I'm Kenji. I grew up in a house where almost nothing was replaced, and it took me until adulthood to understand that was a decision rather than an economy.

The pan was the same pan. The board was sanded rather than binned. The cloth was washed. Things were chosen once, properly, and then kept.

Then I spent years working out why each of those choices was made, because the reasons turned out to be better than sentiment.

So that's what's here. What Japanese homes do differently in the kitchen, the bathroom, the laundry and the bedroom. What to replace, what to replace it with, and the reasoning underneath so you can decide for yourself rather than take my word.
