Digimon Adventure: Last Evolution Kizuna - Feb 21, 2020
Just in case anyone is wondering (soft spoilers):
At the end of Kizuna, Taichi submits his thesis proposal and we can see the name of the uni he is attending: Soumei Uni (thanks to @kazarinn for the translations). Waseda University is abbreviated as Soudai (like Tokyo Uni as Todai or Kyoto Uni as Kyodai), so I did some research on google maps and voilà!
Waseda University, Nishiwaseda Campus, Faculty of Political Science and Economics, Shinjuku, Tokyo
The faculty Yamato is attending was a little more tricky to find, but I finally found it with the info provided in the novels and google images.
Keio University, Yagami Campus (oh, the irony), Faculty and Graduate School of Science and Technology, Kohoku, Yokohama
Nice scouting! This definitely explains why Yamato took Gabumon to Yokohama at the end of the movie – it’s close to his uni, after all. (Also, given that it seems Yamato still lives in Tokyo, it’s very fortunate that he’s a biker…)
Taichi’s uni being in Shinjuku also explains a lot as to the circumstances of his running around at the beginning of the movie, and why he and Yamato also meet at a restaurant in Asagaya. Incidentally, that’s also a real place – the Buchi Asagaya Shop (ぶち阿佐ヶ谷店). The exterior is actually entirely unaltered, and, amusingly, according to the BD commentary, the actual shop advertises that they were used in Kizuna, so it seems to have been a mutually beneficial agreement.
According to wiki, Waseda and Keio are equally prestigious and are considered rival universities. Another reason why it’s perfect that Taichi and Yamato are there :)
