Hello Anders, There are a few useful expressions used in Japanese to begin a conclusion paragraph depending on what you want to say after such as 結局；以上のように；結論として；この体験を通して or even 最後に. The end will also depend on what the content of your conclusion is. For example if you are stating your opinion you'd want to end with　～ほうがいい・～べきだ・～（だ）と思う。 The Japanese are also big on rhetorical questions to end speeches or essays. As if to leave an idea hanging as food for thought. Something like "Does this not prove the unfairness of gender wage gap?" or "Can it not be said that this is the result of the educational differences between the generations?" When doing that you basically add the question to the very end of your conclusion paragraph, after you have already closed all your ideas. It can be done by using ～のではないだろうか。・～と言えるのではないだろうか for example. I am only a student in Japan myself but if you have any more specific questions let me know, I might be able to help. Good Luck there!
