If,it was hard on landing... we will have to wait and see how hard is hard! In any case looks like no fire O/B, prior to the landing? But, it does have the characteristics of the Narita accident. With or without A/T hard landings are generaly pilot induced and can be influenced by meteo conditions. But, as far as I can read it was a clear day, hot and a very long runway. Temp. inversion could also be a factor prior to touchdown.
