Tajima LLP is pleased to announce the successful closing of a significant trans-Pacific transaction in which our client, RTI Cable, transferred its interests in three major submarine cable systems — JGA North, JGA South, and SEA-US — to Lightstorm. This transaction represents a landmark deal in the submarine cable and telecommunications infrastructure sector, with assets spanning the Pacific Ocean connecting the United States, Japan, and Southeast Asia.

About the Transaction

The JGA North and JGA South cable systems connect Japan and Guam, forming a critical segment of trans-Pacific communications infrastructure. The SEA-US cable system connects Southeast Asia to the United States, providing high-capacity bandwidth across one of the world's most strategically important telecommunications corridors. Together, these systems represent significant infrastructure assets supporting international data transmission for telecommunications carriers, technology companies, and enterprise clients across the Asia-Pacific region.

Tajima LLP's Role

Our firm advised on legal aspects of the transaction, including matters related to the transfer of cable landing rights, regulatory considerations, and contractual arrangements governing the ongoing operation and maintenance of the cable systems. The transaction required coordination across multiple jurisdictions, including the United States, Japan, Guam, and Southeast Asian regulatory authorities.

Asia-Pacific Focus

This transaction reflects our firm's deep engagement with clients operating across the Asia-Pacific region. As cross-border transactions and disputes involving Asia-Pacific parties and assets continue to grow in complexity and volume, Tajima LLP is well-positioned to advise clients navigating the legal and regulatory landscape of this dynamic region. We bring both the substantive legal expertise and the cultural and commercial understanding that these matters require.

We congratulate our client on the successful closing of this transaction and look forward to continuing to support their legal needs.
