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.   
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 [[koutsu|ankou]] and [[koutsu|minkou]] (closed and open triplets) produces a fu count of higher than 10.  The lowest possible fu is generated with 4 minkou, leading to [[tanki|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:
Example:
:{{#mjt:9s}} {{#mjt:1'11p999'm4'443'33z}}  Agari: {{#mjt:9s}}
:{{#mjt:9s}} {{#mjt:1'11p999'm4'443'33z}}  Agari: {{#mjt:9s}}


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|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.
This is the second 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|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.
 
 
The lowest scoring honroutou is a [[chiitoitsu]] won by ron without riichi or dora.
 
Example:
:{{#mjt:99m11p1199s22334z}}  Ron: {{#mjt:4z}}
 
This hand scores 4 han and 25 fu for 6400(9600) points.
