Japan has 14 JGP spots, four of which will go to Rena and Mao (2 each), leaving 10 to be distributed among all other skaters.
Sae is likely to focus on Pairs (possible GP assignment) and Sumire on Ice Dance (likely to receive JGP assignments), and Hana will be doing the Sr Grand Prix circuit, but that still leaves 14 skaters who might try for a JGP spot.
The most likely candidates to get JGP assignments currently seem to be Ikura, Yo, Ayumi, Ami and Riria, but especially with the younger girls, the development over one off-season can be quite substantial. The solo jump for next season is also the Flip, which offers new opportunities and new challenges. (For example, Yo can now do a 3Lz+3T in the SP again, but also has to do a 3F if she wants to stay in contention.)
