One common plot twist could be that in Japan, Harry discovers a whole new type of magic that is unique to Japanese wizarding culture. For example, there might be magical creatures that are native only to Japan, like the Kappa, and Harry has to learn how to interact with them. Another plot twist could be related to the Hogwarts houses. In the Japanese setting, the sorting hat might have different criteria or might even introduce a new house that combines the values of the existing ones, and Harry gets sorted into this new house which changes his whole Hogwarts experience.
Harry might adapt by learning the language first. Since Japanese is different from English, he'd have to study it to communicate with his classmates and teachers. He may also adapt to the different school uniforms. Japanese wizarding schools might have more traditional - looking uniforms compared to Hogwarts. And he would adapt to the new types of magic lessons. For example, if they focus more on group harmony in magic - making, Harry would need to learn to work in teams more effectively.
One possibility is that Harry would face different types of dark magic in Japan. Japanese dark wizards might have their own motives and methods. Harry, growing up in Japan, would have to adapt to the Japanese way of fighting dark magic. He could also be involved in cultural exchanges between the Japanese wizarding world and the British one. Maybe he'd introduce Quidditch to Japan but also learn about Japanese magical sports. His character would be shaped by the Japanese values of respect and perseverance, which would add new dimensions to his personality.
One plot idea could be that female Harry Potter, let's call her Hari, attends a Japanese wizarding school. There, she discovers unique Japanese magical creatures like the Kappa. She might struggle to adapt to the Japanese wizarding culture which is more honor - based compared to the British one. For example, she has to learn new spells with Japanese incantations and different wand - movements.
She would likely be more influenced by Japanese values such as respect for elders and harmony. So, instead of being as headstrong as the original Harry at times, she might be more diplomatic in her approach to problems. For instance, when facing a bully in the Japanese wizarding school, she might first try to resolve the issue through peaceful means rather than immediately retaliating.
Definitely Ginny. Since she's Harry's love interest in the original series, in the fanfiction about them growing up, she has a big role. She could be shown as a strong, independent witch who is equal to Harry in many ways. Draco Malfoy is also a character that features a lot. Sometimes, fanfiction explores his redemption arc further as he and Harry have to interact in the post - war wizarding world.
One difference could be his personality. Growing up in an orphanage might make him more independent and self - reliant from a young age. He would have to fend for himself more without the Dursleys' influence, which could also make him more distrustful of adults initially.
Well, for one thing, he might have a different accent. American wizards could have a more brash and outspoken style compared to the more reserved British ones in the original. Also, the school system might be more like American Muggle schools, with things like sports being more hyped up, perhaps a version of Quidditch that's more in line with American football in terms of fanfare.
Well, for one thing, he might speak French fluently. His magical education could be influenced by the French wizarding schools' curriculum. Maybe he'd have different friends, like French wizards and witches, and their culture would be a big part of his life.
In a 'Harry Potter grows up in space' fanfiction, the story could start with Harry being sent to space for some mysterious reason, perhaps to keep him safe from Voldemort. In space, he would grow up learning about both magic and the science of the cosmos. His wand might be modified to work in zero - gravity, and he could use magic to create artificial atmospheres on desolate planets. He might also form alliances with other space - faring magical beings, and together they would defend the universe from the forces of evil that are now spreading beyond Earth.
