Constructed in 2009, Tetsujin stands at 18 meters tall and currently lives in Wakamatsu Park. If you want to visit too then get off at JR Shin-Nagata station . The monument will be there for eternity and costs nothing to view it.
Together with the Gundam, maybe these 1/1 scale machines are Japan's secret defense system? ^^;
Some retro Tetsujin below.
