I am a Japanese attorney and a certified AWS engineer. I understand your technology stack, your contracts, and your compliance obligations — because I have worked on both sides of the table. Whether you are a startup, a SaaS company, or an enterprise navigating Japan's regulatory landscape, I speak your language.
About
I am Naoki Hoshino, a Japanese attorney (弁護士) registered with the 第二東京弁護士会 (Daini Tokyo Bar Association) and a certified AWS engineer. My background spans both legal practice and hands-on cloud infrastructure work.
Most technology companies in Japan struggle to find legal counsel who can read a system architecture diagram, understand what a data processing agreement actually means in practice, or advise on the legal implications of a specific API design. I can do all of that.
This practice is dedicated to IT companies, software developers, SaaS providers, and tech-forward enterprises operating in or entering Japan. I help you build legally sound products and businesses — without the translation overhead between legal and engineering.

Services
From startup formation to enterprise compliance — legal counsel that understands your stack
個人情報保護法対応
Japan's Act on the Protection of Personal Information (APPI) has significant implications for any company handling user data. I help you build compliant data practices from the ground up.
サイバーセキュリティ法務
When a security incident occurs, the legal response matters as much as the technical one. I advise on legal obligations, disclosure requirements, and liability management.
SaaS・クラウド契約
Generic contract templates do not work for SaaS. I draft and review agreements that reflect how your product actually works — uptime, data ownership, API usage, and all.
システム開発・委託契約
Poorly drafted development contracts are the source of most IT disputes in Japan. I help you define scope, IP ownership, and liability clearly before work begins.
スタートアップ法務
From incorporation to Series A, I provide practical legal support for tech startups in Japan — without the enterprise law firm price tag.
ソフトウェアの知的財産
Software copyright in Japan has nuances that general IP attorneys often miss. I advise on ownership, licensing, and enforcement with technical precision.
ITトラブル・訴訟
When IT projects go wrong, the disputes are technical and legal at the same time. I represent clients in system development disputes, data breach claims, and software licensing conflicts.
AI・新技術の法務
AI regulation in Japan is evolving rapidly. I help companies building or deploying AI systems understand their legal obligations and manage risk proactively.
Process
Reach out by email or the contact form. Describe your situation in as much technical detail as you like — I will understand it.
30 minutes online or by phone, free of charge. We discuss your situation and I give you an honest assessment.
I provide a clear scope of work and transparent fee estimate. No surprises.
Once the retainer agreement is signed, we get to work. I integrate with your team's workflow — Slack, email, or whatever works for you.
Contact
The first consultation is free — 30 minutes, no obligation. I consult in Japanese and English. Feel free to include technical context in your message. The more detail, the better.
