I am traveling to Tokyo during the first week of September. I am assuming from what I have read on the Internet sites that the temperature should be in the low 70s? Should I take an umbrella along?

not sure where you received the information, but the first--and last--time i traveled to tokyo early september the weather was high 80s/low 90s with high humidity.

i was told it doesn't begin to cool down until late september. i usually visit in october for this reason

Oh well. That's the only time I could travel in fall. Thanks for the info.

Early September can be pretty hot. Mid 90's is not out of the question.

It is also at the tail end of the typhoon season, so potential for heavy rains. I second the high humidity and temperature.

Weather forecast for Tokyo in September is very much like the weather forecast Robin Williams gave in "Good Morning Vietnam". And even worse in August.

I always believe everything I read on the Internet. Low 70s? Maybe Celsius!

Summer in Japan/Tokyo is July-August-September. Figure that you are going to Washington DC in August and that's what September is like in Tokyo.

Average high temperature of Tokyo during September is 81 F, and average low temperature of Tokyo during September is 70 F. Due to humidity in Japan temperature may feel hotter if you are not used to in humid climate. Also there is temperature difference between night and day. Obviously, beginning of September temperature is higher and end of September temperature is lower.

By the way, average temperature (average between low and high) of Tokyo during September is 75 F. These are measured between 1981-2010 by Japanese weather service.

Well, I guess this means I will be spending a considerable amount of time indoors in department stores and museums during the day and venturing outside in the evening.

Sounds like a plan (pretty much like my plan ). If you're traveling from the United States - you will probably be up very early in the morning. So doing things outside then will probably be ok (assuming you're ok with temps in the high 70's and high humidity in a city - I'm ok with that at home in Florida - but I don't live in a big city).

Here's a list of museums to start on:

And don't forget the food basements in the department stores!

Hot with a chance of typhooons.

I do not think you have to worry a lot about typhoon. For those of you do not know, if it originates in Atlantic Ocean then it is called hurricane, if it originates in Pacific Ocean then it is called typhoon.

Again, average taken from Japanese national weather center:
Average number of typhoon in month of September: 4.8
Average number of typhoon came close to shore of Japan that weather warning was issued in month September: 1.5
Average number of typhoon which made landfall in Japan in month September: 0.8

Enjoy your stay in Tokyo during September.

Well, we will see. Everyone recommends visiting Tokyo either in October or April-May, but my scheduled does not allow it. I guess I have to make the best of it. Another site that has some useful information about what to expect in September:
