Again, this page is under construction. Please leave the body of it alone until I have finished. Thanks. :-) If you somehow find this page I would welcome comments and suggestions while I am working, although I want to reserve the right to remove them before I post this page.


This Joseki is rather unique, as it is primarily played only with the SanRenSei opening. It was developed by Takemiya Masaki and it's primary aim is to develop powerful Thickness towards the center.

Diag.: Takemiya's Kosumi Basic Diagram

At first glance this move looks slow and cumbersome and doesn't appear to apply much pressure one white. It was these properties that first led me to take a look at this move in more detail. After all Shusaku's Kosumi has been considered to be too steady for modern play. Yet Takemiya's kosumi is a modern invention, so it must have taken into account recent lines of play?

There are several ways of continuing from here. A common response is for white to jump into the corner with 'a'. Being that the kosumi does not apply as much pressure to white as something like a pincer, white will often play a tenuki. The most common one is the other approach at 'b'. Occasionally white will want to counter black's influence with something like the keima of 'c'.

  • Takemiya's Kosumi Corner Invasion - Look here for continuations from 'a'.
  • Takemiya's Kosumi Tenuki? - Look here for continuations after white does not respond to the kosumi locally.
  • Takemiya's Double Kosumi? - Look here for continuations arising from playing kosumi in response to the second approach at 'b'.
  • Takemiya's Kosumi Random? - Look here for random other responses such as white 'c'.
