When I first came up with the idea, whaling, I did not have many ideas to write about. I put whaling center and wrote ideas what I think about as Japanese. I know other countries are against whaling and I wrote the reasons why they are against. Then I thought about why Japan is a pro-whaling country. I found out the history of whaling in Japan and food culture. When I focused on the history, I found out that other countries also have whaling tradition. I have got a question; why is only Japan criticized? Also I looked for other ideas from food culture such as Japanese food situation.
