Pretty much not all of Niji foreign element are able to go due to various circumstances, with Pomu and Finana's that are more damning because it came up pretty late (aka one-two days before the event) and Pomu is saddened about it. Also ended up making things getting restructured like how one section on Nijifes that supposed to have Ethyria innit ended up becoming pre-recorded affair and how due to the fact that only half of the ex-KR that was able to go to Japan, their section is turned into a bog-standard podcast stuff.I've seen a tweet about not all niji EN being able to go to Japan for 3d, that's sad
Still, not all is lost. The 3D is still happening, and with Selen being able to go to Japan then what she and Nagao promised back in the day (being able to meet up and play soccer together) would be happening as well.
