I'm in a NRT airport hotel now (almost 8 am) after having arrived here in NRT yesterday evening. The typhoon is the top story on all the news channels.

According to the news right now, the typhoon is due to reach landfall around or to the east of Nagoya (which itself is east of Osaka) this afternoon, and then curve around to the right to hit Tokyo. As this is a slow moving typhoon, the news says that we can expect to have about 15 hours of high wind and rain (from this afternoon to tomorrow morning). The news further reports that several domestic flights have already been cancelled, and that more cancellations and delays can be expected (depending on the path the typhoon takes).
