The last week torrential rainfall in western and central Japan
was caused mainly by the seasonal rain front
(rather than the typhoon Prapiroon).
Depending on where your starting point is located,
you can take a domestic flight to Matsuyama Airport [MYJ].

Iyotetsu limousine buses and street cars are now available as usual.
Matsuyama Castle is scheduled
to be specially illuminated during the nighttime
from the evening of the 13th of July (yesterday)
until the middle of August.
The hot spring resort of Dogo Onsen seems not affected, either. Any problem in the transport (train) and visit the place?
On the JR-Shikoku route Kojima -- Matsuyama,
you have to take a substitute bus
between Motoyama and Kanonji Stations (in Kagawa Prefecture),
where the operation is expected be suspended for at least one month.
Also, in the middle of the route, trains are planned to go less frequently.
Shimanami Kaido's cycling route Onomichi -- Imabari
seems still in some trouble.
A few SNS comments suggest
that you have to make a detour in Mukaishima due to a landslide
and that you should be careful of gravel remaining on the cycling road.
Currently no typhoon is approaching Japan,
but it is likely to be sweltering hot during the daytime next week
in Honshu, Shikoku and Kyushu.
For the prevention of heatstroke,
you had better carry some sports drink with you.
