On October 24, 2012, Collabrium Japan Acquisition Corporation (the “Company”) consummated the initial public offering (“IPO”) of 4,000,000 of its units (“Units”).  Each Unit consisted of one ordinary share, no par value per share (“Ordinary Share”), and one Warrant (“Warrant”), to purchase one Ordinary Share at an exercise price of $11.50 per share.  Simultaneously with the consummation of the IPO, the Company consummated the private placement (“Private Placement”) of 3,600,000 warrants (“Private Placement Warrants”) at a price of $0.75 per Private Placement Warrant, generating total proceeds of $2,700,000.

On November 29, 2012, the Company consummated the closing of the sale of 200,000 Units which were sold subject to the underwriter’s over-allotment option.  The underwriter has indicated to the Company that it will not be exercising the remaining portion of the over-allotment option.  As a result, the Company’s initial shareholders will be required to forfeit an aggregate of 133,333 ordinary shares issued to them prior to the IPO.

The 4,200,000 Units sold in the IPO, including the 200,000 Units sold subject to the over-allotment option, were sold at an offering price of $10.00 per Unit, generating total gross proceeds of $42,000,000.  Of the gross proceeds of the IPO and Private Placement, $43,370,000 (or approximately $10.33 per share) was placed in trust.

A copy of the press release issued by the Company announcing the consummation of the sale of the Units subject to the over-allotment option is included as Exhibit  99.1 to this Report of Foreign Private Issuer on Form 6-K.
