Growing up means putting away your toys. At least that's the accepted view. But in truth, adults don't forsake toys -- we just buy more expensive and interesting ones.

Those seeking to indulge themselves will find a land of opportunity in Akihabara, the Tokyo suburb that is famed as the nation's No. 1 marketplace for electronic goods.

Tourists love Akihabara -- it's an essential stopping place for most visitors to Tokyo -- and Akihabara loves them, as is shown by the plethora of duty-free shops in the area, including major players like LAOX, Nishikawa, Nakaura, Takarada Musen, Akky International and Ishimaru Denki.
