Narrative:

Flying the choshi 1 departure (runway 34). After takeoff, we initially flew the SID until about 10000 ft, then we were given a 130 degree heading to join the hme 096 degree radial to join the SID again. I could see the hme 096 degree radial on my navigation display so I pushed LNAV to capture it. But the FMC made a hard right turn after I pushed LNAV to join another radial on the SID. By then I got the aircraft going the right direction. I flew about 3 mi past the hme 096 degree radial. Departure control just said, 'you have flown through the radial.' I was unable to figure out how to join a radial on the CDU quickly enough.

Title: A B777 CREW, DEPARTING RJAA, FLEW THROUGH THEIR ASSIGNED INTERCEPT RADIAL.

Narrative: FLYING THE CHOSHI 1 DEP (RWY 34). AFTER TKOF, WE INITIALLY FLEW THE SID UNTIL ABOUT 10000 FT, THEN WE WERE GIVEN A 130 DEG HDG TO JOIN THE HME 096 DEG RADIAL TO JOIN THE SID AGAIN. I COULD SEE THE HME 096 DEG RADIAL ON MY NAV DISPLAY SO I PUSHED LNAV TO CAPTURE IT. BUT THE FMC MADE A HARD R TURN AFTER I PUSHED LNAV TO JOIN ANOTHER RADIAL ON THE SID. BY THEN I GOT THE ACFT GOING THE RIGHT DIRECTION. I FLEW ABOUT 3 MI PAST THE HME 096 DEG RADIAL. DEP CTL JUST SAID, 'YOU HAVE FLOWN THROUGH THE RADIAL.' I WAS UNABLE TO FIGURE OUT HOW TO JOIN A RADIAL ON THE CDU QUICKLY ENOUGH.
