Please tell me about the sales region of Yuraku Confectionery’s products.
Please check our "Sales Area Map" in the following link (https://www.yurakuseika.co.jp/lineup/area.html) as some products may be sold only in limited regions. There are certain stores and shops that do not handle our products. In case you cannot find our products in the store, kindly ask the store directly about the availability of products.
Can I visit and see your factory?
We have factories in Kodaira City in Tokyo, Toyohashi City in Aichi, and Sapporo City in Hokkaido, but none of them are equipped with a factory tour route for visitors.
For this reason, we do not allow the public to visit our factories. We are sorry about the inconvenience to those who wish to visit our factories and appreciate their understanding as well since it is a measure to ensure thorough product management in the factories.
The chocolate turned white, is it safe to eat it?
When chocolate is placed at a high temperature (28 degrees C or higher), the cocoa butter melts and rises to the surface, and then when it cools and hardens, it becomes white and powdery. This phenomenon is called “blooming” and is unique to chocolate. It is safe to eat, but the flavor may be inferior. To prevent blooming, store chocolate in a cool, dry place away from direct sunlight.
How should I store chocolate?
Avoid direct sunlight and places with high humidity, and store chocolate in a cool and dark place with good ventilation where the temperature is kept at 28 degrees C or less.
When storing chocolate in the refrigerator, the smell of other foods is easily transferred to it, so put it in plastic wrap or a tightly sealed bag, etc., and consume it as soon as possible after opening the package, regardless of a shelf life of the product.

Does Black Thunder use ingredients containing alcohol or of animal origin?
Black Thunder does not contain any animal-derived ingredients except for milk and does not contain alcohol either.

For details, please call the helpline provided in this page.
There was an individual package with no contents in the family series. Should I send the goods to your company?
If the amount of the purchased product meets the weight indicated on the back display, you do not need to send it.
The Family Series uses an automatic packaging machine to wrap products, and if there is a shortage of products flowing into the packaging machine, empty bags may be produced. The content is inspected again by an automatic inspection machine, and even if an empty bag is mixed in the outer bag, please be assured that there is no possibility that the content will be short of weight.
There were products that did not contain the standard number of pieces in a bag. May I return the product to your company as a defective product?
Since we control products based on their weights, the standard number of pieces is indicated only as a guide, and there is a possibility that the number of pieces in a bag will be short of the indicated standard number. Meanwhile, the product will be a non-conforming one if it does not meet the weight described on the back display. In case you find such a non-conformance in the product that you have bought, we would appreciate it if you could send it to us.
