How much is a pip worth on AUD/JPY?
On AUD/JPY, one pip is a move of 0.01. For a standard lot (100,000 AUD), it is worth $6.76 on a dollar account, with an example USDJPY rate of 148.00.
Worked example
$10,000 account, 1% risk ($100). Long AUD/JPY at 97.000 with a stop at 96.750, that is 25.0 pips. Each lot would lose $168.92 at the stop: 100 ÷ 168.92 = 0.59 lots, rounded down so you never exceed your risk.

FAQ

How much should I risk per trade? 0.25% to 1% of the account is the norm at prop firms: enough for wins to matter, little enough to absorb a losing streak. Read our guide on how to pass a prop firm challenge.
