Library or study spot

I am looking for a place in Tokyo more in the Asakusa region where I can easily study for a whole day with WiFi and maybe outlets. The only thing I always see people suggesting is Starbucks and coffee shops, but they are always overfilled and I can never get a seat or if I am there early I have to contemplate between a study spot and getting to eat at least one meal a day. Are there maybe any university library’s or facilities that are technically free for anyone to use?
