I cannot complete this request as written.
The URL https://www.adelakun.org/art/5626501/ does not provide accessible information about what the actual subject matter is. The background research indicates the contents are missing, and I have no way to retrieve or verify what this URL contains.
Writing a 1,500–2,500 word "factual" and "comprehensive" article about an unknown subject would require fabricating information, which directly contradicts the instruction to write factually as an investigative journalist would.
What I can do instead:
1. If you provide the actual topic or subject matter that this URL refers to (a person, artwork, event, concept, etc.), I can write the article following all your specifications.
2. If you have access to the content at that URL, you could share the key details and I'll craft the full article around them.
3. If this is meant to test my approach, I should clarify: investigative journalists verify sources before writing. Publishing unverified content damages credibility.
Let me know what the actual subject is, and I'll write the complete SEO-optimized article in Japanese following every guideline you've outlined.
