Primary School
Hazel Peralta
My name is Hazel Peralta, and I primarily teach English at WICS. I graduated from Oral Roberts University in Oklahoma, USA, with a bachelor’s in Writing. I later studied at Temple University, Tokyo, and received a master’s degree in Teaching English to Speakers of Other Languages (TESOL). I love languages, especially the English language, and I enjoy helping students on their individual journeys toward communication proficiency. As a teacher, I hope to show students that good communication skills not only allow them to share information effectively, but also let them use their God-given ability to create great works.
Erika Sataraka
Aloha! My name is Erika Sataraka, and I was born and raised in both Hawaii and Japan. I attended an international school in Japan and I graduated from New Hope Christian College in Oregon, USA, with a Bachelor of Science in Christian Counseling. I am excited to teach, learn, and grow with the students and see them grow into world changers for Jesus!
Hazel Joy Sablay-Aguinaldo
Mabuhay! My name is Hazel Joy Sablay-Aguinaldo, and I mainly teach Physical Education. I am a licensed Physical Therapist, registered in the Philippines with a Bachelor's Degree in Physical Therapy. I am also a licensed Autism Movement Therapy provider with training and certification in Program of Essential Competencies in Sensory Integration. I worked as a pediatric/school-based Physical Therapist in Malaysia for 12 years and dealt with children with special needs. Sensory and motor development plays a vital role in learning. We believe that our bodies are temples of the Holy Spirit. In WICS, we hope to develop physically literate students who have the knowledge, skills and confidence to enjoy a lifetime of healthful physical activity.
Isiah Large
Hello! My name is Isiah Large, and I am a teacher at WICS. I graduated from New Hope Christian College in Eugene, Oregon, USA. I love Jesus and basketball, and I want to relate to the children through what I love. I want to encourage, teach, and develop students in their academic abilities, passions, and faith, raising up the next generation. I hope that they have a bright future and shine for Jesus.
Izumi Nishiwaki
Hello! My name is Izumi Nishiwaki, and I am a receptionist at WICS Primary School. I also teach Japanese at WICS, having completed a Japanese teacher training course at Human Academy. In my free time, I enjoy singing and playing the guitar and piano. I hope to help my students know God's love and grow into strong young people who can love themselves and others.
Alecia Bonson
Hello! My name is Alecia Bonson. I am the fifth grade homeroom teacher at WICS. I graduated from Taylor University in Indiana, USA with a Bachelor of Science in Professional Writing. I also completed a Masters in Teaching English to Speakers of Other Languages (TESOL) through Biola University, which is located in California, USA. As a teacher, I want to encourage my students to hunger to learn more about God's world and to reflect Jesus' love to the people in it.
Miko Oyakawa
Hello! My name is Miko Oyakawa and I was born and raised in Ontario, Canada and have an Okinawan background. It's a blessing to be able to work in Japan and get reconnected to my cultural roots. My teaching degree is in the primary and junior divisions and I have 11 years of teaching experience. I'm privileged to be working in kindergarten, which I believe to be a very important stage in a child's development. I hope to help students develop a strong social, academic and spiritual foundation as they start their educational journey.
Secondary School
Chandler H. Im, Ph.D.
Secondary School Principal & Chaplain
Warm greetings, everyone! My family immigrated to the USA from South Korea when I was a teenager. After finishing high school in Northern Virginia, I earned a B.A. in Religious Studies (minor: Philosophy) from Boston University, an M.Div. from Westminster Seminary California, and a Ph.D. in Intercultural Studies from Fuller Theological Seminary. Before God sent me to Japan in 2016 to work at WICS, I had served at churches and mission agencies in the USA and Canada since 1995. An ordained Presbyterian pastor, I teach Bible, Christian Theology, Philosophy, and World Religions classes at WICS. As an assistant professor, I also teach doctoral students online for Faith Seminary in the USA. A few of my hobbies are reading, gardening, and traveling.

Debbie Im, M.Ed.
Vice Principal of Secondary School
My name is Debbie Im. I was born and raised in S. Korea, but lived and worked in the USA for 30 years. I earned these degrees from Western Washington University: a Master of Education, and a B.A. in East Asian Studies (minors: Japanese and TESOL). At WICS, I emphasize academic excellence based on Christian worldview and values. I pray that God would use me to instill in WICS students global perspectives, lifelong learning attitude, and caring for others. My husband and I have two adult children in America. I love reading, dancing, and singing.

Alletha Barnett
My name is Alletha Barnett. I head the science department at WICS Secondary School. I graduated from Evangel University in Missouri, USA, with a Bachelor of Science in Biology and Environmental Science (Mathematics minor) and have been working at WICS since 2016. Studying science in any language can be painful. I strive to use songs, raps, demonstrations, experiments, and videos to make science as engaging, accessible, and interesting as possible. By God’s grace, I hope to support and inspire the next generation of young people to use science expertly to glorify Him and help others.
Robert Edward Shiffer II
Hello! My name is Robert Edward Shiffer II. I grew up in Hawaii and later traveled to Japan where I have lived since 2016. While I have lived in Japan, I came to find my passion for education through my experiences volunteering, and I also came to realize Jesus’ guidance in my life. So that I could practice my hands and reflect God’s light as best I could, I studied to obtain my Master’s degree in TESOL (Teaching English to Speakers of Other Languages) from Temple University Japan. I eagerly look forward to doing my best to teach my future students.
Jonathan Tan
Hello! My name is Jonathan Tan, and I teach English, Mathematics and Physical Education at WICS. I graduated with a Bachelor of Science (Comp. Science with Mathematics) from the National University of Singapore and obtained a Postgraduate Diploma in Education (English, Physical Education) from the National Institute of Education. After teaching for over 15 years in Singapore, I came to Tokyo together with my wife and daughter in 2022 to begin serving God at WICS. As an educator, I believe in always giving off my best to my students and pointing them towards Christ.
Bill Komansilan
My name is Bill Komansilan and I came from Indonesia. I took my B.Ed. in Math Education minoring in Theology from Pelita Harapan University. I also graduated with an M.A. in learning, education, and technology from Oulu University in Finland. For five years, I taught at a Christian high school in Indonesia before I discovered God was calling me to share His good news particularly to places where most of the people barely hear of. I hope the math lessons I teach would help students see how orderly and unchanging our God is.
Christianna Traynor
My name is Christianna Traynor. I teach English and social studies at WICS. I grew up in Birmingham, Alabama, and moved to Tokyo in 2015. I received my Bachelor of Arts degree at the University of Alabama at Birmingham in Studio Art and Japanese Studies and later got my professional TESOL (Teaching English to Speakers of Other Languages) certificate from UC San Diego Extension. I enjoy baking, watching movies, and chatting about language and culture. Above all, I take great joy in following God’s call to teach in Tokyo and to share His love with each of my students.
