Japan is a reclusive, painfully polite, and hard-working character. He has a habit of answering difficult demands with vague replies, such as "Perhaps next time", "I'll think about it", and "I will try my best". The answer for all of these means "No". He seems to have a problem with others being in his personal space, for he gets uncomfortable if anyone touches him or gets too close. Although Japan has trouble understanding "western culture", and the things he believe is "normal" generally isn't, he is very good with technology, and is especially proficient in making things smaller and compact. He enjoys watching the seasons change and has many occasions for almost every month, which keeps him busy the whole year. Generally quiet, he is often depicted with the attitude of a businesslike old man. Japan also has an Otaku side to his usually quiet character. He loves cute things, and is shown to have had a guinea pig and a dog at one point (when he came out of isolation/hikikimori), and is the owner of Japancat, which he calls Tama.
