It's hard to give such feedback. Assuming it didn't rain last year June, doesn't mean it won't rain this year.
In fact, this is something you can Google, ie. weather forecast, other than Japan-Guide site. If you want even more info, Google for the weather of June 2015, June 2016, June 2017 and predictions for 2018. Then analyze yourself and see if it's likely to rain.
Haha, I think my question a bit dumb, btw thanks for the advice.

yes, rainy season on June
June is low season, airlines will have promotion on that period
example airasia last year osaka promotion for June, RM257 for return flight

That, super cheap !! hope can get a deal this year...
I guess have to plan an itinerary that have more indoor activity or delay the trip... but don't want to go on Summer because is sooo hot, cant enjoy
