I agree, but signaling out JP games is pretty ridiculous, loads of western games do the same thing or are worse. Quest arrows, logs with step by step directions, crumb trails, tutorials out the ass, on the fly difficulty adjustment, etc. both do it but many times I have considered this one of the many reasons I like JP games better, they don't do this as much, almost every western game these days has loads of hand holding, compromises and "safe" design decisions to make games as accessible as possible. I think the better place to place blame is the big budget AAA games in general that are afraid to take risks or do anything that might put some people off.
There's a LOT more to the Japanese game industry than Nintendo. (I don't own any current Nintendo systems but have heard a lot of complaints about Skyward Sword, not sure if many others have been similar).
