Again, in regards to Roppongi, I’m another of the ‘no-way!’ brigade.

You can walk to Roppongi from Azabu Juban, but it’s miles away in other respects.

One of the reasons that Azabu Juban and Hiroo have their fair share of expats is the amount of Embassies and Consulates in the area. One of the reasons that this concentration came about is because this part of Tokyo has particularly solid foundations and has traditionally remained less prone to earthquake damage. This also made it a sound choice for affluent Tokyoites (there are a good few members of the Japanese Aristocracy in the ‘Juban.)

As an address, Minami Azabu seems to provoke the same kind of reaction from Japanese people as somewhere like Chelsea or Fullham would from Brits. Roppongi is more like Leicester Square… it might be alright for a night out, but you wouldn’t want to live there.

Hiroo has a lovely park and very good stores for International foods, but I'm more familiar with Azabu Juban as that's where my husband's family home is. (He used to play in the park in Hiroo as a child... and he taught me how to make sailing boats out of bamboo leaves there)
