Light, refreshing with a satisfying crunch - Japanese Cucumber Salad (Sunomono) is the perfect side dish for all of your favorite Japanese dishes! You only need 6 ingredients and 15 minutes to toss this together!
Thinly slice cucumbers with a knife or mandolin so they are 2-3 cm thick. Place the cucumbers in a large bowl and mix with kosher salt and rest for 5 minutes to let the excess water release from the cucumbers.
Squeeze out the cucumbers to remove excess water, then rinse off the excess salt with cold water and squeeze the cucumbers until dry. Place on a paper towel to pat dry.
In a small bowl, mix together rice vinegar, sugar, and soy sauce. This is the cucumber dressing.
Add the dressing to the cucumber, add sesame seeds, and mix well. Serve immediately and enjoy!

Notes
cucumbers - I recommend using Japanese or Persian cucumbers - both are small, with a thin skin, few seeds, and less water, which makes them ideal for cucumber salads. Do not use American cucumbers - they have seeds and their skin is too thick and waxy.
kosher salt - if you don't have kosher salt or another larger grain salt on hand (like sea salt), you can use table salt but 1/2 of the amount. Table salt has a higher salt content than kosher salt, so it is not a 1:1 substitute.
rice vinegar - if you don't have rice vinegar on hand, you can substitute with apple cidar vinegar.
Practice safety and use the mandolin guard that comes with it!Remove as much moisture as possible from the cucumbers - we do this by salting them and then squeezing them gently after rinsing the salt off with water. Excess moisture will result in a watery cucumber salad.Storage - Store any leftover Japanese Cucumber Salad (Sunomono) in an airtight container in the refrigerator for up to 3 days. You may notice the cucumbers releasing more moisture as it sits in the refrigerator - this is normal! However, I don't personally prefer eating the cucumbers after 2ish days, as I find the salad becomes soggy and the dressing becomes diluted!
