Comparison/contrast essay??

Well I have written a comparison and contrast essay(the topic is about two places, I chose Bhutan and Japan), and I'm not sure about its organization and especially the content, could you please check it for me?
Under the surface of contradiction lies the similarity. Sometimes things which appear to be different have something in common. Japan and Bhutan are a good example for that. When you compare these two countries they seem dramatically different, but they have some things in common.
Japan and Bhutan are remarkably different. Starting with the capital city of both countries. Tokyo is the capital city of Japan, yet Thimpu is the one of Bhutan. In addition, it is well known that Japan heads the list of the most development countries especially in the technological domain. A recent invention made by Japanese, consists of a robot capable of not only playing Ping-Pong game but also defeating its advancer.However, Bhutan is having much difficulties to keep-up with the unstoppable, technological development which is mainly caused by its harsh geographical location. Japan does not only heads the list of the most developinng countries, but also the one of the most populated countries, unlike Bhutan which has a really low percentage concerning population.
The common points between the two countries can be showed in their continent, surface and climate. Both countries are located in Asia. Japan is located in the Eastern part and Bhutan in the Southern one. Japan and Bhutan lay on a small surface. The tropical climate is the defining climate for both countries.
To sum up, despite the lack of similarities between the two countries, it is due to their differences that each country is special in its own way.
