I have been building a small Japanese learning system together with one of my regular viewers, Twin-san.
At first, this began in a simple way.
He started writing short Japanese sentences every day as practice.
I checked them, scored them, and we began to see something interesting:
even very small sentences could become part of a larger game.
A sentence was no longer just a sentence.
It could become progress.
It could become growth.
It could become part of a story.
That idea gradually led to what I now call the Japanese Challenge system.
What is Japanese Challenge?
Japanese Challenge is a simple way to earn points by using Japanese during live streams.
The basic idea is this:
- use Japanese in a way that fits the current situation
- receive a score
- record that score
- use the accumulated points later for character growth in the TRPG story
This means Japanese practice is no longer separated from play.
Instead, Japanese becomes part of how the game world moves forward.
A sentence can be short.
It does not need to be perfect.
What matters is that it is used meaningfully.
This is currently a Twitch-based system
At the moment, this system is designed only for my Twitch channel.
That is important to say clearly.
For now, Japanese Challenge is not a general public system that works everywhere.
It is something being developed inside the live environment of Twitch, where I can directly see the flow of the game, the context of the moment, and the Japanese being used.
You can find the channel here:
Because the challenge depends on live context, stream atmosphere, and direct scoring, Twitch is currently the natural home for it.
Later, I may expand or adapt the idea elsewhere.
But for now, Twitch is where it lives.
How the challenge works
During a stream, a participant may freely say or type a Japanese sentence that matches the current scene.
This is important:
the goal is not to answer a fixed quiz question.
Instead, the idea is to express something naturally within the situation.
For example, a person might say:
- what they see
- what they want to do
- what feels dangerous
- what looks interesting
- what they want to ask
That freedom matters, because language becomes much more alive when it is used as self-expression rather than only as a test answer.
After using Japanese, the participant may use the Twitch Channel Point reward Japanese Challenge to mark it as an official scored attempt.
Then I judge it and give a score.
The participant keeps their own record.
How the scoring works
Each sentence is judged in three parts:
1. Does it fit the scene?
Does the sentence match the current situation?
2. Does it make sense as a sentence?
Even if it is simple, does it work as Japanese?
3. Is it interesting, vivid, or fun?
Does it feel memorable, expressive, or lively?
Each category is scored from 0 to 5, for a total of up to 15 points.
This means even simple Japanese can still score well.
A very short sentence can still matter.
In fact, I want this system to reward not only technical accuracy, but also the courage to express something and the ability to bring a scene to life.
Sometimes the scoring will also include a little bit of personality.
If a sentence is charming, funny, or unexpectedly perfect for the moment, that may matter too.
Yes, this means a sentence about a cat may sometimes receive special treatment.
That is part of the spirit of the project.
Why I like this approach
What I find interesting is that this makes Japanese practice feel less like homework and more like participation.
Instead of waiting for a formal exercise, a learner begins watching the world around them and thinking:
What can I say here?
How do I describe this?
What do I want to do?
What do I want to ask?
That shift is important.
It means Japanese stops being just a subject to study and starts becoming a tool for interacting with a world.
This is also why I think the system works not only for a dedicated TRPG stream, but also for other games such as Minecraft and potentially many other live situations.
As long as there is a scene, there is something to describe.
As long as there is danger, curiosity, movement, or surprise, there is a chance to use Japanese.
Daily drill practice and subscriber support
There is also a second part to this system.
Right now, Twin-san has been doing daily Japanese drill practice and sending me images of his work.
I check them individually and score the sentences.
This kind of personal review takes time and attention, so this part is handled as a subscriber-supported feature rather than something open to everyone.
That helps keep the system sustainable.
The live Japanese Challenge remains a broader public-facing entry point, while daily personal correction stays in the more limited, higher-effort category.
In that sense, the system has two layers:
- live participation through Twitch
- deeper personal practice through ongoing direct review
I think this balance makes sense.
How points connect to the TRPG story
The most important part is that these points are not just abstract numbers.
They are meant to connect directly to the main TRPG story.
The idea is simple:
the more Japanese a player uses meaningfully, the more their character can grow.
At the moment, I am keeping the character system relatively simple.
A character begins with:
- HP: 12
And over time, character growth may affect things such as:
- Strength
- Intelligence
- Speed
- Luck
- Bond
HP can also increase later, especially in connection with Strength and Intelligence.
I do not want to overcomplicate the system too early, because too many moving parts can make the whole thing feel muddy.
At this stage, clarity is more important than complexity.
What matters is that the points earned through Japanese can later become meaningful advantages in the story.
That is where the fun begins.
Why “Bond” matters
One stat I especially wanted to include is Bond.
This project is not built around a lone player in a vacuum.
It is built around interaction:
- with NPCs
- with viewers
- with the live atmosphere of the stream
- with a wider community that supports the learning process
So Bond represents more than friendship in a generic RPG sense.
It reflects trust, support, connection, and community participation.
I think that fits this system much better than simply copying a standard RPG charisma stat.
More than words: learning flow and atmosphere
Another thing I care about is that language learning is never only about vocabulary.
In practice, it also includes timing, tone, and the flow of communication.
That is especially true in live interaction.
For that reason, I see this stream not only as a place to practice Japanese words and sentences, but also as a place to learn how communication works inside a real shared atmosphere.
That means the stream needs to remain a space where people can actually learn.
If someone repeatedly disrupts the environment, ignores the flow of the stream, or harms the experience for others, moderation action may be necessary.
That is not separate from the learning environment.
It is part of protecting it.
Why I want to develop this further
What started as a small practical way to score daily Japanese sentences has begun turning into something much larger:
a system where language practice, live participation, character growth, and story progression all support each other.
That is the part I find exciting.
A learner does not simply complete an exercise and move on.
They build something.
They build points.
They build confidence.
They build a character.
And eventually, they build a role inside a shared world.
That feels much more alive to me than a static worksheet.
For now, Twitch is the main place
So for the time being, this project is being developed on Twitch.
If you want to follow it, participate in it, or simply observe how it develops, that is the place to look.

I may later write more about the system here, and I may eventually adapt parts of it for other platforms.
But at this stage, the live version belongs there.
Final thought
The core idea is very simple:
use Japanese, earn points, grow through play.
That is all.
But sometimes simple ideas become interesting when they are given a world to live in.
This is one of those ideas.
