In April, the city issued an official ordinance asking visitors not to eat while walking.
One major concern is trash from packaging and leftover food, which can attract animals and make a mess that locals will have to clean up.
Kamakura is about 30 km (19 miles) southwest of Yokohama. It's home to some of the country's best-known temples, as well as for gorgeous beaches.
A representative from Kamakura city told CNN that the ordinance -- which is posted in public areas -- was created to build awareness of the issue rather than to penalize travelers. There are no fines or citations for people who violate the request.

In particular, Komachi-dori, a busy street with lots of shops, has been a focus of attention when it comes to eating outside.
The street is a stop on many local food tours, despite also being a commercial area.
However, concerns about eating while walking aren't just related to potential spills and messy clothes.
Many Japanese people believe it is poor manners to walk or do other physical activities while eating because it means you're not appreciating your food properly. For some, this belief has its roots in World War II, when food was scarce and it was something to be treasured, not treated casually.
The issue of tourists eating in the street isn't a concern isolated to Japan.
In Florence's case, the restrictions come with steep penalties -- namely, a €500 ($581) fine.
Some locals want restrictions or even closures because of the ever-growing crowds of people, but others believe there can be a happy medium between a vibrant street vendor culture and not getting in the way of everyday life, such as blocking of traffic lanes.
