Domino Effect, Japan Edition (1858-1970's)

[IMAGE DESCRIPTION]
Japanese history version of the Domino Effect meme with 10 black dominoes from 2009's "World record for the largest domino toppled in a chain".
On the lower right is a hunched over male about to tip over the smallest domino (1st domino). On the upper left is the largest domino (10th domino), which is 8.8 times taller than the smallest.

Context:
Bonsai Pop's The Rurouni Kenshin Controversy video dropped yesterday and its timeline of Japan inspired a dominoes meme in me. Hours of my life wasted and here we are. 🤷🏿‍♂️
tl;dr about the Rurouni Kenshin controversy: Nobuhiro Watsuki (the mangaka) was convicted of and fined 200,000 yen for possessing "multiple DVDs with videos of nude girls in their early teens and other materials."

A more legitimate source for the 10th domino can be found on page 3 of 35 (Cute Handwriting and Slang) in the pdf scan of Chapter 6: Cuties in Japan by Sharon Kinsella in 1995's Women, Media and Consumption in Japan book.
