Computer science has a long tradition of not or misattributing inventions. Unsurprisingly, the early contributions from Japan can be found in the historical summaries by Schmidhuber (see e.g. https://people.idsia.ch/~juergen/deep-learning-history.html https://people.idsia.ch/~juergen/deep-learning-history.html), who seems to be one of the few who cares about mentioning the correct authors.
