Collabrium Japan Acquisition Corp (NASDAQ: JACQ) was a blank check company formed to pursue an acquisition or business combination with companies operating in or connected to Japan, reflecting a niche geographic focus uncommon among U.S.-listed SPACs at the time. Sponsored by Collabrium LLC, the company completed its initial public offering in 2013 and registered with the SEC as a foreign private issuer, filing periodic disclosures on Form 6-K rather than the domestic 10-Q and 10-K cycle. Its November 2013 6-K filing was part of the routine reporting cadence during its search for a target in the Japanese market.
