As others have noted, the Japanese have their fair share of criminality and violence against other groups of people on more recent times than slavery in the US.
About the damage to the environment, here the Japanese also have their own share.
If "feeling all one with the environment" includes fishing salmon in deep waters until they had been almost extincted, or whales or dolphins' slaughter on the beach, Japanese does not look special over any other groups in the world.
From my point of view, the difference in perception about robots is that they need them: they are getting old and someone or something must do the jobs.
In places like India there is so much people that robots become a real threat against people's jobs. In Japan if they do not use them, they will be dissapear as a nation.
