I'm guessing you mean NRT
, not NTR...
You probably just got unlucky. Or it may depend on where you're coming from. Japan is a mountainous country so if you're coming in over the mountains there's very likely going to be mountain wave turbulence. But if you're coming into NRT
from the east, you're not going to experience that (you may still experience weather-related turbulence).
I feel mountain wave turbulence over Alaska every time I fly to Japan. I hate flying over Alaska; it can get really bad sometimes. I'm sure the same effect happens over the mountains in Japan.
I've flown into/out of NRT
ahead of or behind typhoons and the turbulence is pretty bad. But I've also flown in during sunny summer weather and it's been totally smooth.
also only has parallel runways so you might get some nasty crosswind landings sometimes that may not feel too smooth at touchdown. But every airplane has a crosswind limit so no matter what, you'd be below the operational crosswind limit. Airports are built taking the prevailing winds into account also so it's unlikely there are strong crosswinds all that often at NRT
. But I've experienced one pretty severe crosswind landing there and you may have also.
I'm tired of being a wanna-be league bowler. I wanna be a league bowler!
