This place is Muslim owned and run.
The wasabi is actual wasabi root, and the soy sauce is home made (to ensure it's 100% halal)

And the quality and authenticity is mind blowing, this little family run business can put all the Japanese restaurants in Singapore and Johor to shame.

The only way to beat this is to actually go to Japan and find the best places for yakiniku and sashimi, THE BEST PLACES, NOT JUST ANY PLACE.
