Hi user35923, thanks for your first question on Japanese Language Stack Exchange. If possible, please could you indicate your research effort in your question? This makes it easier for other members of the community to answer your question in a way that is helpful to you. It also makes it less of a translation question, which is off-topic for the site (see: https://japanese.stackexchange.com/help/on-topic). Thank you!
