There is in any city in the world an area that really does not fit in, a place where whatever people try to do it will never work, and Osaki seems to me like one of this place.
Osaki feel like a place that nobody really cares, people pass right through it but never seem to stop for a rest. And why would they? There is nothing interesting there to see, no big mall or department store, just barely the minimum with some king of business center that seems desperately empty.
Walk away from Osaki in Direction to some of Sony’s R&D buildings and you will only find bankrupt business or closed warehouse that have been abandoned just recently (a few years back).
Still if you have time and ever wanted to see another face of Japanese Business life, go and have a walk around Osaki and after a few minutes walk you will start to wonder if you are still in Tokyo or in these ghost town that are now coming more and more common in some regions of Japan.
