When the wind at Narita starts blowing out of the SW above 30kts and gusting often to 45+ kts, due to local topography the air feels like it is blowing through a cheese grater.
It is definitely not much fun having to approach in such conditions. Fortunately, Haneda is usually available and an approach to RWY22 is way more into wind and generally very smooth due to the airports Tokyo Bay location.
I agree with the comments of some in this thread. Too many crew in the past have shown too greater desire to push on to destination in adverse conditions, often resulting in bent and burnt a/c and pax.
