Is Tona the same as TORF. This 10 am Tokyo and 8:00 pm EST rate is the first USD/JPY fix for every Japanese trading day. Rates trade from 8 pm est to 4 am est then the next set of interest rates are released.
To obtain Tona rates, must go through the BOJ or pay Quick Corp much money.
EURYO Yen Tibor appears to be on the discontinuation list for publication and use for markets.
The BOJ will never change headline interest rates because tiny movements in BOJ and Interest rate numbers massively changes the entire Japanese system and exchange rates. Also, the YCC bands maintain 0.5 to 1.5.
1m = 0.9466
3m = 0.94406
8 m = 0.9550
Total Interest rates
1.001
0.9550
0.9466
0.94406
0.939
0.913.
What we have is a break down to factor USD/JPY miles ahead and far better than normal 4 am rates.

Tianzuida ON TRADING 
So do you see a fall in USDJPY into tomorrow ?
I do see the USD/JPY drop as this pair is deeply overbought
