Out of interest how many hulls/lives have been lost in the last 50 yrs due to this rota in the lee of the buildings.
Having operated into Narita but not experienced this turbulence, how bad is it? and how does it compare to other airfields and in world that suffer with this? eg Funchal or even Gatwicks own 'Freddies Revenge'. At Heathrow unless the wind is straight down the strip you are likely to suffer rota, with severity dependant on wind speed.
Whilst a 3-4000m runway straight into wind always gets my vote, life is not like that. A cross wind with the associated considerations should maybe focus the mind, demand some handling skill and take ones attention away from the Su Doku it should not result in loss of hull or lives. The decision to avoid such a senario should have already been made e.g Go-Around, Hold off, divert or stay at home.
