The larger USDJPY trend is down so strength should be sold. It is unclear though whether or not the rally from 90.86 is complete.
As long as price remains below 99.52, bearish potential is significant. However, support from the 61.8% of 90.86-100.60 is a warning that 100.60 could be broken (since 61.8% is a level that tends to hold B waves of zigzags).
