Asahi did a poll in mid July that asked for vote on the PR slate for the next Lower House election which in my view is a better view on relative party strength. They had (diff relative to their Jan 2020 poll)
LDP 35 (-2)
KP 6 (--)
HP 1 (+1) (surprised they are still being polled)
PNHK 2 (--)
JRP 10 (+4)
DPP 3
CDP 13 (-2)
RS 2 (-2)
SDP 2 (+1)
JCP 5 (-1)
Which party do you call JRP? I can't find it in the Wiki table.
