What makes us unique

Connecting Japan with ASEAN –
Efficient solutions in a unified legal platform

The amazing surge in ASEAN economic development has brought about an unexpected influx of Japanese companies to the region. One of the biggest misconceptions from foreigners conducting business in Southeast Asia is that they tend to put all ASEAN countries under a single umbrella. Nothing could be further from the truth. The laws of Thailand, for example, are not even remotely similar to the laws of Singapore or Brunei.
Each of the ASEAN countries has its own perspective on fair play, justice, and the relationship of individuals or corporations with regard to taxation, immigration, or labor. Navigating these laws is a job for experts in these fields. We eliminate the need for our clients to contract with legal network in each ASEAN country; all of our clients’ needs are solved through one legal window.
