Hi all! I just bought a jpn set while travelling in Japan. Quick question: is it I have to set up an account that is set in Japan in order to access the eshop (initial confoguration Doesnt allow me to set it at Singapore) and I do not need to buy a transformer for the wall plug, as a travel adapter will suffice. Will it affect the performance in terms of charging. Lastly, are there any must owned games here in Japan (looking at Japan only titles) and accessories. I only bought the mario Kart game
