The Ultimate Sanctuary
Executive Rental & Purchase Brokerage
"By improving your home, you improve your life itself."
YASHIRO Real Estate is more than a property listing service. We serve executives and high-net-worth individuals who want to live in a place with genuinely good "energy" in order to maximize their daily performance and business results — a rental and purchase brokerage service built entirely around the quality of space.
From a vast pool of listings and rare off-market properties, we curate "Iyashirochi" — land with little unwanted noise and high potential, evaluated through environmental engineering and geomancy. We primarily introduce properties with good "energy" that calm the mind and body and naturally draw out your inherent abilities.
Because we have absolute confidence in the quality of every space we propose, we also offer an "Ultimate Performance Guarantee" (a free or half-price next brokerage fee) for the rare case that the environment doesn't suit you after moving in.


Spatial Botany
Plant Selection to Draw Out a Space's Potential
Plants are the most natural way to elevate the fundamental quality of a space. Rather than placing greenery as mere decoration, we calculate a room's natural light and airflow to select the optimal tree form and species for that exact location.
Oversized symbol trees with the finest natural form, purchased directly from growers, bring the vitality of nature into an otherwise inorganic urban living space — delivering both visual comfort and a genuine sense of refreshment.
Strategic Interior
Furniture Selection to Clear the Mind and Sharpen Focus
We are unconsciously influenced by everything that enters our field of vision. Discordant colors and oppressive designs quietly drain your concentration — your cognitive resources — day after day.
At YASHIRO, we apply ergonomics and environmental psychology to eliminate visual and physical noise to the fullest extent, coordinating a total interior environment that keeps your mind clear and lets you perform at your best while staying deeply relaxed.

Pricing & Guarantee
*Standalone spatial assessments not tied to a property contract, or more complex environmental-engineering / Feng Shui assessments, are available on request (ASK).
In the rare event that you terminate your lease early after moving in because the property's "energy doesn't suit you" or "your performance has declined," the following guarantee applies:
- Move out within 6 months: your next brokerage fee is waived entirely (JPY 0).
- Move out within 1 year: your next brokerage fee is reduced by half.
