Actually, just Mahito Yokota and Takeshi Hama credited for Super Mario 3D Land
here. But I'm not sure where those credits come from, as the game credits were a list of all staff. It'd make sense if Yuya Takezawa and Shigetoshi Gohara once again had an implementation role. But maybe Asuka Hayazaki was involved too.
It seems that, contrary to the Kyoto branch, the Nintendo EAD Tokyo branch likes to hire more experienced musicians. Mahito Yokota worked on several scores at KOEI first. Takeshi Hama did some nice work on Devil May Cry's anime and later worked for noisycroak.
