Trip to South Korea from Japan daily

Hi, Is it possible to take a daily trip to South Korea from Japan? Do people take daily trips? I heard it's an hour flight. Would it be too exhausting to go in the morning and go back to Japan at night time?

It's entirely possible but doesn't make sense to me.
1 hour flight time + time to get to airport + 1 hour before flight + immigration + travel to centre at the other end means you have little time actually seeing the place.
Go for at least a night, 2 preferrably.

I guess you mean a daytrip. Instead of going there every day like a commute.
Yes, as PP was saying a daytrip is theoretically possible but that�fs probably normally only done by very busy businesses travelers.

One day trip is done by business travelers, mostly between Haneda and Gimpo. Normal tourists wouldn't do so.
On the contrary, tourists stay 3 - 5 days range in each country between Japan and South Korea. Instead, there're more frequent tourists, visiting 5 - 10 times, than other destinations.
