I've been twice since 2018, and can't wait to go again.
Akihabara is easy. just walk in to businesses, anime merch is everywhere. If you can't find it there, it doesn't exist.
If you liked Hikaru no Go. you could go to the Nihon Ki-in. It was really cool, and there's a museum in the basement. They even let me sit in the Champion room.
There is a lot that goes in to sound engineering in order to make a movie going experience really good. Basically the sound is engineered to sound really good on the 100ish channels that movie theaters have, but when going to a home they have to crunch all that down to work with a 2.1 or 5.1 etc and there is inevitably loss due to overlapping frequencies and even immersive aspects. How can a voice seem to be as loud as an explosion for example.
On top of those difficulties you have directors like Christopher Nolan who has said that he doesn’t care about home audio and that his movies are made to be seen in a theater.
Is Clementine being developed again? I thought it was abandonware
