There are many Japanese “summer foods” such as the classic, watermelon, or cold noodles known as “somen,” or fried eggplants drowned in a dashi.
But my favorite summer food, hands down, would have to be the humble shaved ice, or “kakigori.”
Describing kakigori as a snow-cone or the like is a disgrace to kakigori. When you get down to it, it is an extremely simple combo of crushed ice + flavored syrup. It is because it is so simple, getting it right can be likened to an art (maybe I am building it up too much, but it is awesome).
Kakigori is extremely easy to find because there is a fixed symbol for it:

It usually is represented by a red character for “ice” with tumultuous blue waves underneath.
(kakigori is so delicious that even the ocean tries to reach up and taste it <- this is one interpretation I thought of now)
ASAMIREIZO
For serious connoisseurs of kakigori ONLY. A 3 hour wait would not be completely surprising. This store prides itself on using local, natural spring water for its ice. There is also an art gallery attached.

MIKAZUKIHYOKA
This kakigori is layered thin slices, making it a little bit of a different texture than most shaved ices. This shop likes to use real fruit along with its syrups. This place also has monster-sized pancakes.

HIMITSUDO
Himitsudo is far from a “himitsu” (secret). It is a wildly popular Tokyo kakigori shop. They serve up seasonal flavors with a main focus on fruit. Expect to wait in a line for a while.

CHIMOTO
You might walk by Chimoto without noticing it because of its traditional, understated design. But if you walk on by you would be missing out on classic Japanese kakigori that is bursting with Japanese traditional ingredients like sweet beans and kanten (known as agar-agar. People might be familiar with it as the gel you use in a petri dish. It can be people food as well as bacteria food!)
