I will be going to osaka,kyoto, hakone and tokyo nxt week. From the news, I read that there is currently a typhoon in Tokyo. Is it a cause for concern?
It will be heading north over eastern Japan on Friday, so there is no cause concern whatsoever if you are not arriving until next week.
Is it possible to predict will there be any typhoon nxt week?
Did you not see the link posted earlier in this thread?
Nothing else on the horizon at the moment, but at this time of year, it would be wise to check the site again before you arrive.
