains, the same smells, the same worn-out pans.

The first book is the complete list of what I changed in the house. The second one stays at the stove. I have cooked in small kitchens with one good saucepan, an old rice cooker and thirty minutes before someone asked when dinner would be ready. Most of what I learned there were small habits — water, heat, timing — the details that disappear when a recipe is shortened for the internet.

Neither book asks you to buy much. They are about spending less, wasting less, and doing the small things in the right order.

The Replacement Principle

Things are designed to be replaced. This book is not.

Learn how to care for, repair, and stop replacing everything in your home — from the kitchen to the bedroom. 16 parts, organized by object, not by chore: the pans, the towels, the closet, the fridge, the cleaning cabinet and the 23 bottles you can stop buying.

The argument

Things are designed to be replaced. This book is not.

Most household objects sold in the last twenty years were engineered to a service life shorter than their materials allow, because a shorter service life is a better business model than a longer one. The cleaning products sold to maintain them follow the same logic: fragrance, not function, is what gets repurchased.

None of this is your fault. You were not taught which nineteen ingredients actually do the work, because there is no profit in you knowing nineteen ingredients. You were taught to buy forty-one products instead. This book is the nineteen ingredients, applied to nine hundred pages of specific objects in your specific rooms.

What this saved you, the ledger one year on, teaching others, objects you’ll keep forever, what changes when you stop buying, starting anyway, the last chapter.

Why this book works

The core principles that change everything

These four ideas are the foundation of every chapter. They’re simple, practical, and they work.

🧴

5 Ingredients Replace 23 Bottles

Vinegar, baking soda, citric acid, mild soap, and bleach. That’s all you need to clean your entire house.

🔧

The 12 Tools You Actually Need

No more gadget drawers. A chef’s knife, a cast iron pan, a wooden spoon, and nine others. That’s it.

⏱️

The 2‑Minute Daily Reset

Five tasks, two minutes each, every day. The house never gets messy enough to need a deep clean.

📒

The Replacement Ledger

Write down what you buy, what it cost, and how long it lasted. One page that saves you thousands over time.

Said plainly

What The Replacement Principle will not do

A book that only tells you what it can do is a book that hasn't been tested on a real house. Here is what it won't.

✕

It will not make your house tidy on its own.

This is a book about caring for objects, not a system for organising a room.

✕

It will not fix an object that is already ruined.

A cutting board split all the way through, a pan warped past flat — some damage is past the point where care helps.

✕

It is not medical advice.

Nothing diagnoses, treats, or replaces guidance from a physician.

✕

About a quarter of its chapters conclude: leave it alone.

Some finishes, fabrics, stains are made worse by intervention. The book says so.

✕

It will not work faster than the object allows.

Cast iron needs seasoning. Grout needs sealant. Forty minutes means forty minutes.

✕

It will not replace your appliance’s specific product.

Where a warranty depends on a named product, the book tells you up front.

The Japanese Kitchen Fix

53 everyday recipes — and the small techniques that make them work.

Rice that isn't wet. Chicken that browns before it steams. Miso soup that doesn't taste harsh. Naomi explains the small Japanese home-cooking habits recipes usually skip — written for an ordinary American kitchen and ordinary supermarket ingredients.

The small techniques

A few habits that travel between recipes

Better cooking usually does not require better ingredients. It requires knowing what to do before the food enters the pan — and when to stop touching it.

🍚

Rinse, Measure, Rest

Gentle rinsing, drained rice, measured water and a closed lid while it rests. That is most of good rice.

🍲

Dashi Without Mystery

Kombu for depth, bonito for aroma — or low-sodium broth on a weeknight. It changes the flavor, and that is fine.

🍜

The Order of a Ramen Bowl

Hot broth, seasoning, cooked noodles, toppings. Warm the bowls and cook noodles separately.

🍗

Keep Crisp Food Out of Steam

Dry before coating, fry a few pieces at a time and drain on a rack so steam can escape.

Also in the book

More than a list of recipes

Two five-day dinner plans

Use the same pantry more than once. Prep rice, scallions and sauce once, then cook through the week.

Troubleshoot by what you see

Chicken is gray. Rice is wet. Coating is greasy. Miso soup tastes harsh. Find the cause and the fix.

The pantry you actually need

About ten core ingredients — soy sauce, miso, mirin, rice vinegar, potato starch — not a $300 imported pantry.

What The Japanese Kitchen Fix will not do

✕

It will not pretend to be a restaurant cookbook.

These are home-style dishes. Where a recipe is Naomi’s own adaptation, it is labeled that way.

✕

It will not send you to three specialty stores.

Most recipes use ordinary supermarket ingredients, with practical substitutions where they genuinely work.

✕

It will not ask you to buy Japanese equipment.

A skillet, a lidded saucepan, a sheet pan and a thermometer cover most recipes. No donabe required.

✕

It will not trade food safety for tradition.

Safe internal temperatures follow current USDA guidance, and every recipe says when to use a thermometer.

One book covers every object in your home — the pans, the towels, the closet, the cleaning cabinet. The other stays at the stove: rice, noodles, chicken, fish and the small habits that make them work. Both start from the same idea: learn the small things before you buy anything new.

This book is newly published, so there isn't a long list of reviews yet. Real ones will be added here as they come in — nothing on this page is invented.

★★★★★

“This book has already saved me from buying a new cast iron pan. The instructions were so clear and it worked perfectly. I wish I had this years ago.”

Sarah M., Austin, TX
★★★★★

“I'm not a handy person, but this book made me feel capable. The grout section was a lifesaver. My bathroom looks brand new.”

James R., Portland, OR
★★★★★

“Finally, a practical guide that doesn't assume I have a workshop full of tools. The '19 ingredients' approach is genius. Highly recommend.”

Elena K., Chicago, IL
