100-page Annual Securities Report, in 3 lines first. How to use Kabuyomi's 'AI Summary'
You find a company you're interested in and open its Annual Securities Report (Yukashoken Hokokusho). But it's over 100 pages long. With information densely packed on business descriptions, risks, executive compensation, and more, have you ever quietly closed the tab before reaching the crucial part—'So, what actually happened with this company this term?' Today, I'd like to introduce Kabuyomi's 'AI Summary,' which lets you receive that thick report in 'just 3 lines' first.
What you'll learn in this article
How 'AI Summary' condenses the key points of this term's report into 3 lines plus body text
How to use those 3 lines (the reading order), using the Mitsubishi Corporation page as an example

What is 'AI Summary'?
It is a section within Kabuyomi's stock pages where AI compresses reports that exceed dozens to 100 pages into '3 lines + body text.' In addition to the 3-line summary, perspectives such as risks, dividends, and financial health checks are organized. Before chasing fine details, you can grasp the overall picture in a few seconds—that is its role.
(Terminology note: Annual Securities Report = Yukashoken Hokokusho. It is the most detailed official report issued once a year by listed companies, containing everything from business content to risks and employee numbers.)
Know 'What happened this term?' first
When you start reading about individual stocks, the biggest problem is actually not the difficulty of analysis, but that it is 'too long to grasp the overall picture.' If you read from the beginning, you run out of steam on the detailed descriptions early on and never reach the crucial 'changes of this term.'
'AI Summary' reverses that order. You first grasp 'roughly what happened' in 3 lines, and then read only the parts you are interested in more closely. Since you have the map in hand before you start walking, you are less likely to get lost in the sea of text.
Following along with Mitsubishi Corporation
The example we will choose is Mitsubishi Corporation, a name everyone knows. Mitsubishi Corporation is a 'general trading company'—a company that handles a very wide range of businesses, from resources and energy to machinery, food, and daily life. Honestly, it is the type of company that is difficult to explain in one word. That is precisely why it is a subject where the value of '3 lines first' is easy to understand.
When you open the stock page, the key points of this term's report are summarized in 3 lines in the 'AI Summary' section. The reading order looks something like this:
First, grasp the overall picture of this term in 3 lines
If there is a point that interests you, check it in the body text below (a slightly more detailed summary)
If you want to know more deeply, return to the original text on EDINET with one click and check that specific part in the original source
For unfamiliar terms that appear in the summary, you can tap the words with dotted lines to open an explanation on the spot. Please check the Kabuyomi screen to see what is actually written in the 3 lines. The important thing is that you can change the order from 'reading 100 pages from the beginning' to 'targeting and reading after getting a lead in 3 lines.'
You can also read it this way
One way is to compare. If you open the same 'AI Summary' for the 8 companies available for free (Toyota, Sony, Mitsubishi Corporation, etc.), you can see the differences in 'what each company highlights as key points.' When the business models differ, the points that emerge in the 3 lines also change.
Another way is to use it as a shortcut to the original text. By getting a feel for the content through the 3 lines and the main text, you can go straight to the specific point you want to verify with your own eyes from the original EDINET document, without having to read the 100 pages from start to finish. Since the summary is automatically generated by AI, it is safe to use it as an entry point, provided you always verify it against the original text at the end.
(The same stock page also features functions to view differences from the previous year or changes over 10 years. This is your entry point when you want to further track changes that caught your interest in the 3 lines over a chronological timeline.)
