not sure if kogasa is referencing anything special straight from the wiki
The Kurobe Dam is the most popular hydropower site in Japan[1] and, between late June and mid-October, water is released from its spillway for onlookers. The surrounding Kurobe Gorge is also popular as well and is accessible by the Kurobe Gorge Railway.[6] A novel turned film, Kurobe no Taiyō (黒部の太陽; literally "The Sun of Kurobe"), starring Yujiro Ishihara (the late brother of Tokyo governor Shintaro Ishihara), recounts the drama of the project. In addition, the film "Project X" was also based on the dam's construction
may be a refence to the novel but doubt it. could just be that kogasa/author loves water?
Wikipedia says that the song referenced in the title, "Earthly Stars", was performed by the artist at Kurobe Dam during a music show. Maybe he just really digs the song and wants to visit the place the singer was at.
Darth_Sirov said: So far, only thing I know about it is it is the highest dam in Japan... unless the flow of water through it is to be some form of metaphor.
It could be he just thinks it's cool/impressive/potentially romantic. People make trips to see Niagra Falls for touristy or romantic getaways, and it's basically just water going over a cliff on a really, really grand scale.
Too bad he didn't actually propose when they went to Kurobe Dam.
Uh-huh...N-...no, that's not it!!It's great that father Kanako approves of our marriage, isn't it?What's up with that response?Earthly StarsI don't get what you mean.Crack SnapCrick PopOh? Where?Dissatisfied about something?Kurobe Dam.
