Learn programming through Minecraft,
a school for the AI era.
From 1st grade. No PC experience needed.
PCs and materials all provided. Start with a free trial.
Why 8x9?
Beyond "technology" lies "purpose."
Our school is not just a place to teach the skill of writing code.
Programming is only a tool. What matters is "who you build for" and "what you build" with that tool.
Our founder is an active engineer with over 20 years in the software industry.
Minecraft Day, held every single month for 10 years, and two in-house learning tools (hackCraft2 / WorldCraft AI)——
children start because it's "fun," and before they know it, they "can do it." We keep building that kind of environment.
Taught directly by the founder.
8x9 Tokyo is a classroom where Masafumi Terazono, who founded 8x9 in Kobe and Osaka, came to Tokyo to teach the lessons in person.
Because our classes are small, each child can take on ambitious curricula that set us apart from our Kansai classrooms, at their own pace.
Building everything from how semiconductors work up to a CPU in Minecraft, analyzing the Minecraft world with data, taking on competitive programming and real mod development——
the person who created the materials works with the children face to face.
Curriculum Supervision & Adoption
8x9's materials and curriculum are also adopted by educational institutions and services for children.

Minecraft AI Course
¥13,200/month (incl. tax)
"Raising children who learn AI and can put AI to use."
Starting from the Minecraft kids love, children naturally engage with both AI and programming.
No PC experience needed. The school provides all PCs and materials, so there is zero extra cost for parents.

See what each chapter covers (5 chapters)
- Chapter 1: Get comfortable with the PC via Minecraft (Months 1–4)
- Through the world of Minecraft, children get used to mouse control, keyboard input, and typing. AI is not used yet—first they experience "PCs are fun!"
- Chapter 2: Learn in Minecraft's AI World (Months 5–8)
- With AI materials built into the Minecraft world, children learn experientially while playing—what AI is, and where AI exists around us.
- Chapter 3: Use AI as a tool (Months 9–12)
- Practice using AI as your own tool. Give AI a role and converse with it, create stories together, and build the ability to verify for yourself whether AI's output is correct.
- Chapter 4: AI × coding (Months 13–18)
- Take on block coding in the Minecraft world. While asking AI for hints, learn sequencing, loops, and conditionals.
- Chapter 5: Deepening AI × coding (Months 19–24)
- Try programming with functions and variables, game creation, and automation. As a graduation project, children finish "their very own adventure story" into a PDF together with AI.
Goals over 2 years
- Type proficiently
- Use AI as a tool (instruct, evaluate, improve)
- Grasp the basics of programming (loops, conditionals, organizing commands)
Programming Course
¥13,200/month (incl. tax)
Build the power to bring "what you want to make" to life, within the world of Minecraft.
A programming language is just a tool. What matters is "what you make" with it.
Using our in-house tools hackCraft2 and WorldCraft AI, children give shape to what they themselves want to do.
Four tracks to match each child's interests
Detail pages are in Japanese.
More things children can build
hackCraft2 — for beginners and intermediates
WorldCraft AI — for intermediates and advanced learners
Goals
- Turn what they want to make into code, in a language that fits their interests
- Break a problem down and think it through step by step (computer science thinking)
- Push through errors, investigating and fixing them on their own—with AI's help, too
One-on-One Course
¥13,200/month (incl. tax)
An active-engineer mentor provides individual support online.
Prioritizing "what the child wants to do," learners gain advanced IT skills hands-on through building real projects.
An original system that makes growth "visible"
Our original curriculum system records each lesson report and your child's growth.
Check anytime from the LINE app, so you can watch their progress even when you're not at the classroom.

Frequently Asked Questions (Q&A)
From what age can my child enroll?
Children can enroll from the 1st grade of elementary school.
At first, we carefully start with typing, basic PC operation, and internet literacy. We naturally draw out an interest in "programming" and "making things," building the basics while having fun.
What does the curriculum look like after mastering the basics?
After building the basics in the Minecraft AI Course, children take on serious coding in the Programming Course. Beyond that, we also offer the One-on-One Course with an active-engineer mentor.
It's a three-stage structure that lets children step up comfortably, matched to their growth and what they want to do.
Is it okay if my child is a complete PC beginner?
Yes, absolutely no problem.
We teach from how to hold the mouse and keyboard input, so even children who have never touched a PC can start with peace of mind.
Do we need to bring our own PC?
For the Minecraft AI Course, the school provides all PCs and materials, so there's no need to bring anything.
For the Programming Course, we generally ask that students bring their own laptop.
A high-spec PC is not required (our materials work fine even on a used PC in the ¥20,000 range). We also help with purchasing an affordable PC, so please feel free to ask.
Are make-up lessons available if my child is absent?
If you contact us by 23:59 the day before the reserved lesson, you can carry a missed lesson over to the following month. (Lessons cannot be carried over for two months or more.)
Do parents need PC knowledge?
It helps your child's learning if the family gains knowledge together, giving you a deeper understanding—but there's no need to force yourself to learn it.
Our instructors explain in the clearest possible terms and provide support.
