  • My name is Esther Byeongmi Lee, and I have the great privilege of serving as the first staff member of WICS. Before joining the school’s founding committee, I received a clear and heartfelt calling from God—to nurture students as Christ-centered leaders who will serve His Kingdom and impact the nations.

    With a major in Education and a minor in English Education, I am passionate about teaching and wholeheartedly committed to the growth of our students. It is my joy and honor to walk alongside them as they develop through the education offered at WICS.

  • Hello! My name is Miko Oyakawa and I was born and raised in Northern Ontario, Canada. As you may be able to tell from my name, I am of Okinawan descent, however, it wasn’t until 2015 that I moved to Japan for the first time. Since then, I believe God has planted in me a heart for the country of my roots. Serving in the WICS community, truly a tight-knit family, has been a great privilege and blessing. By His grace, I look forward to growing alongside the students, staff and families for many years to come.

An ordained Presbyterian pastor, I teach Bible, Christian Theology, Philosophy, and World Religions classes at WICS. As an adjunct professor in the USA, I also teach online doctoral seminary students. A few of my hobbies are reading, gardening, and traveling.
