“We now get review results back in roughly one business day. The cost is about JPY 10,000 per contract review, which feels like one-third to one-quarter of what we paid before. Both the turnaround and the price have been a great help to us.”

FAQ

Frequently asked questions

Can we consult you from incorporation onward?

Yes. We support you stage by stage, from articles and governance structure around incorporation, founders' agreements, shareholder structure and contract templates through to preparing for a seed round.

Is a retainer required? What does it cost?

No retainer is required. Matter-based work such as financing document review and stock option grants is a fixed fee that includes revisions, set before we start. If you want ongoing advice, the monthly retainer starts at JPY 10,000, and you can combine it with spot work.

How fast do you respond?

We answer within one business day as a rule. When a financing closing or product launch deadline is close, we present a schedule worked back from that date.

Do you also act for investors?

Yes. We support VCs, CVCs, corporate investors and other investors in contract negotiations. Drawing on practice on both the issuer and investor side, we frame the key negotiation points.

Can the same firm handle IPO preparation and M&A?

Yes. We stay with you through IPO preparation, post-IPO corporate legal work, and legal due diligence and SPA negotiations when you sell.

Is the review done by AI alone?

No. Our AI Agent is used for issue spotting, drafting and drawing on past know-how; attorneys make the final legal judgment and write the comments.
