What PLUS ONE does

PLUS ONE (株式会社プラスワン) is a privately held, Kyoto-headquartered digital marketing agency founded in March 2010 in Uji City, Kyoto Prefecture. The company operates with a small team of approximately 10 employees (as of August 2024; average age 29) and serves Japanese SMB and mid-market clients in the Kansai region. Its service portfolio rests on three pillars: (1) owned media operation centered on the finance vertical through its proprietary sub-brand Fincle (フィンクル), an SEO-driven financial information platform covering loans, credit cards, and tax topics with all content reviewed by certified Financial Planners (FPs); (2) search engine listing advertising (SEM) management across Google and Yahoo! Japan, for which PLUS ONE holds Google Partner and Yahoo! Marketing Solutions Partner One-Star certifications; and (3) landing page production for conversion optimization. The three services are deliberately integrated: paid traffic is converted through PLUS ONE-built landing pages, while Fincle captures organic demand and generates affiliate revenue.

Underlying technology is conventional web marketing infrastructure — CMS-driven SEO content publication, Google Ads and Yahoo! Japan advertising platform management, and manual landing page design — without disclosed AI/ML components. Business model mechanics consist of (a) monthly retainer fees for advertising operations and consulting engagements with client companies across finance, real estate, education, and e-commerce, and (b) affiliate commissions and sponsored content revenue from Fincle's referrals to Japanese financial product providers (lenders, credit card issuers). Go-to-market is sales-led and hybrid B2B/B2C: direct sales outreach with face-to-face discovery meetings for client services, supplemented by Fincle's organic content funnel for consumer-facing revenue.

PLUS ONE is registered with ¥10,000,000 in capital, has no external investors or parent company identified, and has shown modest scaling via three office expansions (Nijo 2013, Karasuma-Oike relocation December 2016, floor expansion August 2023). The company has no subsidiaries, no M&A activity, and no disclosed external funding; its 15-year operating history and steady growth posture indicate a self-funded, lifestyle-stage small business rather than a venture-backed scale-up.

Core offering

PLUS ONE is a Kyoto-based digital marketing agency that plans and executes search/display advertising campaigns on Google and Yahoo! Japan as a certified partner agency, designs and builds conversion-optimized landing pages tied to those campaigns, and operates its own consumer finance media platform Fincle with FP-certified editorial content. Its core commercial offering combines advertising operations and landing page production as integrated client engagements, supplemented by owned media operation and web consulting services.
