The March issue of the 2019 Genba Newsletter summarizes information about Tsushima and Iki.
On February 12th and 13th, we planted cherry blossom trees in a park near the site of the slope shaft in Tsushima.
On February 26th and 27th, weeding and felling bamboo was carried out around the Iki entrance to the inclined shaft.
I am summarizing.
Please see the March issue of Genba Newsletter for details.
