This is another one of the questions that kishimoto sensei never actually addressed after the end of the series. It could be natural that they were left alone in forests , but is there any concrete evidence suggesting the same .
What happened to the bijuu's? Are they left alone in the forest or was there equal distribution amongst villages to leverage equal power? If yes , do we know about the existences of jinchuriki's post-naruto other than killer bee and naruto ?
"do we know about the existences of jinchuriki's post-naruto other than killer bee and naruto ?"
We know that jinchurikis are split from the ten tails (a manifestation of a chakra fruit tree) and we know there are other chakra fruits (Momoshiki had a bunch), so other jinchuriki could exist but no other jinchurikis have been confirmed - most tailed beasts are probably free in another unkown (unrevealed) dimension
