Kabunushi Memo
A monthly briefing service for Japanese retail investors that translates shareholder-meeting news, dividend notices and earnings into plain-language action memos.
Long-term Japanese retail shareholders who hold dividend stocks and want minimal noise
- Plain-language monthly memo per held stock covering dividend, buyback and earnings signals

- Tax-relevant flagging of dividend changes above thresholds
- Side-by-side comparison of 3-5 similar Japanese peers in the same sub-sector
With BS11's quarterly progress rate flagged across Japanese investor forums, retail holders are anxious about quality-of-earnings rather than just top-line numbers.
Multiple active Substack newsletters already serve this exact audience (DividendJapan.com, Kabu Japan, Japan Market Insights) each with 'hundreds of subscribers,' confirming demand but also that the audience is fragmented and modest in size; the BS11 'why-now' trigger was not corroborated in search results.DividendJapan.com | Substack ↗Kabu Japan | Substack ↗
Crowded: at least 3 direct-competitor Substack newsletters (DividendJapan.com, Kabu Japan, Japan Market Insights) plus institutional players (Minsetsu, QUICK Data Factory) covering shareholder briefings and earnings transcripts for Japan.Best Japanese Stock Newsletters & Analysis (2026) | RhinoInvestory ↗Transcripts of earnings meetings SCRIPTS Asia - QUICK Data Factory ↗
Substack paid-subscription model is proven for Japan-focused newsletters, but Japanese retail investors are notoriously price-sensitive and DividendJapan.com explicitly offers free updates — willingness to pay a premium for a 'plain-language memo' wrapper is unproven.About - DividendJapan.com ↗Japan Market Insights | Substack ↗
Dividend and shareholder-meeting information is evergreen and tied to long-term holding cycles; the audience self-selects for stickiness, and the underlying companies (BS11, dividend payers) operate in stable retail/consumer sectors.
Easily launched as a Substack publication — core work is Japanese-language news curation and translation into plain-language summaries; low tooling cost, no regulatory hurdle, but requires fluent JP analyst or reliable LLM translation pipeline.
