3S Ranking Battles (Like Virtua Fighter rankings), where/how?

I am trying to get info on how to enter those ranbats. I visited the Japanese pages, but I don’t know which pages show the dates when they are running the next one.

I am close to Fukuoka and want to enter one, someone please help me. I am going to Fukuoka on Friday to go to Monkey House but would like to know when exactly they do these.

I can’t speak enough Japanese to ask them the dates, but I know I could definitely enter the tournaments because they use a mostly hiragana/katakana chart when starting them, but would like to know any sites and so on, thanks.
