Why a Japanese home feels calm, and an American one feels like work.

Every habit people call Japanese discipline turns out to be a floor plan, a fee, or a law. Two Houses measures each one, and what it means for your house tonight.

問いToi · A question first

Before you buy anything, try this tonight.

The back of the book holds ten cards, two questions for each part of the house. Pick a room and ask it the two questions. That's the method, and you can start before you spend a cent.

The CounterChapter 13, one of ten cards
一Does this live here, or is it just resting here?
二If it were in a cupboard, would I get up and go and get it?

Cupboard, not garage. Two weeks.

Nobody in my mother's house was disciplined. The closet was eighty centimetres deep.

A futon folded in three is about seventy-five. So the bedding goes away every morning, because there is exactly one place for it. Americans call that a habit. It's a cupboard. The whole book works this way: find the measurement under the behaviour.

間取りMadori · Measured

Two houses, side by side.

The house I grew up in and the house I live in now. Some rows go America's way. The book says so twenty-five times, and means every one.

手紙Tegami · A letter

Everyone here calls me Ken. My mother still calls me Kenichi. I have now lived in America longer than I lived in Japan, which makes me the wrong person to romanticise either country and the right person to measure the wall between them.

I am not the good example. I own a garage that has never held a car, central heating I love, and a kitchen drawer I could not describe under oath. I am writing from inside the American house, not from above it.

“I am an older American and I grew up with my mind being on what others would think. You've described it so clearly, like I have not heard it before.”

質問Shitsumon · Questions

What people ask before they buy.

Is this a printed book?

No. It's a digital book: a PDF, 543 pages, set at 6 by 9 inches in large type. It reads like a printed book on a tablet, and you can print any or all of it. Nothing arrives in the post.

How do I open a PDF?

You already can. Every iPad, iPhone, Android phone, Mac and Windows computer opens PDFs without installing anything. Tap the link in the email and it opens.

Can I read it on a Kindle?

Yes. Go to amazon.com/sendtokindle, sign in, and drag the file onto the page. On a small, basic Kindle the pages look small; it's far better on an iPad, a computer, or paper.

Is my card information safe?

Yes. I never see your card. Payment is handled by Gumroad, and PayPal and Apple Pay work too.

Will the price go up?

Yes. $47 is the early-bird price until 11:59 p.m. Eastern on October 31. On November 1 it moves to $79.

What if it isn't for me?

Email twohousesbyken@gmail.com within 30 days and I'll refund you. No form, no questions.
