His friends like Sasuke, Sakura, and Kakashi might visit. They could come to relax and catch up with Naruto.
Other ninjas from different villages could visit. Since Naruto is well - known, they would be curious to see his inn. Also, travelers passing through the village might stop by for a stay. And maybe some of the older ninjas who used to know Naruto when he was young would come to see how he's doing with his new business.
I think all kinds of people would visit Naruto's inn. The local villagers would surely drop in for a meal or a drink. Then there are the young ninjas who look up to Naruto as a hero. They would be eager to visit the inn and maybe get some advice from him. Foreign diplomats or envoys might also stay at the inn when they come to the village for important meetings. And let's not forget the wandering samurai or ronin who are just passing through the area. They would be attracted to the inn because of Naruto's reputation.
Maybe Naruto turns the inn into a place where ninjas from all over can rest and share their stories. It could be a hub for information exchange.
The old ninja masters could visit Naruto's shop too. They might be interested in seeing what new and innovative things Naruto is doing with his shop. Some of Naruto's former teachers like Kakashi could also drop by regularly. He might give Naruto some advice on running the business or just come to have a friendly chat while browsing the items in the shop.
In a fanfiction set in an inn, Itachi might be there to pass on some crucial information to Sasuke and Naruto. He could choose the inn as a neutral and unexpected place. Sasuke would be hesitant to trust Itachi, but Naruto's presence might make him more receptive. They could engage in a battle of ideologies, with Naruto representing hope and friendship, Sasuke representing vengeance and Itachi representing sacrifice. The inn becomes the backdrop for this intense encounter.
Sasuke might be one of the main visitors. Their relationship has always been complex, and perhaps Sasuke is curious about Naruto's new venture. Shikamaru could also be a regular. He's smart and might be interested in the strategy involved in casino games. And then there's Kakashi. He seems like the type who would drop by now and then, just to keep an eye on Naruto and see how he's running things.
I think Hinata would definitely visit Naruto's garden. She has always been interested in Naruto, and his garden would be a wonderful place for them to spend time together. Also, the senseis like Kakashi might drop by. He could give Naruto some advice on how to manage the garden in a more efficient and unique way, maybe even sharing some knowledge about plants that could be useful in ninja training.
Sasuke could visit him. Despite their differences in the past, they have a deep bond. Sasuke might come to check on Naruto, or maybe he also wants some time away from the world and thinks Naruto's seclusion place is a good spot.
His teammates, Sasuke and Sakura, would surely visit him. They are his closest comrades, and they would be worried about his condition.
His old ninja friends like Sasuke, Sakura could be regulars.
There could be a situation where the inn is under attack by a common enemy. Itachi, Sasuke and Naruto have to put aside their differences and work together to defend it. They use their unique skills - Itachi's genjutsu, Sasuke's fire - based jutsu and Naruto's shadow clones - to fend off the attackers. This experience bonds them in a new way and they leave the inn with a newfound respect for each other.
One challenge could be dealing with competitors. If his company is in a competitive field like ninja training, there might be other established companies or individuals who see him as a threat and try to undermine his business.
