The Wikipedia has the following information about this codepoint:

〒 (郵便記号, yūbin kigō) is the service mark of Japan Post and its successor, Japan Post Holdings, the postal operator in Japan. It is also used as a Japanese postal code mark since the introduction of the latter in 1968. Historically, it was used by the Ministry of Communications (逓信省, Teishin-shō), which operated the postal service. The mark is a stylized katakana syllable te (テ), from the word teishin (逓信（テイシン）, communications). The mark was introduced on February 8, 1887 (Meiji 20.2.8).
