I bought the travel adapter for my Japan holiday, as it is recommended by the manufacturer for Japan. Unfortunately, it is so that there are two different plug systems are in Japan - and in Western and Zentralhonshu (Nagoya, Tokyo, ...) common connector type is not included in the set. I bought in Japan an additional adapter, which leads from a three-prong plug type contained on the usual spot bi-pin connector type. That went well - but looked funny (Device Cable -> Brennenstuhl-3-pin adapter -> Japanese 2-pin adapter). Without the additional adapters Brennenstuhl world Reisestecker would unfortunately have been completely useless for me.
