what kind of pass to buy

Hi there!

Shikoku is awesome, especially Takamatsu.
Now let's have a look at ticket prices and see if a JR Pass would be of help!

Osaka - Tokushima ¥ 8,130
Tokushima - Takamatsu ¥ 3,270
Takatamatsu - Matsuyama ¥ 6,210
Matsuyama - Kochi ¥ 10,380
Kochi - Takayama ¥ 19,330
Takayama - Osaka ¥ 10,610

That's a total of ¥ 57,930 or ¥ 12,830 in savings! with the 14 day JR Pass (45,100yen). The JR Pass is also valid for local travel within Osaka on JR lines and you could possibly also use it to travel to the airport, making even better savings!

Hope this helps!
