This is 沢井正治 — someone who has never existed. 沢井正治 is 26 years old, lives in 宇都宮, Japan, at 小川町丸山3-2-3 (320-0001 宇都宮), and works at 土屋産業有限会社. The phone +817081091564 follows Japan's real numbering rules and the inbox behind the email actually opens, yet no detail here belongs to a real person — each one is assembled on the spot from real-world naming and address patterns. Any match with a real number or address is pure coincidence. Use 沢井正治 freely wherever you would rather not hand over your own details.
