Writer required for 20 short stories in Japanese (approx. 20,000 words total)

I am seeking a writer to produce 20 simple short stories in Japanese, approximately 1000 words each, for adult learners of Japanese. Stories are intended for A2-B1 level learners so you must have experience of working with Japanese students either as a teacher or producing learning materials. This is important in order to produce appropriately graded stories. The stories should use an N4 level of grammar and vocabulary, and N5 level kanji. Our goal with these stories is to help the student master Japanese grammar. For this reason, each story will have a higher than normal occurrences of a specific grammar point in Japanese (e.g. Japanese sentence structure, the particle wa vs ga, etc.). We will provide a list of grammar points that must be included and detailed language guidelines for the use of each one. You will need to create the stories with these grammar points in mind, and distribute them carefully throughout the texts. For example, one short story will focus on the particles wa and ga. So you will need to design a story that plans to use both of these particles frequently throughout so that the reader/learner is exposed to them and learns to notice the difference between them. However, the challenge at all times is to do this without distracting from the stories themselves. This is an important part of the project, so will require careful planning before starting to write. For this reason, you must have an excellent knowledge of Japanese grammar. I'm looking for someone with a proven track record of creative writing in different genres and be able to demonstrate the ability to grade writing for different levels of learner. In order to apply for this position, please... 1) Provide samples of previous creative writing (ideally fiction) 2) Describe your experience of writing graded material or working with Japanese students 3) Answer the following question: How would you approach the task of writing stories that are appropriate for N4 learners while also ensuring they are engaging and entertaining? I look forward to hearing from you!
