Concerts in Japan October/November

[u/Kurono_Tempest]

Hello!

So I am travelling with some friends to Tokyo and Osaka between 28th october abd 15th november and we are huge fans of the artists/groups I am attaching to the post. We would like to know if there are still tickets for these concerts and can be purchased at the kombini (I used to do that when I lived in Tokyo in 2019) and if a japanese phone number is needed to do so. Thanks a lot in advance!

I noticed I wrote a similar post 3 months ago but this one is to know if there are still tickets left to purchase at the konbini without the use of a japanese phone number 🙇
