In line 4188 of data/ja.txt, the Japanese word for hello (konnichiwa) is spelled こんにちわ. However, it should be spelled こんにちは. This mistake may have occurred because the correct last character は is normally pronounced 'ha' but in this word is pronounced 'wa'. The incorrect last character わ is always pronounced 'wa', but is not the correct character for this word.
The same error occurs with a different word on the next line.
The IPA pronunciation notation for either line is not affected by this error as far as I can tell (I don't know how to read the IPA notation).
