According to their chief currency strategist, Daisaku Ueno

Says that BOJ governor's earlier comments here is to add further downward pressure on USD/JPY which could push it towards 105 in the near term.

Ueno adds that it will initially test the 16 February low of 105.55, while saying that sentiment towards USD/JPY has already been weighed by concerns over US protectionism and that yen-buying needs also tend to be strong around this time of the year (likely referencing to the Japanese fiscal year ending in March, hence repatriation of funds).

He also adds that it is "unclear why Kuroda made specific comments about monetary exit when downward pressure on USD/JPY was already in place". He adds that the market may need to watch closely for what Kuroda has to say after the BOJ policy meeting next week.

I do second his final comments there. Kuroda has been known to overstep a little and then backtrack on his comments, but there's no denying that the downtrend for USD/JPY looks towards testing the lows of this year again.
