Pulling numbers from your you know what again?

Japan could easily get 0.5% more (or more given this is just base rate) on this loan servicing within its own domestic economy and right away. So offering a massive grace period of 10 years AND a 30 year window AND fixed 1% interest rate is a pretty huge ODA (and hence why it gets put as ODA in first place) that amounts to effectively some level of billions when all is said and done. The exact number of that will only be available after that window has elapsed by checking the opportunity cost integral.

For once I semi agree with you.
Actually the interest rate is a paltry 0.01%. With the 10 year grace period and then repayment over the next 30 years this is a very good deal for BD. Inflation will so eat away at the principal amount that it is only technically a loan and is in practice more a grant.
Yep, Japan is by far the best development partner of BD and will hand out around 2 billion US dollars a year of these ultra low-interest loans over the next 5 years. Most of Dhaka's infrastructure over the next 15-20 years will be built using JICA loans.
It is true that Japan is getting some benefits out of this by getting work for it's companies but this is on the whole Japan genuinely wanting to help a poor country like BD out. I am sure that BD will always remember the generosity that Japan has shown it.
