Soon
In A Few Days, Coming Days
noun
The near day is a day coming very soon. It's a day coming in a few days or in the coming days. In other words, you wouldn't use this word for something that's going to happen in a few minutes, or a few months.
This is a relatively formal word that is commonly used in professional or official contexts.
This is a jukugo word, which usually means on'yomi readings from the kanji. Since 日 has two on'yomi readings, here's a mnemonic to help you remember which one to use:
Soon, the place where you live will have two kings. Gee, two (きんじつ) of them? Yep, yours is the first country ever to have two kings.
