Thanks you for your remarks

2- Koyasan

For the full enjoyment of Koyasan, I recommend to stay overnight.

3 Matsumoto + ( Nagano ? ) + stop Narai
3 nights Hiroshima

You will be spending a lot of time on trains on this day. You won't be left with a lot of time for Matsumoto and Narai. Nagano is impossible.

3 Hagi visit with bike
2 nights Matsue
1 stop Tsuwano visit with bike

For efficient travel, you should travel as follows:
Hiroshima - (train and bus) - Hagi - (bus) - Tsuwano - (train) - Matsue

2 sunrise Izumo

Don't use the Surise Izumo for travel between Matsue and Okayama! Use a regular limited express instead. By the way, Bitchu-Takahashi is along the way.

thanks uji ,
Ok i do'nt go to nagano

I go to hagi by train to shin-yamaguchi and then jr bus to hagi .

but i return to hiroshima because I do'nt find

And for Kyoto what do you propose the 7th day

Thanks very much for your answers
