What At Office does
At Office is a Tokyo-based commercial real estate brokerage and property services group specializing in small-to-mid-scale office leasing for venture/startup companies, doctors opening new clinics, and small-to-medium building owners. The company operates a multi-brand platform including at-office.jp (commercial office property search), at-clinic.jp (clinic-specialized property search), and bldg-ad.jp (national office property aggregator), collectively covering more than 100,000 properties with approximately 17,000 active vacancy listings across Tokyo, Kanagawa, Chiba, Nagoya, and Osaka. Service delivery is one-stop, spanning property search, brokered leasing, master-lease/sublease arrangements, interior design and construction (in-house construction license), rent guarantee (At Safety), and increasingly M&A and succession matching (at M&A).
The group is structured under At Group Holdings and includes four core operating subsidiaries alongside the parent At Office entity: At Clinic (medical property and opening support), At Safety (rent guarantee co-developed with TSE Prime-listed J-Lease), BiluAdo (B2B real estate media and data), and Startup Capital (venture capital). Technology investments center on the property database platform, proprietary Tokyo office market research (station-level rent-per-tsubo reports and ward-level vacancy analyses), and an exclusive commercial-real-estate deployment of Urbanbase Studio for 3D spatial simulation and VR visualization. Content marketing through Venture.jp (380+ entrepreneur interviews as of April 2025) and a free community event space at the Minami-Aoyama HQ drive top-of-funnel demand.
The business model is multi-stream and asset-light: transaction commissions on brokerage deals, rental spread on master-lease/sublease positions, professional services fees from interior construction, recurring subscription fees from the At Safety rent guarantee product (both upfront Standard and installment Subscription plans), and referral/listing fees from the BiluAdo aggregator. Pricing is not publicly disclosed for brokerage commissions, but the rent guarantee product is transparently priced (¥100-300/month transfer fees, 50-100% upfront guarantee fees, 3%/month or 10%/year recurring). Customer acquisition is sales-led via freephone (0120-095-889), inbound website forms, and field sales through regional offices in Yokohama (opened May 2023) and Osaka (opened October 2025).

At Office competitors and assessment
Company assessmentBroad incumbents
- Mitsui Fudosan: Japan's largest real estate developer with extensive commercial office leasing, brokerage, and asset management operations. Comparable as a broad incumbent in the same commercial office market, but operates at national scale across multiple property tiers rather than focusing on small-mid niche.
- Tosei Corporation: Tokyo-based real estate services firm engaged in property acquisition, revitalization, brokerage, management, and rent guarantee. Comparable as a more diversified real estate services peer covering brokerage, property management, and rental guarantee — overlapping significantly with At Office's full-stack model.
- LIFULL: Operator of Japan's LIFULL HOME'S real estate portal and adjacent property data services. Comparable as a broad incumbent in property search aggregation with overlap on At Office's BiruAdo aggregation platform and SEO-driven lead generation channels.
- Mitsubishi Estate: Major Japanese real estate developer with deep commercial office leasing portfolio concentrated in Tokyo Marunouchi area. Comparable as a large incumbent offering office leasing and property management services, but skews toward premium/large-ticket tenants and owned assets rather than small-mid brokerage.
- Hankyu Hanshin Properties: Japanese real estate services company affiliated with Hankyu Hanshin Holdings, operating leasing, brokerage, and property management primarily in Kansai (Osaka) and other major cities. Comparable as a regional incumbent providing office leasing and management, directly relevant to At Office's new Osaka expansion.
Emerging players
- GA technologies: Tokyo-headquartered real estate technology company using AI and digital tools for property search, brokerage, and renovation services. Comparable as a tech-forward peer attacking traditional brokerage with proprietary technology and vertical integration in the residential-to-commercial space.
- I Seikatsu (いい生活): Japanese real estate technology SaaS provider offering cloud-based brokerage and property management software to real estate agencies. Comparable as a tech infrastructure peer enabling real estate intermediaries with workflow and CRM tools used by firms like At Office.
Direct peers
- IELOVE (いえらぶ): Japanese real estate technology company providing cloud-based brokerage SaaS, lead generation, and listing platforms primarily for residential but expanding into commercial. Comparable as a tech-enabled real estate services peer pursuing digital intermediation across brokerage workflows.
Regional players
- IWG Japan (Regus): Japan operations of IWG, the global flexible workspace provider (Regus/Spaces/HQ brands). Comparable as a regional office space competitor pursuing the same small-business and corporate satellite-office demand through flexible lease products, an alternative to traditional brokerage like At Office.
- WeWork Japan: Japan subsidiary of WeWork operating flexible/serviced office spaces across Tokyo, Osaka, and other major Japanese cities. Comparable as a regional office space provider competing for the same small-mid tenant and startup customer base, though delivering via shared-space model rather than lease brokerage.
