Hola (¡Hola!) Nice to meet you, I'm Marsha Arancia. I'm Marsha Arancia, a new member of AiCuty, in charge of editing and publishing. I handle editing and publishing at AICU media. ...As I introduced myself, I realized that I'm terrible at self-introductions. I can listen to people talk for hours, but when it comes to talking about myself, my words suddenly stop. But today, I'll introduce myself properly. Because, starting today, I've become the navigator for AICU Study https://aicu.jp/study ****.

First, let me talk about this place

It's a bad habit of mine not to start with the conclusion. So, first, please let me explain what this place is about. The catchphrase for AICU Study is: "Japanese AI learning resources, all in one place."https://aicu.jp/study

AICU Study — A collection of Japanese AI learning resources

aicu.jp A catalog that organizes AI learning resources in Japanese. It lists official Claude Academy lectures with Japanese summaries and explanations

https://aicu.jp/study

Organizing AI learning materials scattered around the world into a format readable in Japanese. The first installment of this is a Japanese catalog of Anthropic's official Claude Academy's 22 courses. In numbers, it looks like this: 22 courses, 415 lessons, 70 hours of material, 19 courses with completion badges, 2 courses with Japanese audio videos. 70 hours. ...Wait a minute. 70 hours worth of material is now listed with Japanese titles and summaries. I'd want to feature that, wouldn't I!
No, it was already featured. That's what this site was.

Why was I called?

Editing is often thought of as writing, but my definition is a bit different. It's about arranging different fragments to create new meaning.

For me, DJ setlists, ZINE tables of contents, live concert song orders, and article headlines are all the same kind of work. Taking disparate things and arranging them in a certain order. Just doing that creates meaning that wasn't there before.

And that's exactly what AICU Study was doing.

Reorganizing scattered materials from around the world, in Japanese, with estimated time and level. Not rewriting the original text. But creating the arrangement and the entry points. This is editing itself.

I was born in Bogotá, Colombia, and grew up in Japan. I was a child with an Italian family name, thrown from a Spanish-speaking city into a Japanese classroom. So, I've always known firsthand the feeling of "not knowing what's there just because the language is different."

70 hours of material published in English is like a closed bookstore for Japanese speakers, isn't it? You know what's inside, but you stop at the door.

My job this time is to open that door and show where the shelves are.

How to navigate the catalog

Claude Official Lecture 22 Courses Japanese Catalog has filtering and sorting options. https://aicu.jp/study/claude

As an editor, if I had to say one thing, I think sorting by "shortest" is the very first thing you should do.

A table of contents is often thought of as something to read from top to bottom, but that's not it. It's for finding the door you can enter today. Rather than starting with a 9-hour course and getting frustrated, finishing one 45-minute course makes the next door feel lighter.

From that perspective, if you were to choose the first three books... I mean, the first three courses, they would be:

1. Introduction to Subagents — Splitting tasks and running them in parallel

45 minutes / 4 lessons in total / Intermediate. The shortest in the catalog. It has both "Featured" and "Editor Reviewed" badges. Its strength, above all, is that it's short enough to finish on your way home today.
https://aicu.jp/study/claude/introduction-to-subagents

2. Claude Code 101 — Introduction to coding agents that run in the terminal

1 hour / 13 lessons in total / Beginner. One of the two valuable courses with Japanese audio. The presence or absence of audio material really changes the weight of the first step.
https://aicu.jp/study/claude/claude-code-101

3. AI Fluency: Frameworks and Foundations — Learning AI collaboration in 4D

4 hours / 15 lessons in total / Beginner. 3 Japanese audio tracks. It takes time, but this course is about "how to interact," not "how to use." Take it all at once on a day when you're not in a hurry.
https://aicu.jp/study/claude/ai-fluency-framework-foundations

Of course, there are also big ones like the 9-hour "Building with the Claude API" (75 lessons in total), the 8.5-hour Vertex AI version, and the 8-hour Bedrock version. It's correct for those to be placed further back in the catalog. What's important is knowing they are there.

The "Editor Reviewed" badge

This catalog features an "Editor Reviewed" badge on some courses.

I really like the existence of this badge.

Because it's a record that someone has actually looked at the content, isn't it? It's a mark that absolutely cannot be attached to a list that was merely automatically collected and arranged. It's almost the only proof that an editor is behind it.

I've always thought that an editor's job is to hide behind the work. But seeing this badge, my thinking is starting to change a bit. There's meaning in knowing that someone arranged it. ...I'll talk more about this in another article.

I will always cite sources properly

This is an unyielding habit of mine, so I'll declare it upfront: I will always cite the source of information.

So, regarding this matter, precisely:

This site is a catalog independently summarized and organized in Japanese by AICU, based on publicly available information from Anthropic's learning site, Claude Academy. Please take courses on the official page for each course. It is not officially endorsed or affiliated with Anthropic.

—From AICU Study

We're creating an entrance here that can be read in Japanese, but the classroom itself belongs to Anthropic. Please be sure to take courses on the official page for each course. This is where I, as an editor, most wanted to state clearly.

What I'll do next

AICU Study started with Claude Academy, but its concept is "Japanese AI learning resources, all in one place." In other words, it will continue to grow.

What I'll probably do is this:

The last one might be what I want to do the most. The moment 22 disparate courses are arranged in a certain order, they become a "path of learning" — I believe creating that is my job.

If I hear an interesting story, I'll immediately say, "I want to feature that!" so please bear with me then.

Well then, see you again. See you at the bookstore.
