Attention, read specification (not suitable JAPAN)

This World Travel Adapter from SKROSS is certainly a multi-functional eye-catcher. Unfortunately, it is not compatible for outlets in Japan. For this country's best a plug for 2,99, - Buy the nearest electrical store. 99% of Japanese. Outlets are not grounded NEMA 1-15 (2-pin) connector and no 3-pole NEMA 5-15 plug like in the US, which should go with this adapter according to the manufacturer. Nevertheless, a good product, with regard to the other connector types. Unfortunately, not usable for my vacation.
