Posted by Romanization of Japanese names is easy, but translating a Japanese name back to its original form in Kanji with the correct probabilities is hard. There are many Kanji variants for a single Japanese name in its romanized form.
NamSor has made available a pre-trained PyTorch / OpenNMT model as an Open Source project on Github. NamSor also supports an a set of Open API services (most of them free up to 500 names per month) for Japanese names translation and classification.
This API can, for example, to recognize if a name is Japanese, Chinese or Korean. It can also determine the likely gender with the highest possible accuracy.
