USD/JPY technical indicators

as many of you know, the USD/JPY is the prefered pair for those who like trading with trend lines (support/resistance/pivot levels) because of the “herd mentality” of Japanese traders the strong support/resistance levels that result.

If you know what I am talking about, is it recommended to trade during the hours of the Japanese market (7 p.m.-4 a.m. EST) in order to maximize this effect.

In other words, is there evidence to suggest that the stronger resistance/support levels resulting from the japanese herd mentality are even stronger during the Japanese market hours as opposed to off hours? thanks for your help
