1)A Trinity

[Learn More]

With a history of over 60 years, we provide community-based services.
We carefully understand each child’s characteristics and provide a career path that considers their needs.
We strive to provide an environment where all children can learn with peace of mind.
While complacency and dependence should be avoided during exam preparation, we firmly believe that a shared commitment to passing the target school’s entrance exam—a three-way partnership between the student, their family, and the Prep school teachers—will be a great source of strength for the student.
To ensure your child makes the best choice of school and proceeds with exam preparation with confidence, we at Hinoki Prep School have adopted “Trinity” as one of our guiding principles, clearly emphasizing the importance of this three-way partnership between the student, family, and prep school.

2)Elementary school students finish by 7 PM

[Learn More]

Do you eat dinner together as a family?
We don’t think it’s healthy for elementary school students to come home from prep school after 9 PM!
At Hinoki, regular classes for elementary school students end by 7 PM throughout the year. Exam preparation is tough, but we are working hard to find ways to provide the necessary instruction before families can have dinner together. We want to make the exam preparation as natural and stress-free as possible.

3)95%Retention Rate

[Learn More]

The reason for our 95%+ retention rate is that we “pay close attention to each and every student.” As a result, children grow and continue their studies.
What does a 95% retention rate mean? Every year, over 95% of students at Hinoki continue their studies. While many students switch between prep schools, very few students drop out at Hinoki. We are proud of this figure.

4)Passing the Entrance Exam for Your Desired School

[Learn More]

We will fully understand the wishes of your child and you, the parents, and produce the best possible result: passing the entrance exam for your desired school.
We take it very seriously that you, the parents, have chosen Hinoki from among the many prep schools available.
The clearest way we can respond to that feeling is by delivering the result of passing the entrance exam for your desired school.

5)Safety Measures

[Learn More]

At Hinoki, we take various measures to ensure the safety of our students.

Hinoki Official Smartphone App

We require parents to install the “Hinoki Official Smartphone App.”

The app offers numerous features that allow parents and the school to communicate closely and share information anytime, anywhere.

In case of emergency, we will contact parents via the “Hinoki Official Smartphone App” to inform them of the situation.
