Dear G12 Parents,

I hope you have been good in the nice season after hot summer.
And in the next month, there will be held Sports Day.
I hope we can meet and talk at the event.

In September, there are the topics which students learned in this month below.
All students already know routines  and class rules in my class. So JNL class goes very well.
-What's Mass-media & Mass-communication
They discuss about mass communication and how we can define "mass communication". Also they search how languages are spreading and growing
-Language and Mass communication: Persuasive words
They learn what language effects mass media, and how words work for people on a poster.

In October, they will learn some a topic of Part2 below
- Language and Mass Communication: Persuasive words (CM, Speech, Song, Propaganda)

Many students are adjusting in a new G12 environment.
Sometimes they might be very busy or (and) confused because of it.
At the school, we all encourage them to adjust.
Also I really appreciate you for your everyday support.
If you have any questions, please don't hesitate to contact me.

Best regards,
Mr. Higa

Art Updates - September

Grade 12 artists have been learning about intellectual property rights and how appropriation and fair use applies to their work.  We hope to have art to share with you here soon.  In the meantime, this Tuesday, September 12 we will have a college presentation from the Savannah College of Art and Design.  It will take place from 3:15-4:15 in the grade 12 classroom, and is open to all high school students.  If you like art and think you might be interested in studying an art-related career path, this is a great opportunity to learn more.

Drawing Contest Announcement!  The Nakamura Keith Haring Collection is sponsoring their 9th annual International Children's Drawing Contest. It is open to students up to 17 years old, and submissions are due September 30th, so you'll need to get right to work.  The theme for this contest is "Harmony: a beautiful state of being when sounds, colors, people, or nature come together as one.  What is your version of harmony?"  Your work should be no bigger than A4, and may be any material as long as it's 2D.

Welcome to Chemistry Class

Dear parents and students.
I hope you had a great summer break.
This is Mr. Koc Secondary science (Chemistry) teacher. I will be teaching G9-12 IGCSE and IB Chemistry.

Starting from the beginning of this new academic year I will be teaching Redox processes  as the first unit of the year.

Students will start getting essential idea Redox (reduction–oxidation) reactions play a key role in many chemical and biochemical processes.
They will learn about;
·        Oxidation and reduction can be considered in terms of oxygen gain/hydrogen loss, electron transfer or change in oxidation number.
·        An oxidizing agent is reduced and a reducing agent is oxidized.
·        Variable oxidation numbers exist for transition metals and for most main-group non-metals.
·        The activity series ranks metals according to the ease with which they undergo oxidation.
·        Electrochemical cells
·        Voltaic cells convert energy from spontaneous, exothermic chemical processes to electrical energy.
·        Oxidation occurs at the anode (negative electrode) and reduction occurs at the cathode (positive electrode) in a voltaic cell.
·        Electrolytic cells convert electrical energy to chemical energy, by bringing about non-spontaneous processes.
·        Oxidation occurs at the anode (positive electrode) and reduction occurs at the cathode (negative electrode) in an electrolytic cell.

I wish you and our students to have a wonderful, fruitful and enjoyable new academic year with full of education.

Welcome back to English!

Dear Grade 12 parents and students,

Welcome back to English! I am very excited to continue teaching at HJIS and look forward to another great year with you all!

If you do not know me, this is my second year teaching at HJIS. I have previously taught in Kuwait and Spain before coming to Japan. I come from a large family of three brothers including a twin brother who is also an international teacher. In my teaching, I look towards developing a great sense of internationalism within my students, and I hope to continue to do this with your sons and daughters.

This year, we will continue the second half of the IB English Language and Literature course that we began last year. This semester, we will be focusing on Parts 2 (Language and Mass Communication) and 3 (Literature: Texts and Contexts) of the course.

We will begin with Part 2: Language and Mass Communication. The units we will be studying include:

Unit #1: Textual Bias
Unit #2: Advertising and Marketing
Unit #3:  Digital Media
Unit #4 (HL only): Language and the State

If you have any further questions about this course, please feel free to email me at

Thanks for your time and enjoy the last few days of summer!


Mr. Chris

Welcome to Japanese B class.

Hi,  I am happy with JapaneseB SL  teacher of G12 class this year, too.
First term, we forcus on global issues.
Our learning style like same as last year. But we need to more discuss to colleague  in this year.
So I want to students to think about a topic and develop their opions about it. By means of discussions. I:d like them to listen to different views and express their own openly and clearly.

Thank you

Now, I want to explain some important issues and procedures in my classroom.

1. IB Test:

IB is a-two-years-program. This year May, they will take the IB test. Since our students has covered most of the topics, they can have a good stating this year.We have a good atmosphere here and they like to help each other which is very good for IB. 

2. Jupiter:

Our school use the Jupiter grading system as you know. I will post my Homework, grading and behavior situation on Jupiter. I may write emails via Jupiter as well.

 3. Grading scale and Homework: 

In my Math class, my grading scale is given below:

Unit Test             :  35%
Term Test            :  30%
Homework           :  20%
Quiz-Project        :  15%

After I finish one of the major subject, I will give a unit test about the topic. It will not only measure them how much they could learn the topic but also it will be a good review about the topic.

After term, we have only one term test. It is gonna be taken in one of the last weeks of each term. In this test, I will ask questions about all subject that they cover within that term. Only the last term has a different situation. In that test, I will ask question from all over the year's topics. So they should remember all of the subjects.

Homework is one the most important issues that help student understand and solve questions easily. They have HW almost after every math class. In addition, I will give them some big projects that will be done with a group or individually .

4. Notebook: 

Notebook is very important for Secondary Math Classes. It is important that they keep the notes very neatly to have review later. To organize and write whole year's topics, they need a big A4 size square grid notebook. I definitely don't want them to use a small notebook and then they change their notebooks very frequently. 

They can buy a notebook themsleves from a stationary or internet. Otherwise our school buy ASKUL notebooks as you see in the picture. It is 400 yen and students can but it any time from me.

       5. Calculator:

       Graphic Design Calculator (GDC) is a compulsory item in IB math.It is strongly recommended that they should buy TI-84 Plus C model. There are many different prices on internet. I kindly advice you to use following web site to search and buy:

      5. Textbook:  In the classroom, we will follow Oxford Publishing Math IB HL Textbook and I will print out the pages and hand out the students. So they can study the topics at home in advance. But I think students may need another resource to make practice and study subjects.

For SL students, I can provide the materials and textbook for the Oxford book which is on the left. Then Students should buy the Cambridge one to study individually which is on the right.

For HL students, I will provide Oxford , I strongly recommend you buy The Cambridge one.

You can check and buy the books in the following links:



Important Note: 

You can find and download  the solutions of the Oxford books' exercises in the following web sites:

        I hope  we will have a satisfied and fulfilled year together with your kids. I know their passion on learning new areas. I am looking forward to teaching your children In IB curriculum.

     If you have any questions, please feel free to contact to me.

     Thank you very much.

  Have a nice day.
