Even between Narita and Tokyo city centre I was blown away by the countryside. Strange that "The last Samurai" was filmed in NZ.
The Japanese with their large population and lack of arable land and raw materials have, for many years, faced the problem that they need to import much of its produce and raw materials. This is the reason for their aggression, be it martial agression as in the case of the second world war or, as is the case now, aggressively exporting their products.*
Now before any Nipponophiles attack me I stated earlier that I admire them. Anybody who can move from a feudel to industrialised society within 50 years earns my respect.
*There are many parallels between the UK and Japan in this regard.
