oh- and its customary on flights to/from japan in F (at least on JL, UA, AA, NH) to prebook the Japanese bento meal- even at time of making the reservation-to ensure that you do get it- so they do not overcater this item
there may be a few loaded anyway but its often not available if you haven't preordered
we've had this six times so far this year- and maybe its "truly japanese" but neither me, my wife or son really enjoyed the flavors and textures
i am sure the native japanese people were oohing and aaahing over the broad range of bites, but for us, a lot of it was "icky"
sorry, sea urchin guts are not my favorite...
