Making it a loan will also allow for larger sums to be spent.
Japan's ODA has been mainly done in Asia, and to me it looks like its philosophy is producing results.
You clearly don't understand the Japanese. If anyone is to be embarrassed, it is the Nigerians promising to pay and then failing to. Accepting money from the Bill Gates foundation is more shameful. Japanese do not beg.

"if I were a citizen of Japan I would be embarrassed that the money was not just gifted as part of a foreign aid program."
And my reply is, no, Japanese citizens would not be at all embarrassed about this. Japanese, culturally, do not give hand outs. Giving out money to beggars is not only something they don't do, but something they don't approve of others doing. It's the moral equivalent to feeding the stray cats in the neighborhood. You aren't helping the cats. You are making the cats dependent on handouts and attracting more of them.
Likewise, the Japanese do not expect handouts either. Japanese do not beg. They are too proud to do it, and they know they will be shamed if they were to try anyway.
I am pointing out to Consultant32452 that if he expects the Japanese to be embarrassed about their lack of giving to Nigeria in this case, he is mistaken. Quite the opposite. What Nigeria has done would be considered shameful shirking in Japan.
Presumably, Nigeria agreed to the terms, so I don't see the issue.
