Any links to this article? Given the strategic transport requirements and the terrain Japan had to deal with in the Pacific their super-heavy tank efforts seem like quite the oddity to me. Does what little documentation that survived the war detail the intended purpose of these behemoths?

You forget the real target and prize: China.
 
Nothing in reality, but when did that ever stop military fantasists? To whit: the Maus, Ratte etc.
 
Please try translation. ;) L=10.1m, H=3.6m

1941年4月、旧陸軍が三菱重工に発注し、試作1号の車両部分が42年4月に初めて試運転された。機密保持のため「ミト車」(三菱重工)、「オイ車」(陸軍側)の名称のみが知られ、これまで詳しい形状や仕様は不明だった。

 図面や仕様書、試作車の報告書や作業日誌が近年、古書市場に出た。軍用車両の研究家で知られる精密模型メーカー「ファインモールド」(愛知県豊橋市)社長の鈴木邦宏さん(57)が入手し、復元模型づくりを進めている。

Iwill post other information when I get.

The O-I is also to be found beating up lower tier tanks in World of Tanks http://worldoftanks.com/encyclopedia/vehicles/japan/j23_mi_to/ (I hate the blasted things!)

Given its availability in-game, and the models shown, drawings have obviously been available for a while!
 
With regards as to the development of the O-I superheavy tank: http://sensha-manual.blogspot.com/2018/09/o-i-superheavy-tank-complete-history.html
 
The Sensha blog posted an update on the O-1 in 2020, this is discussing fictional variants, some of which had cropped up in World of Tanks. As is that games want the freelanced variants are presented as if they were historic projects, even if they were not.

The only real O-I is the one of the blueprints. All other variants, including those in World of Tanks, are misinterpretations from a period when the blueprints were not know yet.
 
I must wonder if they'd intended these to drive in a straight line across China until they reached the mountains. As seems to have neither w-i-d-e tracks nor the US' T95 / T28 outriggers, probable soft-ground issues....

Suppose is another of the 'What-ifs', prototypes of this beast thrown at an Olympic beach-head break-out, meeting early US T95 / T28 GMCs...

( Assuming weather misty enough to prevent interception by air-strikes. And, did whispers of this beast spawn the mega-GMC ??)

Cue grim 'Heavy Metal' knock-knock jokes...
 
This is not for China,This is for Russia

An attempt to laugh Red Army tankers into unconsciousness?
In 1939,Japanese were beaten badly by Russia in Mongolia
So,they think they need bigger tanks···
