In 1990, Japanese founders established ILS to guide Japanese corporations entering the United States (and vice versa) with audit, tax, and financial expertise.
Over three decades, we have evolved into a full-spectrum advisory firm, expanding into Japan, India, and strategic hubs worldwide. Our clients now include multinational, mid-market leaders, and high-growth companies operating across borders.
