Plug-and-Play Office Delivered in Shin-Yokohama; Sun Frontier Fudousan
Sun Frontier Fudousan has completed THE PORTAL SHIN-YOKOHAMA, an office building in Shin-Yokohama 2-chome, Kohoku Ward, Yokohama, where the company had been undertaking a renovation. The building was delivered on January 15, 2026. The project involved a full-building renovation of an existing office property and marks the company’s first plug-and-play (move-in-ready) office offering in the Yokohama area.
The building is a steel-reinforced concrete (SRC) structure with nine stories above ground, with a gross floor area of approximately 772 tsubo (approx. 27,470 sq. ft.) and a site area of approximately 119 tsubo (approx. 4,234 sq. ft.). Office floors span levels 2 through 9, enabling tenants to select suites suited to their growth stage, from approximately 12 to 60 people. Shared amenities include meeting rooms, a lounge, and web-conferencing booths, and select floors also provide furnished workstations.
The company has been expanding its plug-and-play office business in earnest since 2013, having supplied more than 900 suites cumulatively and currently managing 800+ units. As major developers continue to expand offerings—such as Nomura Real Estate’s PMO (about 50 buildings) and Nippon Steel Kowa Real Estate’s BIZCORE (11 buildings)—competition has intensified. Roughly 30% of tenants are startups less than five years old, and the company has captured demand from growth-stage firms through offerings such as zero security deposit and proprietary rent schemes.
In Tokyo’s 23 wards, the number of flexible office locations grew from 569 in 2020 to 1,777 in 2024, roughly tripling over five years, and competition is becoming tougher as major developers enter the space in earnest. Overall occupancy across the company’s PM-managed properties remains high at 90%+, with its in-house leasing and property management platform serving as a differentiator. Shin-Yokohama is a terminal station served by five rail lines, and the company aims to secure additional growth potential by expanding beyond central Tokyo.
