The USDJPY recently put in a beautiful rising channel right into a previous level of structure resistance...and it failed. Now that we've broken the simple pattern 7 the previous level of structure, there's a chance that we can continue going higher & a pullback trade would be an excellent place to get involved prior to the move.
Something to keep in the back of your mind however is that although there is a smaller structure zone above that would make a good place for target, we are technically trading within the higher timeframe structure zone.
