Yes, if you want to talk to people in other parts of the world, you'll need a different app for that, because different parts of the world tend to use different apps (e.g., Chinese all use WeChat, Europeans seem to use WhatsApp, etc.). If you just want to talk to people in Japan, LINE is all you need. (Taiwan too, I think)
I talk to them on Facebook Messenger and Instagram personally. Which means "people in Japan" have them installed also. So you get my drift :)
One messenger is never "all you need" unless you pick your friends based on what app they use.
No, I don't.
Those people only have them to talk to you, because you're not in Japan and don't use LINE.
People in Japan who don't have foreign friends don't have this issue.
(Also, Instagram is not a messaging app. Messenger is.)
FTFY
> Those people only have them to talk to you
Nah, any single one of them has many more friends outside of Japan than I have friends in Japan. People living on an island with the most powerful passport in the world love to travel, breaking news.
> because you're not in Japan and don't use LINE.
It's true for all of the world except Japan :)
> (Also, Instagram is not a messaging app. Messenger is.)
That's just false. After it's stopped being about photos, it's just a messaging app for me and countless other people who don't care about its tiktok-mimicking reels and other drivel. It's actually very decent at being just a messenger.
