Kenta san (Some of videos have English sustitles (not CC)/ increasing day by day)
He is a top bike Youtuber in Japan.
He travels all over Japan frequently.
His travel channel contains Bike information, Food, Sightseeing spot, casual chat and superb view in Japan.(mostly not typical "guide-book" view for tourists.)
Tom's cycling (no English subtitle)
This channel runs by TOMI and YOPI (They're husband and wife).
Unfortunately they don't have English subtitles on their videos but I think you can still enjoy their video without subtitles.
runtime[car camping] (Some of videos have English subtitles (not Auto))
He mainly posts videos on the theme of "staying in a car," which has many core fans.
Although the place is limited and small, it is an interesting glimpse into Japanese life.
