Meet the Kettemans, IM Missionaries to Japan

Jack and Ashley recently completed a 2.5 year internship and have been appointed to return to Japan as career missionaries. After 14 years of youth/family ministry in the States, they moved to Tokyo near the end of 2018 to join the Hope Alive church-planting team, helping establish a bilingual church in Tokorozawa.

The Kettemans hope to return to Japan in the Summer of 2022. As new career missionaries, they will begin the next term in a full-time language school for 2 years, still participating at Hope Alive on a smaller scale, then re-entering full-time ministry better equipped to share the Gospel in the Japanese language.

The Kettemans have three kids: Jane, Callie, and Carter.

– Jane loves reading and playing percussion, piano, and basketball. Her favorite Japanese snack is ume boshi (pickled plum).

– Callie also loves reading, playing flute, singing harmony, and running. Her favorite Japanese snack is onigiri (seaweed-wrapped rice balls).

– Carter is learning to read, loves Legos ®, dinosaurs, and vehicles of all kinds. His favorite Japanese snack is Hi-Chew ® candy.

Why Japan?

We’re serving in Japan for two reasons: God’s call and the immense need. The Japanese people are considered the 2nd largest Unreached People Group (UPG) on the planet. Less than 1% of Japan’s population of about 126,000,000 is made up of Evangelical Christians. There is only 1 church for every 16,000 people, and many Japanese people have never even met a Christian.

Depression, stress, social disorders, and other mental health struggles are widespread, and suicide is the leading cause of death for those from age 44 down to 10 year-olds. Since the start of the COVID-19 pandemic, there has been an increase in suicides among mothers. Japan needs the Good News of Jesus and the Living Hope that only He provides

A few years ago (thanks to IM Missionaries to Japan), God used this powerful video to help spur us toward serving in Japan.

God also called us to this ministry through a variety of experiences and interactions, as well as prayer and Bible study. The Lord brought Japan into our lives in a number of ways:

  • Through longtime family friendship with IM Missionaries to Japan.
  • Through short-term trips that allowed us to explore the culture, participate in ministry, and have our eyes opened to see how many are walking in darkness without Christ.
  • Through God’s weaving of Japan into our daughter Jane’s life from a young age.
  • Through the Lord directly impressing obedience to His call on Callie’s heart.
  • and through an immediate open door to be part of a new church-planting team, just at the time we said “yes” to serving overseas.
