The real features of the sharehouses of Interwhao!

shinjuku studio apartment party in sharehouse Introducing Interwhao's experienced house manager!

Interwhao sticks to the basic style of sharehouse!
Welcome to Interwhao!

  • Feature1
    All rooms are completely private rooms!

    Interwhao considers that a private space is essential to sharehouses, even if they are houses to share.Everyone needs some time to study and work alone to focus on. Understanding occupants' request, we are taking care of the atmosphere of our rooms to let them live comfortably.

  • Feature2
    The center of interactions with others is a nice living room!

    Interwhao has had shahouses since old times in which dozens of people socialize with others.Living rooms and lounges where people gather are the center of a sharehouse life.To let occupants enjoy comfortably, and gather naturally, we are aiming to offer them an exciting and playful space with them.

  • Feature3
    Every staff can speak English, and has lived in a sharehouse.

    Because almost all of our staff are living or have lived in a sharehouse, they know most of what is fun, and what troubles you. This experience makes us to share occupants' thoughts, and support them not as a businesslike relation. We think that we would like to prepare a comfortable life space of the sharehouse in which we, our staff and the occupants, are able to convey each feelings.

  • Feature4
    Enjoyable human relations under the rules and the manners.

    In a sharehouse, rules and manners are needed to live comfortably because in which living room and a kitchen are shared. We explain the rules and manners in advance to people who want to live in a sharehouse. Only people, who can obey the rules and the manner, can live in the house. In a life of sharing, to obey rules and manners, and kindness to others are important. The views and the senses of value expand by interaction with others in a sharehouse whose nationality, gender, and occupation are different from others, said some occupants. Please think that the premise is the observance of the rules and the manners of sharehouse.

  • Feature5
    Events and parties are the chances to get on with others?

    There are many sharehouses in which events and parties such as Halloween, Christmas, fireworks, and BBQ are held naturally by the people who had lived in the house before, who is living in our other sharehouses and other apartment. Why don't you join in the events and the parties to get on with many people? Through events, becoming good friends with other occupants and hanging out together are not a rare case at all. After a good conversation with someone, you will say "Hi!" and smile naturally next time you see him or her.
