On Sundays, Japan’s largest morning market appears on a wide quay, like runways, where I really went except Sunday but no one was there.
Most of the things sold at the morning market are local seafood, vegetables, and prepared foods, but here you can find toys, DIY, sewing corners, fishing gear and much more.
I wonder why they handle such things, but in short, it makes sense to think of it as a festival venue in the countryside. Anyway, it is in a chaotic state.  Feel this energy !
Furthermore, since the morning market is held before dawn, everyone procures breakfast here. It is also pure to close one after another after eight o’clock.
Even if you miss the morning market(Tatehana-Ganpeki) on Sunday, you can enjoy it here because another morning market is held every day in front of the station. There is a table where you can gather your own food for 100 yen and eat breakfast.
Hachinohe Line
When you get on the Hachinohe Line, you can feel the endless beach and the blue forest (that is, the origin of Aomori).
