Windshear is fairly common at most airports in Japan because of the mountainous nature around them - even the coastal airports such as Miyazaki, Oita and Sendai, and is esp. pronounced at the inland strips with the wind above 10 or 12 knots. The atis can be misleading because the wind given is a spot wind at the time, rather than the average over a certain period.
For your info, the following is the recommended engine failure procedure (to avoid obstacles) ]';l// used by a major operator in Japan, for 767/737/777 aircraft:
RWY 10
Follow extended rwy centreline (097) and commence RIGHT turn @ 1500' MSL then intercept 115 radial.
Fly HGE 115 radial to 25 dme then proceed to BINGO and hold at 4,000' MSL.
(737/767 acceleration alt. at or above 100' MSL. B777 accel alt at or above 2,600' MSL)
RWY 28
Follow extended rwy centreline (277) and commence LEFT turn @ 2,200' MSL or HGE 9 dme whicheber is sooner, direct KINOE, then proceed to BINGO and hold at 4,000' MSL.
(737/767 start accel at or above 2,200' MSL.
777 accel alt at or above 2,600' MSL)
Hope this helps.
