Greetings from the PTF

PTF Connections:

This month has been an amazing month for our students. Despite the many typhoon interruptions, the PTF held its first coin war, raising over ¥170,000. We would like to thank our students, parents, and teachers for their cooperation in making it such a successful fundraiser, exceeding our expectations. As a result, the ice cream party will be for all students! The winners will receive select prizes from their classroom wish list. For example, the elementary winner, Mr. Logan’s 3.2 Class, has requested beanbag chairs and lamps for the reading corner.

In addition, we will be using these funds to purchase…

  • Science goggles and a variety of indoor board games for the elementary students.
  • For secondary, funds will be given to the mission team to assist in their trip to the Philippines. The secondary winners will also receive fun prizes like homework passes and other prizes, dependent on their teachers.

We would also like to thank our parents for attending the Japanese college guidance session.  There were more than 30 parents at this event, allowing Mr. Suzuki to explain the updated college information in Japan. This will help secondary students and parents in making informed decisions about their future college plans. We are hoping to plan another college guidance session again to promote awareness of colleges in Japan and around the world.


On November 2nd during parent teacher conferences, the PTF will be hosting a flea market.  This is a great opportunity for parents and students to earn money selling used items. And possibly a chance to get a good bargain! Participation is straightforward and easy—no booth fee or application, instead, simply bring whatever goods you want to sell and do so from 9AM to 12PM. Also, if you do not have a table and would rather not be on the ground, simply rent one from us for $5.00 or ¥500. Many groups will be fundraising for class trips, sports trips, and mission trips. There will also be snacks and drinks for purchase or donation.

Holiday Market

On November 17th, the PTF will host our annual Holiday Market. This will include a selection of local craft artists, international foods, and an outdoor festival for the kids. Details for the outside festival are still in progress; however, we will definitely have a selection of carnival-style games. Therefore, please continue to check our Facebook, LINE, or the OCSI website for updates. And join us for this fun family event. We look forward to seeing you there!

In addition, we just ordered new OCSI sweatshirts, and they are available for purchase! So, please check them out in our PTF “mini store” in the corner of the front office. We are also selling PTF t-shirts and OCSI towels there.

If you have any questions, suggestions, comments, or concerns, please feel free to email us at ptf@ocsi.org.

Our students are involved in science

Elementary Connections:

This school year OCSI elementary is implementing the Next Generation Science Standards from kindergarten through 5th grade. Our new curriculum includes both hands-on experiences and literacy connections. Science and engineering education includes investigations into the natural world as well as how engineers design and build systems. We hope to encourage all students to build, deepen, and apply their knowledge of core ideas in the following domains: physical science, life science, earth and space science, and engineering.

What does this look like in your child’s classroom?

  • Pre-K: Students have the opportunity to take care of stuffed animals in the dramatic play center which is set up like a pet store, and they are learning how to care for animals.
  • 1st grade: Students investigated how an apple tree grows and changes. They made predictions and then looked at the inside of an apple and counted the seeds and made homemade applesauce. Next, they’ll be exploring how an animal’s body parts help it live, grow, and find and catch food.

  • 2nd grade: Students learned about habitats and biomes and created a classroom pond habitat they could develop and add their own animals to.
  • 4th grade: Students began an investigation with magnets and explored the question, “What sticks to magnets?” Students made predictions about what materials would stick to the magnets, as well as discovered the two sides of a magnet and the invisible magnetic field.

Students are our future


OCSI Connections:

At OCSI, we believe that students are our future. We believe that students are full of potential, and that they are responsible for their learning and responsible for using it to serve God and others. Consequently, we are excited that…

  • Kindergarteners have increased their reading skills.
  • Second graders have increased their understanding of map, globes, and how to give directions using north, south, east, and west.
  • Fifth grade mathematicians focused on factorization and exponents.
  • Seventh grade scientists learned how food molecules travel through the body.
  • Ninth grade historians deepened their understanding of the role of law in society.
  • Eleventh grade writers demonstrated their understanding of The Screwtape Letters, satire, human nature, and letter organization by writing a new Screwtape letter satirizing a flaw in human nature that they see at school.
  • Twelfth graders studied how calorie intake affects body composition.

To learn more about what’s happening at OCSI, check us out on social media (Facebook, Instagram, Twitter) and check out PTF on Facebook.

On October 8, OCSI hosted an open house for parents interested in enrolling their children. The open house included an opening presentation and campus tour. Thanks for continuing to recommend OCSI!

Secondary Connections:

We’re off to a great start! Thank you for allowing OCSI to partner with you in your child’s education! If you know others that might be interested in joining the OCSI family, please use the Referral Coupon for a possible tuition discount.

Today is progress report day. Please check your student’s grades online through Jupiter, as paper report cards will no longer be sent home. If you have any issues with your Jupiter login, please let me know.

Our College and Career Counselors, Mr. Suzuki and Mrs. Lopez, have been meeting with student to help them in meeting their post-high school goals. We have already had several universities visit and share with our students. If you are interested in attended college information sessions, please refer to the OCSI calendar for dates.

Dress code is always an issue for students, and I want clarify a couple of things:

  • Skirts/shorts should reach mid-thigh in front and back.
  • Ripped jeans are acceptable as long as no skin is showing. For example: there are tights under them or a patch has been sewn to cover the hole. 3) Skinny jeans, for both boys and girls, must fit in a modest manner. Administration reserves the right to determine if pants are too tight and need to be changed.

There have been a few questions about attendance:

  • If your child needs to leave campus early for any reason, please come to the office and let them know you will be taking your child. The office staff will contact your child’s class and have them sent to the office. Please allow at least 10 minutes for your child to make it to the office after your arrival. Students must check-out in the office, with a parent, before leaving campus. Please keep your student informed, as much as possible, so they can communicate with their teachers about missing class.
  • Students may only miss 7 periods of any class, each quarter, to receive credit. These are any absences that are not school related (excused/unexcused). If your child will be absent for an extended period, please notify the office ahead of time so we are aware and teachers can prepare classwork for you child before leaving. In cases of 8 or more absences, extenuating circumstances will be considered.
  • Please remember that morning supervision does not begin until 8:00 am. In addition, students should be off campus by 3:30 pm.

As always, if you have any questions or concerns please don’t hesitate to contact me. Have a fantastic weekend!

We want our students to learn about Jesus

We want our students to learn about Jesus! So, we provide Christian teachers, teach the Bible, and go to camp—check out the video! One elementary teacher shared, “Four of the students in my cabin said they had not ever made decisions for Christ yet and weren’t ready to pray with me at the time, but were doing much reflection as our speaker shared about the different soils.”


  • Pray that these 4 students would follow Jesus.
  • Pray that God will use high school camp (September 24-26) to work in students’ hearts.
  • Praise God that 9 elementary students are attending a lunchtime Bible study.

Thanks for being involved in God’s work in Japan!
