Ikkoku Mairi tours, Shikoku henro

Hi,
I read about this thing ikkoku mairi, meaning you devide the henro pilgrimage into parts in a tour.

Are there any such tours still available? Are they Japanese only?

Yes just not everyday as travel tour
and No just some tours no tour guide or no speaking english tour guide with.
Search by "一国参り or 一国まいり(ikkoku mairi)" + "ツアー(tour)" on google.
A day trip bus tour[バスツアー] most convnient and cheap under 10000Y.
tour guide: 添乗員 + 同行(with)/なし(no)
昼食: lunch 付き(include)/なし(not)

But basically ikkoku mairi means not only tour package travel by travel agencies
just make 4 contries separating each.
愛媛 Ehime [伊予 Iyo], 香川 Kagawa [讃岐 Sanuki]
高知 kochi[土佐 Tosa], 徳島 Tokushima [阿波 Awa]
