From Legal Counsel to IT Legal Specialists

MONOLITH LAW OFFICE advocates its advantages in “IT legal affairs, Internet legal affairs, and Business legal affairs”. We provide legal services to many companies with a focus on IT. We offer two main types of legal services.

One is a service based on the position of “General Counsel” or “Chief Legal Officer” for an IT company. Since the company’s primary business is IT-related, our firm is chosen for its ability to understand the client’s IT technology and business.

Second is to work as an “IT/Internet legal professional” for companies where IT is not their core business. Even though IT is not the core of businesses such as finance, real estate, and restaurants, they can no longer exist without IT and Internet. We provide support from a legal perspective to companies in their IT and Internet-related operations.

MONOLITH LAW OFFICE will work with you in various positions based on our high level of expertise to support the development of your company.

Handling cross-border legal matters

Handling cross-border legal matters

Managing cross-border legal matters in the IT and Internet sectors is our expertise. As globalization and cross-border activities gain significance, having proper legal support becomes crucial.

For instance, when a Japanese SaaS company expands into international markets, complying with local legal requirements and regulations becomes essential. Similarly, when receiving foreign investments, assistance in drafting and negotiating investment agreements and related legal documents is necessary. Conversely, for Japanese companies involved in overseas M&A or global expansion, understanding local laws and regulations is vital. Moreover, overcoming language and cultural barriers in cases like influencer marketing and inbound demand requires addressing local laws and contractual matters.

MONOLITH LAW OFFICE has strengthened its capabilities in cutting-edge legal fields to meet the demands of cross-border and globalization. By combining our team of lawyers with engineers and other professionals, we provide comprehensive support, leveraging technical knowledge and legal expertise, for our clients’ international expansion and global business endeavors.
