Somewhere Among takes place in Japan 2001. Anniversaries, holidays, solstices, and historical events that Japan and the United States share were woven throughout the story. For verification and further study, I have included links to English sources. Links to other sources are included in each post on this website.
It is important to note that Sea Day and Respect for the Aged Day now fall on the third Monday of July and September respectively. That was not the case in 2001. Also note that moon-viewing is traditionally mid-September but it depends on the year Check here for the holiday calendar for 2001.
Space/moon data and weather charts for west Tokyo were used as reference for the scenes.
