Ōsaka’s Megaliths

The Tako-ishi, Ōsaka castle's largest stone (by surface area.)
The castle of Ōsaka is an absolute must-visit for anyone coming to Japan. While lacking the obvious elegance of Himeji castle, Ōsaka is mesmerising with its river-wide moats and the gently curved & towering stone foundations. Complementing all of this are nine buildings that at least saw the close of the Edo period (1603 – 1868). To have even as few as that is a rarity.
It’s those walls though, that are the real standouts for me. Of what must be thousands upon thousands of stones, there are eleven that are of particular note due to their epic size. They are Ōsaka’s Kyoseki (巨石), literally giant stones, the smallest of which is estimated to weigh over 40 tons.
All 11 stones were located at one of three entrances, the Sakura Gate, the Kyōbashi Gate or the Ōte Gate. Each of these gates is (or was) a Masugata-style gate (a box-like set-up with one small & one large gate creating a path through two of the box’s four walls.) Why at entrances? That’s were they’ll be seen, of course.

The Higo-ishi, Ōsaka castle
The construction of the Tokugawa citadel was indeed a mammoth task, and for the Daimyo involved, an expensive one. Each Daimyo was expected to supply materials & labour for their allotted section of the castle. The Tokugawa regime was able get their fortress built, and at the same time, drain the finances of any potential adversary. Hmmm…. clever.
Of all the Daimyo it seems it was the Ikeda of Okayama who thought that bigger is better. All but three stones, not those in the Ōte-Mon entrance, were supplied by Ikeda Tadakatsu.
The other big-rock-lugging Daimyo was Katō Tadahiro of Kumamoto, A guy whose mighty big-rock-lugging efforts weren’t enough to keep him in favour with the Tokugawa. He was dispossessed of his domain 12 or so years later.
Below is a table detailing the various facts and figures relating to each stone. You’d probably best take all figures as approximate. Also, check the notes below the table for further clarifications.
