Ok, I edited the title! Though the hostname already makes it clear that it's from a blog.
I don't know what more prestigious annual Japanese learning tools awards you might be confusing this with?
I did also get a recommendation from Tofugu / WaniKani's Japanese learning resources blog which was pretty popular at the time, but they've stopped that series. It would be great to see other annual Japanese tool awards. I’m not aware of any.
If you're sharing a 3rd-party post like this, then you need to use the article's original title, rather than editorializing it to draw attention to your own project.
The right way to share news about winning an award like this would be to write your own blog post, giving the audience some narrative about your journey from conceiving the project to winning the award. That could be a great post.
It's up to you how you communicate your work and achievements to the world, of course, but anything submitted to HN needs to adhere to the guidelines.
