What it's like to review ramen professionally.

A former engineer, professional ramen reviewer Toshio Yamamoto has sampled more than 6,200 kinds of instant noodles.

“I haven’t found ramen that’s five stars yet. I’m still on the journey to find that,” he explains. “The noodles will need to be perfect. The soup will need to have great quality and the condiments perfectly balanced, with a nice harmony.”
