In English-speaking world, there are more than 1 awards for gay porn, e.g. GayVN or a few others that I've seen before but can't call the name now.
Besides, there are some awards for Japanese straight porn, e.g. AV GrandPrix or Sky PerfecTV! Adult Broadcasting Awards.
However, are there any awards for Japanese gay porn?
PS: Any, hosted by pro or fans, online or offline, are both fine. A general award including a specific sub award for Japanese gay porn is also fine (e.g. Oscar is mainly for the US film industry, however it also has sub award like Best International Feature Film for international films)
