Business

Hatena Co., Ltd. is an internet technology company founded in 2001. Building on the technological capabilities and user community cultivated through UGC services such as Hatena Blog and Hatena Bookmark, the company operates three business-facing services: (1) Content Platform Service (UGC for individuals), (2) Content Marketing Service (Hatena CMS, toitta, etc.), and (3) Technology Solution Service (the manga viewer GigaViewer, server monitoring tool Mackerel, and contract development). The company has 12.89 million registered users (as of July 2025) and counts major companies such as Shueisha, KADOKAWA, and Nintendo among its principal clients. It is listed on the Growth Market of the Tokyo Stock Exchange.

Business Model

A structure in which technical capabilities and user base accumulated through the development and operation of proprietary UGC services are repurposed for corporate clients. Technology Solutions Service (net sales of ¥2,839 million in FY2025 (ending July 2025), up 23.0% year on year) is the mainstay, accounting for approximately 75% of the total. The design increases the proportion of recurring revenue: GigaViewer operates on a revenue-share model, Mackerel on a SaaS-type monthly subscription, and contract development on a maintenance/operation stock-type basis. Content Marketing Service (¥620 million) combines SaaS-type CMS with advertising. Financial soundness is also high, with zero interest-bearing debt and cash on hand of ¥2,136 million.

Company Strengths

The manga viewer "GigaViewer" had been adopted by 17 companies across 25 services (Web and app versions combined) as of August 2025. Its app version is embedded in Shueisha's "Shonen Jump+" (over 30 million downloads), establishing a structure that directly captures the growth of the e-comic market (¥5,122 million in 2024, up 6.0% year on year).

As of the end of FY2025 (ended July 2025), the company had zero interest-bearing debt and held cash and deposits of ¥2,136 million (equivalent to 6.8 months of average monthly sales). In addition, it has secured overdraft facility agreements totaling ¥1,700 million with five partner banks as a backup line, giving it an extremely stable financial base.

In FY2025 (ended July 2025), net sales were ¥3,794 million (¥34 million above forecast) and operating profit was ¥339 million (¥135 million above forecast, achievement rate of 167%). Operating profit surged 398% year on year, recovering sharply from ¥68 million in the prior period to ¥339 million, while ROIC improved from 1.8% to 8.3%. Free cash flow also expanded substantially, from ¥40 million to ¥673 million.

ENVALITH's Perspective

A loss of ¥1,180 million associated with a fund outflow incident was recorded as an extraordinary loss in the nine months ended Q3 FY2026 (ending March 2026). As a result, quarterly net loss before income taxes came to ¥1,076 million, and quarterly net loss was ¥718 million (versus net income of ¥205 million in the same period of the prior year). The full-year earnings forecast has also been revised, with net loss of ¥767 million (loss per share of ¥256.50) now projected. Operating income also deteriorated significantly in the core business, coming in at ¥96 million (down 68.3% year on year), making the establishment of recurrence-prevention measures and strengthened internal controls an urgent priority. This is the largest concern for investors.

In the nine months ended Q3, Technology Solutions Service sales were ¥2,063 million (down 4.2% year on year), and Content Marketing Service sales were ¥410 million (down 16.3% year on year), with both core businesses seeing declines in revenue. The decline in Technology Solutions Service was attributable to fewer deliveries of large-scale contracted development projects and volatility in advertising and paid-usage revenue share. Content Marketing Service was affected by a decrease in orders due to reduced advertising and marketing budgets, with the number of Hatena CMS operations at 148 (down 2 from the same period of the prior year). Operating expenses increased to ¥2,622 million (versus ¥2,591 million in the same period of the prior year), making sales growth essential for a recovery in profitability.

Expansion of revenue share from GigaViewer for Apps and acquisition of new customers for Mackerel APM functionality are at the core of medium-term growth, but both remain at the stage of showing only

Growth Strategy

Aiming for non-linear growth through three pillars: expanding revenue share from GigaViewer for Apps, deploying Mackerel's APM capabilities, and commercializing toitta

Promoting additional app-version implementation at media outlets that have already adopted the Web version. As of end-May 2026, the service was implemented at 28 services across 18 companies combining app and Web versions. The app version generates higher pageviews and sales than the Web version, and the company aims for substantial expansion of revenue share (advertising and monetization revenue) in addition to development and operation fees. "Comic Growth powered by GigaViewer" has also begun full-scale operation, expanding the scope of support.

Through the APM functionality officially released in May 2025, the company is promoting upselling to existing server monitoring customers and acquiring new customers. Support for OpenTelemetry has lowered barriers to adoption. Management has noted that "signs of recovery are beginning to appear overall," and sales expansion efforts continue.

For "toitta," the AI interview analysis SaaS officially released in October 2024, the company has newly launched the "toitta N1 Interview Research" service, providing one-stop support from research design through to reporting. Going forward, the company plans to further expand its scope of support, including AI-based interview execution, and pursue revenue growth through continued investment in personnel. Current revenue scale remains minor (total other services: ¥5 million).

In October 2024, the company joined as a co-operator (validator) of JOC. Following the completion of the IEO in December 2024, validation operations began, with JOC tokens acquired monthly as compensation. The company is considering Web3 services utilizing JOC that could help address social issues. Current revenue contribution remains minor (total other services: ¥5 million, up 29.9% year on year).
