My suggestions
: Unless you add distant destinations,
you donft purchase a Japan Rail Pass for this journey.
: You choose accommodation for which the host will accept cancelation without a charge a few days before the check-in day.
: Before you finalize your application for a domestic flight,
when your Kansai trips draw near within 7 days,
you check weather information by Japan Meteorological Agency.

A Japan Rail Pass (7-day), even if it pays off,
would not save greatly your cost.
For you to travel by JR
from Tokyo via Shin-Osaka and Osaka to Nara
then back to Tokyo
within 10 calendar days,
with your seats reserved in Shinkansen Hikari trains,
the regular cost is 27660 to 28460 yen (depending on dates),
after a 10 percent round-trip discount on the basic fares.
A 7-day Ordinary-Class Japan Rail Pass
is sold at 29110 yen,
which is paid in your currency.
You should pay also a handling fee to the sales agency.
Depending on the location of the sales office,
transportation fees are necessary to get your Exchange Order.
(To make a 7-day JRP cover your Tokyo Monorail train ride,
you have to shift your Kansai trips to earlier or later days.)
When you go with JR regular tickets,
you can pay 310 yen more
and take a Shinkansen Nozomi train to or from Kyoto or Shin-Osaka,
which a Japan Rail Pass does not allow you.
(On the Tokyo Shinkansen, compared to Hikari trains,
Nozomi trains are much more frequently available.)
if i take plane from haneda to osaka, are that cheaper than use Shinkansen? Well,
to foreign visitors,
ANA and JAL now offer big discounts on domestic flight fees;
therefore your cost on Tokyo -- Osaka -- Nara part can be a little lower
compared to when you take a Shinkansen train,
by about 2000 yen, I suppose.
- Discount air tickets
https://www.japan-guide.com/e/e2364.htmlYou might have a chance
to fly by Peach Aviation or Jetstar at a low price,
but flights by these two companies connect
Narita Airport (located actually outside Tokyo)
and Kansai Airport.
(Regrading specially low-price flights,
I recommend you check possible limitations.)
- How to travel between Tokyo and Osaka
https://www.japan-guide.com/e/e4006.htmlAnyway,
you had better consider the possibility
for your train | flight canceled because of bad weather conditions.
Due to the typhoon Jebi,
flights scheduled for September 4 between Haneda and Itami
were mostly canceled.
Winds and rainfall by this typhoon
forced Kansai Airport be isolated on the sea.
Strong winds by this typhoon
also affected the Tokaido Shinkansen,
making the operation wholly suspended.
i arrive at Haneda airport and go to Tokyo You will be already in Tokyo at your arrival.
Haneda Airport is located in Tokyofs urban area.
