Japan is a country that wants to be friends with other countries and help them out when they need it. So they made a group of people in charge of giving money and other things to other countries. We call this group of people "foreign aid institutions."
These institutions have a big job to do because they have to think about which countries need help the most and figure out how to give them the right things. They talk to a lot of people in the other countries to find out what they need, like food or medicine or help building houses.
One of the things Japan's foreign aid institutions do is give money to other countries. This money can be used to buy things the country needs or to help the people who live there. Sometimes the money is used to build things like schools or hospitals.
Another thing the institutions do is send people to the other countries to help out. These people are called "experts" because they know a lot about things like farming or engineering. They teach people in the other countries how to do things better so that they can take care of themselves in the future.
Overall, Japan's foreign aid institutions are really important because they help countries who don't have as much money or resources as Japan. They want to make sure everyone has a fair chance at a good life.
