At Fortuna Admissions, we are familiar with IUJ, Keio and McGill Japan (none of which you mentioned) but unfortunately we don't know too much about the Japanese MBA programs you mentioned, to be honest.
However I have a suggestion for you to contact Vince Ricci, an MBA admissions consultant based in Japan. Though he works primarily with candidates applying to US schools he might have some local knowledge. You can reach him at Vince@VincePrep.com
If you wanted to attend one of the top 10 b-schools, you could consider INSEAD or LBS - particularly INSEAD as you could spend your entire year on their Singapore campus where a lot of East Asian recruiters end up. But as you said, it might make more sense to study among the culture you want to work for in the future (though not sure if you are looking for all the courses to be in English or in Japanese or both).
Generally people apply to 3-5 schools as you obviously don't want to put all your eggs in one basket. Plus as you said, the application fees can add up and can range ($150-500 ish). Generally round 1 is the best (but this is normally the case for US schools - INSEAD and LBS still have many slots in the final rounds - the only thing affected is that you won't have as many options for scholarships if you wait until round 3). For more information read a post of ours on ideal timing re: round 1 and 2 http://fortunaadmissions.com/fortunas-m ... nd-1-vs-2/
OR more about round 3 http://fortunaadmissions.com/what-are-m ... n-round-3/
An MBA is very much transferable across the globe however you have to think about where recruiters will go and where strong alumni networks are based. If you are interested in only working in the US, it might make more sense to end up at a US school. If you know you want to end up in Japan, your chances of getting a job in Japan post your MBA, are probably higher as most of the recruiters will be Japanese based. Or at INSEAD or LBS, as they are more of an international school there are a lot more international opportunities.
Some schools allow you to defer no-problem but others aren't as flexible and you have to have a pretty darn good reason of why you are asking to defer. So you'll have to look into your specific schools to get more info on this - just to be on the safe side.
Hopefully this all helps.
