This statics was released on 19th of March.  The whole country sales of department stores is also released at the same day.  So I believe it is much easier to understand the current status when we use this statics together.

The foreigner sales in whole country sales of department indicates the high growth which extends 15 billion yen(+235%)  The sales of Tokyo area is 117.4 billion yen, so it is obvious that contribution of the foreigner sales is high for expansion of the sales.

On the other hand, there are also a lot of cities which recorded a negative growth in local cities.

We can conclude that the property value of the Japanese cities is developing polarized. A fair wind is blowing about the property price in commercial area in Tokyo.  This impact will lead to improvement of the renting supply and demand of the housing market in Tokyo.
