USD/JPY is steadying after the earlier sell-off, presently at 87.80 from sesson low 87.57.

Earlier 88.00 barrier option interest was blown up when Kampo failed to turn up around said level as expected (well we heard no reports of them being active) and stops just below 88.00 were tripped accelerating the downside move.

Sources now report that Kampo was eventually cited down around 87.60 lending much-needed support.
