I disagree. Take cover, wall of text incoming!

Bleach In Bleach it's all about Ichigo. He's the reason why Karagura has a higher than average number of Reishi sensitives (it's outright told at some point of the story), which in turn is the reason why it's this of all places that Aizen wants to sacrifice for making the key (he said he needed a place with high spiritual activity, which in turn means many Reishei sensitives).

The Fullbringers needed Ichigo, so it's natural that they'd congregate close to him.

The Vizards were also coming to Karakura in part for Ichigo and in part because Aizen was interested in the area.

And the rest of the story happens in Seireitei, so is not specific to Karakura or even Japan. But in the beginning of the story we hear there are many Shinigami watching over the world, each one with their own alloted area. We only see one of them in the district next to Karakura, commenting about how happy he was that Karakura wasn't his area of responsibility, but we know that there are others, most likely spread over the entire world.

So yes, whatever pieces of story are in the Human world, take place in this one town, but Kubo gave a good reason as to why that is so.

Naruto Naruto has conflicts and everything over the entire continent, including all the major factions present on it and several minor ones too, so at least the intra-continental part is fulfilled quite well.

In the manga itself we never even learn IF there are any other continents, much less whether they are inhabited or if those inhabitants can use chakra (considering how the Sage of Six Pathes gave chakra to the people, I doubt people on other continents would have gotten any).

LorR By the time of Frodo & Co, Valinor has been physically removed from the planet in a way of speaking, so of course it doesn't play any role. But every remaining part of the world is involved in the story. While the far east and the north are only mentioned, they were all tied into the last Ring war. In the north the Dwarfs, Wood Elves and good Humans were besieged by Orks and evil Humans from the east. And the entire east from north to south was in league with Sauron and sending their soldiers either to Mordor's armies or to the battle in the north.

While it's not told in the books themselves, the Silmarillion explains it. Originally the world was created flat with Valinor in the west and Middle Earth in the east. ...not quite, since Valinor was only created later, but that's a different matter. At some point the Valar decided to give Middle Earth to the mortal races and thus they "made all way curve" i.e. turned the world into a ball with the land of Valinor effectively "floating" in the heavens, though out of sight.

The book even desribes that for someone nearby, a ship going to Valinor would look like it's taking flight into the heavens (which can only be done with the active help of the Valar) and tells how after the Ring war ended, some Humans set out in ships and after going only west, they eventually arrived back at the east-end on Middle Earth. In other words Middle Earth is the only continent that remains on the planet.

Now in Fairy Tail, we know that other countries and inhabited continents exist and we know there are mages there, so here we have no plausible reason why everything would be concentrated in this country, except for the argument that maybe similarly important things happen outside of Fiore and we just havn't heard about. But while that excuse might work with events, it won't work with the Zodiacs, unless there's some good reason why they are all 'here' and we just havn't been told yet.
