An interesting aspect of this deferred variation is that we can push back the date of the earliest occurrence of the Chinese fuseki to the 1933 Oteai. In other words, smack in the middle of the Shin Fuseki period.
This shape was played by Hashimoto Utaro against Mukai Kazuo. It seems to have been a solitary example, even though White won in a fascinating game where Black avoided for a long time approaching the lower left shimari. Hashimoto probably was "adapting to circumstances" here, rather than genuinely experimenting.
In any event, the next example, again a singleton, featured the future foreign minister, Chen Yi, in China in 1951. Chen's opponent was the master Guo Tisheng. Guo naturally

Even then it was more of a talking point than a fashion, and progress was inevitably blighted by the Cultural Revolution in 1966. But suddenly, in 1968, top Japanese professionals began playing it against each other. Takemiya Masaki also began playing the high version in 1970. Since then, the opening has become one of the most important ever, though the low version still has a big edge - played roughly twice as often as the high version. Kono Rin's comments on the latest variety relate (so far) only to the low version.
