Software for venture capital funds in Japan
One platform for high-volume deal flow, founder scoring, IC memos, portfolio monitoring and LP reporting, priced in JPY.
Reuben AI is used by venture capital teams across multiple jurisdictions. This page summarises how the platform fits the regulatory and structural context that venture capital teams in Japan typically operate in.
A venture manager runs a high-volume top of funnel against a small number of cheques, then supports those positions through many rounds of dilution. The operating problem is keeping deal flow, ownership and investor reporting consistent while the portfolio compounds in complexity.
Regulatory context in Japan
The primary financial services regulator is FSA (Financial Services Agency).
Japanese private funds commonly use Investment Limited Partnerships (LPS), GK-TK structures, TMKs or Investment Trusts, with the manager registered under the Financial Instruments and Exchange Act as Type II Financial Instruments Business or Investment Management Business and supervised by the FSA.
Common fund structures we see
- Investment Limited Partnership (LPS) under the Limited Partnership Act for Investment (Act No. 90 of 1998)
- Godo Kaisha and Tokumei Kumiai (GK-TK) structure under the Companies Act and the Commercial Code
- Tokutei Mokuteki Kaisha (TMK) under the Act on Securitisation of Assets
- Investment Trust (Toshin) under the Act on Investment Trusts and Investment Corporations
Reuben AI is structure-agnostic. It stores investment, LP and portfolio data in a shared model that maps cleanly onto each of the vehicle wrappers above. It is not a legal, tax or regulatory advice tool. Fund formation and structure decisions should be taken with qualified local counsel.
In-market depth for Japan
Japan is a priority market. Reuben AI is used by GPs and institutional LPs across Tokyo, with fund workflows aligned to FSA-registered managers and QII-eligible investor pools.
Regulatory depth
- Financial Instruments and Exchange Act (FIEA): registration regimes for Type II Financial Instruments Business and Investment Management Business.
- FIEA Article 63: Specially Permitted Businesses for Qualified Institutional Investors (QII), the common route for domestic private funds raising from QIIs.
- Limited Partnership Act for Investment (Act No. 90 of 1998): the LPS vehicle used for onshore private capital funds.
Vehicles institutional teams use here
Japanese institutional teams typically operate through Investment Limited Partnerships (LPS) under Act No. 90 of 1998, GK-TK structures for asset-holding, or TMK vehicles for real estate. Reuben AI stores these as first-class vehicle types alongside their partner and investor registers.
Reporting and currency norms
Base currency is JPY, with USD reporting overlays common for cross-border LPs. Quarterly LP reporting is the norm; TMK and REIT structures follow additional statutory reporting cadences.
Operating context
Support and product hours cover JST business hours. LP-pack exports can be prepared in bilingual (JA/EN) format. Data isolation is per-workspace with regional cloud residency available on request.

How venture capital teams in Japan actually operate
Venture teams see far more opportunities than they can act on, and most of the value of a pipeline is in the record of what was passed on and why. Firms that cannot recall their own history end up re-diligencing companies they already know, and end up unable to explain a decision to their investment committee months later.
On the portfolio side, ownership is the number that matters and the number most often wrong. Each priced round, safe conversion, option pool refresh and secondary sale changes it. When the cap table lives in a spreadsheet, fund-level ownership becomes an estimate. Reuben AI recomputes ownership from the round events themselves, so the position and the report agree.
The recurring work Reuben AI carries
Pipeline with memory
Every company seen, the decision taken and the reasoning retained, so a returning founder meets a firm that remembers them.
Diligence to memo
Documents, references and analysis assembled into an investment committee memo drawn from the underlying record rather than retyped.
Ownership through dilution
Rounds, conversions, pool refreshes and secondaries applied so that ownership is computed, not maintained.
Investor reporting
Capital account, valuation and portfolio commentary produced from the same record used to manage the fund.
Local structuring, tax and regulatory advice remains with the fund's counsel and administrator. Reuben AI is software and is not registered with FSA (Financial Services Agency).
Common questions
Does Reuben AI replace the venture CRM?
Yes for most teams. Pipeline, diligence, portfolio and investor reporting sit on one record, which is what removes the reconciliation work between a CRM and the fund's actual books.
How is ownership kept accurate over many rounds?
By storing the round events and recomputing ownership from them, rather than storing a percentage that has to be manually updated every time the cap table moves.
Can the fund report to investors without an administrator?
Reporting is generated from the fund record. Whether an administrator signs off on those figures remains the manager's choice and their audit arrangement.
