What founders should understand before fundraising with J-KISS

Hello, this is Legal Agent.

Most J-KISS consultations arrive after an investor has already proposed terms and the founder wants to close quickly. The contract itself is short, so people assume review will be quick too, but the time actually goes into what sits outside the contract: the cap table and the company's relationship with existing shareholders. This article lists what to check before signing, in the order we actually work through it.

J-KISS issues a paid stock acquisition right designed to convert into shares once a triggering event, typically a future financing round, occurs, rather than issuing common or preferred shares immediately. What that conversion actually does depends on the exercise conditions and the type and number of shares set in the issuance terms. In Japan, the template published by Coral Capital is the most widely referenced version, and METI's guidance on convertible instruments cites it as a leading form of convertible equity.

J-KISS is sometimes described as a simple way to raise money, which is true up to a point. A short contract does not mean a light decision, though. Ownership stays invisible at issuance and then converts all at once at the next round, so a founder who assumes "no shares issued yet means no dilution yet" can be surprised by how much a Series A term sheet actually costs in founder ownership.

Self-check before signing

• have you divided the investment amount by the post-money cap to get a floor for that investor's eventual stake?
• if issuing J-KISS more than once, do you have a policy for how each round's cap is set relative to the others?
• if the conversion deadline arrives without a Series A, do you know who you will be negotiating with and about what?
• have you checked notice or consent obligations toward existing shareholders under prior contracts, such as advance notice before a new issuance?
• have you planned for the paperwork triggered at Series A conversion: exercise procedures, consents, and registration?

The misconception that J-KISS defers valuation

J-KISS is often described as fundraising without deciding today's valuation, which has some truth. An early-stage company's revenue, users and product are still moving targets, making it hard to fix an issue price for common or preferred shares, so waiting until Series A to price the round has real practical logic. But this understanding alone is dangerous. J-KISS almost always sets a valuation cap, which fixes the ceiling valuation used at future conversion. Even though the final issue price is not decided today, the formula used to calculate it later is. If Series A investors value the company generously, J-KISS investors may still convert at a materially better price than they do, using the cap as a floor for how much better. It is more accurate to think of J-KISS as agreeing today's formula for tomorrow's share issuance than as deferring the valuation conversation. Skimming past the cap, discount and exit terms on the assumption that J-KISS is simpler than a preferred round can force an unwelcome adjustment at Series A.

The valuation cap drives future dilution

The valuation cap is the first term to examine: the lower it is, the more shares J-KISS investors are likely to receive on conversion. J-KISS 2.0 uses a post-money cap, whose practical advantage is that dividing the investment amount by the cap gives a rough floor for that investor's eventual stake. This is more useful than the pre-money/post-money label itself, since it puts a number on what percentage an investor is likely to end up with.

It is easy to look only at the cap number and decide it is acceptable. But founder dilution only becomes visible once the next round's raise amount, the number of preferred shares issued, the option pool, any additional J-KISS rounds, and existing shareholders' stakes are all modelled together, under scenarios where the Series A valuation lands both above and below the cap. Looking at only one scenario is a common blind spot. Where an additional J-KISS or bridge round precedes Series A, deciding whether the second cap matches the first or is priced up compounds the complexity of the eventual conversion math, and expanding an option pool at the same time as J-KISS conversion often shrinks founder ownership by more than expected. The cap is simultaneously a term about how much can be raised today and about who owns how much after the next round. Keeping both in view changes how the negotiation looks.

The discount, read together with the cap

A discount lets J-KISS investors convert at a percentage below the price paid by new investors in a qualified financing. A 20% discount, for example, means buying in at 20% below the Series A price, rewarding investors for taking risk earlier. The discount only makes sense read against the cap: where the cap produces the lower price, the cap applies; where the Series A valuation does not reach the cap, the discount becomes the effective floor. What is worth modelling is not the discount rate itself but which of the two terms is more likely to bind. Counterintuitively, the better the company performs, the harder the low cap bites, since a strong Series A valuation is exactly when the cap holds down the conversion price. That is good for early believers, but it is also a structure where success itself drives more dilution for founders. A discount alone, with no cap, tracks the Series A price and does not fix a ceiling the way a cap does. Which structure suits a given company depends on the investor relationship, amount raised and bargaining strength, and it is not unusual to see the discount function as the sole formula for a qualified-financing conversion with the cap retained only as a reference price for the deadline or an M&A, or the reverse, an angel round with the discount set to 0%. Where multiple investors come in with different caps or discounts at different times, that alone is not necessarily improper, but the company should be able to explain the difference, whether by timing, risk taken, or support provided, before Series A due diligence asks the question.

Conversion mechanics are tied to the Series A design

What matters most is what triggers conversion, into what class of shares, and by what formula. The trigger is typically a financing above a stated size. If the definition of the triggering round is too broad, conversion happens earlier than expected; if too narrow, a raise the company considers its next round may not count as a conversion event under the J-KISS terms. This matters because real financings are not always a clean "Series A" of preferred shares: a small common-share raise, an additional J-KISS, bridge financing or a follow-on from an existing investor can all raise the question.

The class of shares received on conversion matters just as much. Where Series A issues preferred shares, whether J-KISS investors receive the same class, a different class, or common shares changes the relative rights among investors, since preferred shares typically carry liquidation preference, deemed-liquidation and voting terms that common shares do not. Keeping the cap table simple in the early rounds tends to make later rounds easier to manage. Conversion is also not automatic the moment Series A is agreed: exercise notices or the company's redemption procedure, consents to amend the terms, a registration change, and updates to the register of rights and the shareholder register all run in parallel with the Series A closing, and a company that has already issued preferred shares may need more than one class meeting. This is worth planning for at issuance rather than during the Series A crunch.

The conversion deadline, and what happens without one

Where no qualified financing occurs within a stated period, METI's guidance describes a design letting investors request conversion to common shares after 18 months; the template allows exercise, once the deadline passes without a qualified financing, on approval by holders of a majority of the aggregate issue price. What is easy to overlook is that nothing converts automatically at the deadline. Investors and the company negotiate, based on where the company actually stands, whether to convert to common shares, extend the deadline, or change the terms. We have seen deals where, as the deadline approached, the parties signed a short agreement simply moving the date. The deadline functions less as a hard stop than as the day negotiation begins, so what matters at issuance is not just the number of months but who holds a majority of the aggregate issue price, how easy an extension will be to negotiate with them, and whether the underlying business plan can tolerate delay in reaching Series A.

Existing shareholders: procedure and buy-in

Issuing J-KISS still requires the statutory steps for a rights offering under the Companies Act, including shareholder or board approval of the terms depending on whether the company is a public company, and a class meeting where applicable, but the legal minimum is rarely enough in practice. Where a company already has investors, past investment or shareholder agreements often include prior-consent requirements, pro-rata rights or issuance restrictions, so treating J-KISS as "not shares, so those contracts don't apply" is a mistake worth avoiding. Skipping notice to existing investors can also become a representation-and-warranty problem toward the new J-KISS investor, since the template typically has the company represent that it is not in material breach of its existing contracts. A missed notice obligation under an old VC agreement can therefore flow through to a breach claim from the new investor. Checking notice clauses in existing contracts should be the very first thing done when planning a raise, precisely because it is the first thing skipped when a closing is rushed.

What surfaces once J-KISS connects to a preferred round

Whether J-KISS terms actually suited the company becomes visible at Series A, when a new investor proposes a term sheet and negotiates preferred terms, the investment agreement and any founder lock-up. How the existing J-KISS converts shapes how the Series A investor reads the cap table: a large converted stake raises questions about whether enough founder ownership and option pool remain, and individually granted rights such as information or pro-rata rights complicate reconciling J-KISS and Series A investors' rights. Side letters deserve particular scrutiny, since a standard-looking main J-KISS agreement can still carry additional rights granted through side letters that resurface during Series A diligence. Rather than assuming the standard template is automatically fine, founders should inventory every signed agreement, amendment and shareholder consent before Series A. A cap table showing the post-conversion ownership, paired with a clear account of contractual rights, materially eases that negotiation.

Exit before conversion

Where a company is acquired before converting, the economic treatment of J-KISS investors matters even for founders aiming at an IPO, since an early sale can become the realistic path depending on the business and fundraising environment. Where the terms return a multiple of the investment amount on an exit, that multiple and its priority directly affect what founders and existing shareholders keep. Heavier priority for J-KISS investors can leave little for common shareholders where the sale price is not large, and while that can be reasonable investor protection, how much of it to accept should be checked against realistic exit scenarios.

It is also worth checking how broadly "change of control" is defined, since the template's version can extend beyond a share sale or merger to a sale of substantially all assets, dissolution, liquidation, or even an IPO, and in some cases a J-KISS investor's prior consent has been required under the investment agreement even for founders moving shares among themselves. J-KISS does not stop mattering once issued; it continues to have a say in later share movements. Once preferred shares exist, an M&A pulls J-KISS-derived shares, Series A preferred shares and stock options together, with deemed-liquidation and distribution terms overlapping, so the cap structure gets complicated quickly. J-KISS is both a financing tool for reaching the next round and the economic terms that apply if that round never happens.

What founders should prepare before issuing

A contract review alone is not enough. Build a cap table that reflects post-conversion outcomes, including issued shares, founder and existing shareholder stakes, the option pool, the current raise, the cap, the discount, and an assumed next-round valuation and amount, across multiple scenarios, taking care over details such as excluding treasury shares and treasury rights, keeping the option pool and issued options consistent, and recalculating for any J-KISS converting at a discount. Second, inventory agreements and consents with existing shareholders, since this connects directly to representations made to the new investor and belongs at the very start of the fundraising timeline. Third, model the expected next round: whether Series A will issue preferred shares, the expected raise, milestones to reach by then, and how much the option pool will grow. This alone makes judging whether today's J-KISS terms suit the company much easier. Fourth, keep a short memo on information rights and investor relations: who receives monthly reporting or board materials, how often investor meetings happen, how much pro-rata right will be granted at the next round, and whether side letters will be used. Where individual investors are involved, check Japan's angel-tax-incentive documentation separately, since eligibility is not automatic at the time of investment even where a paid stock acquisition right acquired on or after April 1, 2024 may later qualify. Finally, keep the issuance paperwork itself, including shareholder resolutions, allotment notices and registration documents, in order, since gaps here cost time during Series A diligence.

Whether it closes matters less than whether it connects

Raising through J-KISS matters because it buys time: to build the product, hire, test customer acquisition and reach the next round's milestones. But the decision is not only whether money comes in on these terms. It is whether enough founder ownership survives Series A at these terms, whether the option pool still supports key hires, whether existing shareholders are satisfied, whether J-KISS and Series A investor rights conflict, whether a delayed business plan is punished by the conversion deadline, and whether an early M&A's economics can be explained. Working through these questions before signing, rather than after, is what determines whether J-KISS was the right tool for this company.
