SawanoTsuyu is the name of candy that has been made by a small shop in Otaru since 1911.
The unique characteristic of Swanotsuyu is that it is made by sugar only. No other ingredients and additives are used except for a little flavor of citrus. Therefore, it is neither too sweet nor having a strong aftertaste.
There are many nice sweets from Otaru. Sawanotsuyu is a low-key, but has been a popular candy for such a long time.
The shop is also located on a modest scale near Sushiya-dori street.
