Please let me know how can I go to Achi Village from Matsumoto train station.
To reach Achi Village from Matsumoto Station, first take the Chuo Line train from Matsumoto to Okaya Station. Then, change to the Iida Line and take the train all the way to Iida Station. You can take the Hirugami Line bus from there to Achi Village.
You may want to use the Hyperdia website to plan your train times.
I hope that answers your question!
