Value
At minimum, it is impossible to score this yaku without at least either toitoi or chiitoitsu. So, this yaku is actually at minimum, the equivalent of 4 han.
When factoring fu, the combination of ankou and minkou (closed and open triplets) produces a fu count of higher than 10. The lowest possible fu is generated with 4 minkou, leading to hadaka tanki (lone pair wait). Adding the base 20 fu for any hand, this yaku is guaranteed greater than 30 fu; and with the rules of fu, that number is actually rounded up to at least 40 fu. So, at minimum, honroutou is at minimum at mangan.
Example:
Agari:
This is the lowest possible honroutou, if not played in the West round. For each of the open calls, they are worth 4 fu. In combination, they add up to 16 fu. Then add the tanki (pair wait) for 2 fu. In total, this hand has 18 fu, in addition to the base 20 fu; and that makes 38 fu. Per the scoring rules, the number is rounded up to 40 fu. With a minimum of 4 han and 40 fu, this hand is guaranteed at least mangan.
