Japanese festival food: the long potato

There are lots of different food options at Japanese festivals. Within the vegetable category, the potato is probably the biggest star!  There are dozens of different potato based Japanese festival food options. In this post: the long potato (fry / chip).

 As the name suggests, the long potato is a festival food where the potato is served long. It is a type of french fry or chips. That is, potato that is deep fried. I don't know if they source a long potato for this popular festival food, or if there is a way to cut a potato to make it longer? If you know, please do share the answer in comments. What I do know is that it can be delicious. 

However, the long potatoes pictured in this post weren't particularly good. I don't think they were fried for long enough, so they weren't crispy. Moreover, they broke easily. We lost several long potato fries to the ground because they broke when we picked them up from the tray. But they were quite filling despite that! 

That is the second time I've gotten long potato fries that weren't particularly good at a festival, so I don't think I will be ordering them again. But they are obviously very popular as there is always a 'long' queue at the food trucks that sell them. Have you had long potato (fries) at a festival before? What did you think?
