Tokyo SEO and content firm behind the TACT SEO tool, also active in M&A
About Willgate
Willgate Inc. (Kabushiki Kaisha Willgate) is a Tokyo company founded on 20 June 2006. Its head office is on the third floor of Omotesando Granbell in Minami-Aoyama, Minato-ku, and it had 140 people, counting employees and freelancers, as of April 2026. Paid-in capital is 60 million yen. The firm now runs three lines of business: M&A advisory for ventures and IT companies, content marketing, and sales tech built around seminars and social selling.
Representative Director Riki Kojima leads the company, with Senior Managing Director Yoshioka hosting a business YouTube channel that features other company founders. The content marketing arm covers SEO consulting, article production, help bringing SEO in-house, an online editing team service called EditorU, and the Promonista marketing media site, which publishes long guides on SEO for sectors such as manufacturing and B2B.
The SEO consulting process has four steps: enquiry, an online hearing, research and analysis to pin down problems and causes, then an improvement proposal. Clients receive a monthly report. Consulting does not include making changes on the site; hands-on implementation is an add-on. A site diagnosis is free on request, and the firm also offers a local SEO and MEO service, the Japanese term for Google Business Profile and map optimisation. Willgate has supported more than 7,700 companies with web marketing, over 3,600 with SEO and over 4,400 with article writing.
Willgate also builds TACT SEO, software that automatically surfaces SEO issues from keyword research through content analysis, with backlink checks, site audits, rank tracking and AI writing. About 7,000 companies use it, and in summer 2026 it took the Leader badge in the ITreview Grid Award SEO tools category, its 24th consecutive recognition. On ITreview it scores 4.3 from 133 reviews, with support quality rated highest at 4.6 and price lowest at 3.9.
They have no dental, clinic or medical case study. The nearest is a seitai (manual therapy) media site that reached top positions for its main keywords within six months and lifted organic traffic by 50 percent, using articles checked by specialists. Other published cases include SBI Insurance reaching first place for the car insurance keyword and Marui's fashion rental service growing sessions about 34 times. Dental clinics in Japan that need content reviewed against the medical advertising guidelines should ask directly how Willgate handles that, as it is not described publicly.
Prices are not published. Quotes depend on site size, issues and the volume of work, and plans can be shaped to a budget. No minimum contract length is stated; support is planned as a long-term engagement and adjusted case by case. SEO training plans let in-house staff learn while working beside the consultants, which may appeal to dental groups that want to write their own content later.
