Answer:
Japan is an extremely advanced country, there are many reasons why japan acheived the title. Eg- the maglev train, this is the train being constructed in japan and is one of the fastest trains, it has never even been late by a second or two.... But I wont say japanese is the smartest country but it is definetley one of the most advanced counties in the world........besides every countries have theyre own pros and cons so who am i to judge?.....This one example itself shows how advanced and smart japanese in particular are.........hope this gives u a new insight about japan
