Tokyo, Japan, November 18, 2021 – Mitsui Fudosan Co., Ltd., a leading global real estate company headquartered in Tokyo, and group company ShareTomorrow hereby announce the launch of the HUBHUB Project, which sets up mobile units to create venues for in-person gatherings at under-utilized properties. As a pilot facility for the project, HUBHUB Nihonbashi Ningyocho will open on Monday, November 22, 2021 at 1-8-9 Horidomecho, Nihonbashi, Chuo-ku, Tokyo.

In launching the project, we chose a highly convenient model location for the pilot facility HUBHUB Nihonbashi Ningyocho, which represents the kind of under-utilized property that we intend to use. It is three minutes’ walk from Ningyocho Station on the Toei Asakusa Line and Tokyo Metro Hibiya Line.

The facility combines three types of units― accommodation, party room, and pool. The concept is “an accommodation facility with leisure activities, not just a place to stay.” HUBHUB Nihonbashi Ningyocho will be the only mobile accommodation facility operating in downtown Tokyo.*

ShareTomorrow was founded in July 2021 as a Mitsui Fudosan Group company responsible for the development and promotion of new businesses. The company plans to launch multiple new projects in fiscal 2021.

1. About the HUBHUB Project

1) Reasons for Launching the HUBHUB Project

Many properties exist in urban areas that are difficult to utilize because of limited land area and limited usage period. As well, consumers are seeking more variety in functions provided by accommodation facilities amid diversifying lifestyles. The HUBHUB Project was launched with the goal of developing facilities that are mobile and flexible in terms of size and function to create convenient, vibrant hubs that prevent the hollowing-out of urban neighborhoods, enrich and enhance people’s lives, and model a new lifestyle. Going forward, the Mitsui Fudosan Group will combine the project with its mobility service and other businesses to provide new experiential value that improves user convenience. The HUBHUB Project uses the MAG!C project proposal system, which attracts diverse business ideas from Mitsui Fudosan Group companies.

2) Concept, Brand Name, Logo

The project was born from the wish to enrich and enhance our lives by providing a space where we can meet friends in person. Based on a concept of a facility comprising mobile units, each with specialized functions, which adds totally new value to the lives and interests of local residents and office workers, the HUBHUB Project will deliver spaces that families and groups can enjoy.

The meaning of the brand name is a service that provides a hub (a place away from home that can be used with like-minded friends) to enrich and enhance your daily life.

The logo design expresses the existence of multiple hubs, the spread of free lifestyles, and expectations and excitement about a new service in the form of two overlapping hubs. The overall color tone is bright, reflecting our hopes for an accessible service that makes users feel positive.
