    Firsthouse Omori is only 8 min walk from Omori station in JR Keihin Tohoku Line where it is 2 next stops from Shinagawa station. You can go to Yokohama station by train for 18 min. Therefore, it’s very easy to go not only to Tokyo direction but to Yokohama area!Supermarkets, convenience stores, and drug store are very close to the sharehouse so this environment must be convenient compared to other areas in Omori.  Common spaces and some rooms have been renovated in 2017, so you may really like this sharehouse!

    The size of all rooms are about 10㎡ with good sunshine!! Shower rooms and bathrooms are separated in men and women. And the entrance is electric auto-locked so the security is good!! Since it is close to the station, it is convenient to go for shopping at a supermarket, convenience stores, book stores, drug stores, cafes, and so on.

Interwhao’s basic idea

SDGs are deeply ingrained in many governments and finances in the world, and are an important category in the living space we operate.
It is also an important value in the composition of the "Investment fund" which already supports the development of the economy.
Since our establishment in 2000, we have continued to provide comfortable living space for people with diverse values who gather from all over the world.
Our staff, like an airplane captain, play a stable role in providing living space.
A living space composed mainly of people in their twenties and thirties aims to give a better circular economy to society with kindness and vitality.
We also ask property owners and tenants to understand this sense of values. And we aim to continue and develop the provision of vital living space in the future.

A vibrant city and the shared values that take root in that city

The SDGs also consider housing as a crucial element as one of 17 basic goals.
We do not have our own development goals based on this idea.
However, we believe that there is something we can do.
We aim to provide living space where tenants realize growth and revitalize the building based on the shared economy philosophy.
We will provide as a common sense of value the provision of sustainable living spaces that can continue to provide peace and energy to a vibrant city.

The SDGs (Sustainable Development Goals), adopted at the UN Summit in September 2015, are the goals the 193 member states of the United Nations have set to achieve in the 15 years from 2016 to 2030.

Providing a living space where Interwhao can live for a long time

  • ・Reproduce existing building resources effectively.
  • ・Connect the residents who aim at self-realization through the living space provided by our company.
  • ・Bring energy to the town.
  • ・Borrow all or part of the available buildings and sublet them to corporations and individuals to revive their building resources.
