How would you like to write your messages in a strictly-ordered way, knowing that one mistake could change the meaning of your sentence? It can happen in English, but it's easier to write Japanese wrong. David and Kaori visit a software researcher and test out software that is designed to read and identify handwritten Kanji characters. (David puts his skills to the test and fails.) David and Kaori also participate in a grueling judo workout, after which they learn about a computer that helps train judo students. Finally, Kaori shows David the next closest thing Japanese language has to the English alphabet.
