The NTT History Center of Technologies is basically a museum about the history of telecommunications in Japan. It's only two days a week (Thursdays and Fridays), from 1pm to 5pm. I wasn't sure what quite to expect from this.
So despite the fact we made really last minute reservations, the staff there were really nice and gave us the student tour, which meant we got to watch a video about how NTT envisions the future of telecommunications will be like, and a guided tour by a OB supporter. An OB supporter is basically a worker from NTT who has retired, and thus, has a lot of insider knowledge about how things work.
If you can read Japanese, here's more information about it.
The next day, we went to ICPC at Musashi University.
Basically, we listened to three panels: One on privacy, one on drones, and one on internet and the culture of cities. For some reason, I found the first speakers of the first two panels to be speaking really fast, and didn't really catch what they said.
In between panels, someone flew a drone!
The drone was really noisy though, and it seemed hard to control.
So, that's about it I guess. It felt like a pretty long trip, and we definitely crammed a lot of activities into it. And now, to study!
