~About Kotsuazu Railway Channel~
Kotsuazu Railway Channel is a channel that delves into railways from various angles, focusing on metropolitan railways, including routes, rolling stock, and train types.

I've loved railways, especially commuter trains, for over 10 years, and from there, I've created various videos, which have grown to their current size thanks to your support.

The channel owner's hobbies include railways and games. While not a professional gamer, I have achieved top ranks in games, and now I dedicate that passion to this channel. I'd be happy if you subscribed to my channel.
