A small public marker indicating the 140°E meridian — a neat geometrical subject amid suburban Kamagaya. Photograph the plaque, marker line and surrounding streetscape to show human scale and the concept of a longitude line. Easy, free access from local streets or Shinkamagaya station; no entry fee. Visit at golden hour or overcast midday for even light. Weekdays are quieter; parking limited to nearby paid lots. Cultural note: a subtle scientific landmark popular with locals and geography fans.
