New Inohana Tunnel give faster access to Miyoshi!

December 15, 2020

Travel to/from northern Shikoku is now much quicker and smoother!

Opening on December 13, 2020 the New Inohana Tunnel gives a much better access option for those who are driving to/from points in northern Shikoku such as Kotohira, Zentsuji, and Takamatsu City.

Previously, when going to/from these northern points in Kagawa Prefecture, there were two main road options: either take the Expressway which not only costs money in tolls but is not a direct route so it doesn't really save any time; or take RT 32 south from Kotohira up and over the Inohana Pass (413m) which was full of steep climbs and hairpin turns, and not so fun especially if the weather was bad or if you were stuck behind a large truck.
But after years of construction, RT 32 now offers the "New Inohana Tunnel" (the old "Inohana Tunnel" is up on the mountain pass). This series of four tunnels is about 8km long, reduces driving time by about 10 minutes, and cuts the travel distance by almost 5km. The smooth ride has few turns and a gentle slope, so no worries about being stuck behind any huge vehicle moving slowly up the mountain. And you'll have no problems with weather or the road freezing either. The longest of the four tunnels is over 4km long and there is no toll fee needed. 
Of course, it is still possible to take the old route over the Inohana mountain pass which also goes past the entrance to Hashikura-ji Temple MAP. Even though the old route takes an extra 10 minutes to go between central Ikeda MAP  and northern Shikoku places like Kotohira MAP , this route has lots of awesome views of the mountains that are particularly beautiful in mid-April to early May when the verdant first leaves start appearing, or in mid-late November when the autumn leaves are changing. And now that most of the trucks will be taking the tunnel, there's no need to worry about getting stuck behind one (however local construction may still be happening so some trucks may still use this route). But, if the weather is bad or you are driving at night (or you just have a need for speed), do yourself a favor and be sure to take the New Inohana Tunnel!
