Narrative:

On final approach, tower reported severe turbulence between 300-1500 ft AGL reported by other aircraft. Winds at altitude for runway 16R were 275 degrees, 75 KTS at 2500 ft AGL. Runway winds 200 degrees at 12-15 KTS. We elected to go around with 38000 pounds fuel on board. 1 DC10 and 1 B747-400 landed with same precaution warning. On return to airport, we requested landing information. Aircraft reported 12-15 KTS windshear. We asked for turbulence report from airport on landing rollout and got moderate. We landed fast with moderate turbulence. Normal. How could other aircraft land with severe turbulence reported? Why wasn't airport closed for severe turbulence? Severe turbulence equals uncontrollable flight. Controllers need training to define conditions.

Title: B747-200 GOES AROUND AFTER RECEIVING RPTS OF SEVERE TURB AT RJAA.

Narrative: ON FINAL APCH, TWR RPTED SEVERE TURB BTWN 300-1500 FT AGL RPTED BY OTHER ACFT. WINDS AT ALT FOR RWY 16R WERE 275 DEGS, 75 KTS AT 2500 FT AGL. RWY WINDS 200 DEGS AT 12-15 KTS. WE ELECTED TO GO AROUND WITH 38000 LBS FUEL ON BOARD. 1 DC10 AND 1 B747-400 LANDED WITH SAME PRECAUTION WARNING. ON RETURN TO ARPT, WE REQUESTED LNDG INFO. ACFT RPTED 12-15 KTS WINDSHEAR. WE ASKED FOR TURB RPT FROM ARPT ON LNDG ROLLOUT AND GOT MODERATE. WE LANDED FAST WITH MODERATE TURB. NORMAL. HOW COULD OTHER ACFT LAND WITH SEVERE TURB RPTED? WHY WASN'T ARPT CLOSED FOR SEVERE TURB? SEVERE TURB EQUALS UNCTLABLE FLT. CTLRS NEED TRAINING TO DEFINE CONDITIONS.
