Begin with creating a basic outline. Decide on the setting, whether it's a modern - day city, a fantasy world with Japanese - inspired elements, or something else. Then, think about the rules of summoning in your story. Are there incantations, special items required? Once you have these elements in place, start writing the story, focusing on building the relationship between the summoner and the summoned entity, and how their interaction drives the plot forward.
First, do research on Japanese culture, like their mythology, historical figures, and traditional values. This will give you a rich pool of ideas to draw from.
Think about the concept of summoning. What would be the reason for summoning a Japanese element? Is it for help, for knowledge, or something else? Develop your characters around this idea. For example, if it's a modern - day student summoning an ancient Japanese scholar, how would their personalities clash or complement each other? Also, read other fanfictions in the genre to get a feel for the style and common tropes.
