Salty is Spicy
We say Salty "塩辛い" in Japanese.
Almost everyone from the Kansai region says 辛い（からい）without 塩. I know this because I'm from Osaka.
In the Kanto region, It is said that people say ”しょっぱい”.
（I've never said the phrase=しょっぱい.）
We also say spicy 辛い.
I use the word to describe things like this gum.↓

I have a funny friend who sometimes says, "yugito, it's hot today. Do you have spicy wipes?"
（=辛いやつ持ってる？）
I can understand him.
I'll show you an example.
（１）うわ、からっ（か～ら）、これ塩入れ過ぎじゃない？
（２）このカレー辛いよ。
（３）このガムは辛いから、眠気が吹っ飛ぶよ。
