Stop looking behind the curtain!

>過去の太陽の観測結果を調べたところ、黒点の増減周期や磁場構造が、地球が寒冷期だった１７〜１８世紀と酷似していた。 In comparison to astrological observations done in the past, sunspot size observations and magnetic reorganizations indicate a status somewhat like the 17th and 18th centuries. That's the furthest the article goes in explanation of.

They did a lot of stuff in the Edo period.

Times were odd then. If you examine the ink prints from that time, several oddities are noteworthy.

1) Lots o’ demons. Yep, up to their eyebrows in demons of all varieties. Often recognizable because they had their tongues sticking out.

2) Enormous genitalia. Both men and women had genitals about 10 times larger than modern men and women. It is not known why.

3) Tea ceremonies. Often lasting for years, this was preferential as something, anything other than just listening to the continual rain.
