How long aso mt. open again?

In the pass after eruption, how long when aso mt. open again?
I have plan go to kyushu on 28 april 2015.
Is it possible to aso crater ?


Thank you

Volcanic activity is very difficult to predict. And since last year's catastrophe at Mount Ondake, the meteorological agency is now probably more strict in downgrading the level.

I feel it is quite likely that the crater will still be off-limit in late April.

Well, you'll have to ask the volcano. I also doubt you'll be able to get to see it - it is prohibited to get within 1km of the crater.
This site has the updated info:

In any case, assume you can't and have a backup plan.

Thank you. : )))
