It is NOT in English

It is extremely frustrating (much more than just disappointing) for an app this price to have everything in Japanese, while it was supposed to be meant for travellers and foreigners - who do not read Japanese script.
Actually menus can be in either Japanese, English or Korean, but the maps and all indications are in Japanese only, including metro and train stations, POI and everything else!
Then it becomes useless for someone like me - I cannot even ask it to take me to the Tokyo Station, the Tokyo Dome, Tokyo Tower, Yasukuni Jinja... (very famous Tokyo POI) as I would have to write it in Japanese!
The free maps coming with the iphone are just so much better - it is not only in English but any Language you want, and the navi device allows you abc type in. Ok, no 3D, thats all.
I wasted my money, do not waste yours.
