It has strict quality control, having passed multiple certifications(FDA,BRCGS, HALAL,etc) and being guaranteed by an advanced production line in terms of quality.

Koikuchi Shoyu vs. Chinese Dark Soy Sauce
Koikuchi Shoyu should not be treated as a direct equivalent of Chinese dark soy sauce.
Although both products can contribute darker color, their intended culinary applications and flavor profiles differ.
For Japanese-style recipes, Koikuchi Shoyu provides a more appropriate soy seasoning profile for sushi, ramen, simmered dishes, marinades and Japanese sauces.
For customers sourcing a Chinese-style dark soy sauce specifically for coloring and braising applications, Yinghok can evaluate other products from its Chinese Cooking Sauce range.
How To Use Koikuchi Shoyu (Non-Halal Version) ?
Koikuchi Shoyu can be directly used for dipping sashimi and sushi, or drizzling over dishes like cold tofu to enhance flavor. It is also suitable for marinating meat, stewing, stir-frying, and preparing hot/cold sauces such as teriyaki sauce. When using, pay attention to controlling the amount and balance the flavor by pairing with ingredients like mirin and dashi stock.

How to distinguish and use Koikuchi Shoyu and Usukuchi Shoyu?
Koikuchi Shoyu has a deep color and rich flavor, suitable for heavy seasoning scenarios like stews and teriyaki.
Usukuchi Shoyu has a light color and high saltiness, making it more suitable for steamed or boiled dishes to avoid overshadowing the natural color and taste of ingredients.
Can Koikuchi Shoyu be used in Chinese stir-fries? What's the difference from Chinese light soy sauce?
It can be used. Koikuchi Shoyu has a richer soy-based flavor, deeper color and stronger savory character, making it suitable for Japanese-style cooking and sauces. With a salty taste that carries a subtle sweetness, making it suitable for enhancing the flavor of Japanese-style fried noodles, teriyaki vegetables, etc.
Chinese light soy sauce offers a more direct umami taste and can be substituted at a 1:1 ratio, but the amount of sugar used should be reduced.
