~About Kotsu-Azu Railway Channel~
Kotsu-Azu Railway Channel is a channel that delves into railways from various angles, such as routes, vehicles, and types, focusing on railways in metropolitan areas.
For more than 10 years, I've been fond of railways, mainly commuter trains, and I've been creating various videos based on that, and thanks to you I was able to grow to the current size.
The owner's hobbies include trains and games. Although he is not a professional gamer, he has recorded top rankings in games, and is currently dedicating his passion to this channel. I would be happy if you could subscribe to the channel.
