One thing you have to take into account is that mangas are published in different magazines that have different schedules for releases. For example, shounen jump is a weekly magazine, while a lot of shoujo magazines are monthly magazines. So, skip beat literally gets one chapter out per month. That’s just how magazines work.
Also, there’s large studios involved in the webcomic industry, as well as unhealthy work conditions.(remember the one artist that had a miscarriage because of the work, and she was still expected to work?). Most mangakas have a few assistants to help them of course, but it’s nothing compared to the whole studios that produce some of our beloved manhwas.
I love manhwas a lot, probably more than manga, but I just wanted to inform about some stuff. The frequency of releases for manhwas should honestly not be a “standard” to judge by, as it’s a result of the unhealthy work environment in that industry.

“… But it can’t compete with Korea.”
My point still stands. You compared traditional manga with a country… What you should've said was Korean webtoons. However, it still makes zero sense to compare the two. Now, what would make sense is if you were to compare traditional manga with traditional manhwa. Not all manhwas are webtoons.
Honestly, outside of popular shounen mangas like Naruto, hunter x Hunter, AOT, the Japanese mangas are just not the thing anymore.
I understand how long it takes to create mangas, store boarding, drawing by hand, etc. But it can't compete with Korea.
Manhwas have faster uploads, are colourful, and are more widely available since they are digital.
This manga, for example, was first published in 2002... and is only at 333 chapters
Lookism came out in 2015 and it at over 550 chapters at this point with a much large character base, a longer timeline and more character background and progress than in the little pinky of skip beat.
This is honestly just my opinion. I could be 100% wrong, and I admit that. I also haven't really found a shoujo manga i loved in year because of pauses, delays and cancellations but i've found so many romance manhwas that I love.
