Leave all the messages for the future⋯ Hamasen is one of the first modernization regions. Since the Japanese colonization era, there had been many scenic postcards recording images of Hamasen. Some of the architectures still remained in the same places as they had been in the postcards. Over hundreds of years, this piece of reclaimed land carries memories of fishing men, customs declarers, and local elders from generations to generations. Sceneries in people's memories intertwine with different time layers of maps of Hamasen. What kinds of messages do we intend to leave for the next generation?
