The research plan can be written in the order of "research topic+research purpose+research content+research method+preparation or progress+references". Of course, different people write differently, and the composition of the article has no certain rules, but the research theme, research purpose, content and research methods are necessary.
The language requirements of Japanese research plan and thesis are the same, so we should use simplified type, avoid using honorific type, and even less use honorific words. When mentioning a person's name, you can't add "さん" or "sir", you must call him by his first name. In addition, there is a big gap between written and spoken Japanese, just like in Chinese, people say "I and you and others" less, and say "I and you and others" more, with different words.
It may be necessary to investigate the problems and direction of this major more specifically.
