I’m travelling next week from Nagoya to Nakatsugawa and I’m not sure if JR Chuo line is working after recent floods. Anybody knows?

The JR Chuo line is operating as usual. Trains in Eastern Nagano have not been adversely affected by flooding. To see up-to-date information about train operation and delays, see the JR East and JR Central websites.
I hope that answers your question. Have a safe trip!
