Travelling though the river of time, and discovering the history of an old sugar factory. Walking on the shore trail left with traces of the previous sugar factory railway, we feel the historical atmosphere where the scenery of the circular trail surrounding the lake fascinatingly resembles a ring on lake telling us the history of the sugar factory. From the tour to Taichyu Factory of Teikoku Seitou K.K., I see not only the charm of vitality, also the complete history.
