Japanese Minimalism: How Owning Less Reduces Stress, Improves Your Health, and Prolongs Your Life

“The 9 Japanese Secrets” Series • Article #9

In Okinawa, home to some of the world's longest-living people, it is rare to find a house full of unnecessary objects, overcrowded closets, or storage rooms full of things "just in case".

A 104-year-old grandmother can live happily in 25 m², with few pieces of furniture and just three pairs of shoes.
And modern science is beginning to show why this minimalist, functional, and emotionally light lifestyle is one of the great secrets of their longevity.

⭐ Why can having less help you live longer and better?

Japanese minimalism has nothing to do with white aesthetics, perfect houses, or magazine photos.
It is a practical philosophy that frees up physical, mental, and financial space.

Proven effects:

• Fewer objects = less daily cortisol
  Fewer decisions, less visual chaos, fewer pending tasks.

• Fewer impulse purchases = less financial stress
  Anxiety about money is one of the factors that ages you the most.

• Clear spaces = better sleep and less anxiety
  According to a Japanese study from 2022.

• More time and energy for what really matters
  Relationships, nature and movement: the true pillars of longevity.

A study from Kyoto University found that people over 80 years old who live with fewer than 300 personal items have 40% fewer inflammatory markers than those who live surrounded by clutter.

Fewer things ≠ less life.
Fewer things = more calm , more energy , more years .

⭐ The 4 Japanese rules of minimalism applied by centenarians

1. Ichigo-ichie with the objects

Each object must fulfill one of two functions:

• be useful,

• or give real joy.
  If not, it is let go.

2. One in, one out

If you buy something new, something else has to come out.
That way you never accumulate again.

3. The 100-day drawer

Put anything you're unsure about in a box.
If 100 days go by and you haven't missed him... he leaves without guilt.

4. Mottainai

It means “what a shame to waste”.
Repair, reuse, give away before throwing away.
It's about respect, sustainability, and gratitude.

⭐ 30-Day Japanese Minimalist Plan (No Stress)

Week 1
Observe: open one drawer or cupboard a day and write down what you haven't used in 12 months.

Week 2
Sort into three bags:

• sell/donate

• give a present

• throw

Week 3
Apply "one in, one out" to any purchase.

Week 4
Test the 100-day drawer with what you still find hard to let go of.

Typical results by day 30:

✓ Sleep better from the first week
✓ 5–10 free hours that were previously spent on ordering
✓ Fewer impulse purchases
✓ Greater mental clarity
✓ Lasting feeling of control and lightness
