Needing some clarification on working holiday visa application procedure

I'm looking for advice from anyone who has applied/currently on a working holiday visa in Japan from the UK. I have read through the embassy's website countless times and was looking for some further clarification on somethings.

The embassy says that from 1 April 6,000 working holiday visas are accepted. Does this mean that if I don't apply in April I will have a low likelihood of receiving one? I'd like to leave for Japan in August 2026 and am stressed that leaving it will result in not getting the visa due to the limited spots.

Obviously it's impossible to know, just wondering if people have any ideas/thoughts. Please be kind.
