Architecture

Hello Arawin,
Spain: They have not just a lot history in architecture, but their contemporary architects are top of the tops. Their offices and schools are very technichal, very focused in the building process. I would recommend it if you want to learn about building.
England: They have some of the top schools, probably more than any other country. The Architectural Association is probably the school the the most renowned graduates (from Rem Koolhaas to Richard Rogers). Very futuristic. The Bartlett School of Design is also a very progressive school, it was directed by Peter Cool.
Japan: their school is very clean, clear, simple and competitive. I think their style of design is perfectly aligned for the technology and construction methods of their country. I don't think their philosophy, working ethics and design philosophy could work 100% in other countries, but that's precisely the power of their work.
Netherlands: Very radicals. Focused on innovation, fragmentation, information, data, program (or lack of program). Very funky schools. They also understand the landscape like no one else in the world. Probably this would be my personal choice to study a graduate program.
US: Even though the US is the country with the most prestigious universities in the world, I don't think their architectural faculties or practices are that innovative. Some of they are, but I think architecture in the US is very traditional and not that innovative. There's the Science-Arch but it's too futuristic for me. Probably something in any, but other than that, I wouldn't take the time to study architecture in the us.
Germany: Very technical.
