Hello, Some source point out that a 100 tonne OI was at least considered or even build but some of them dont talk about this project,so true or false?:
http://www.tanks-encyclopedia.com/ww2/jap/O-I.php (this one doesn't seem to talk about him

Before, it was believed that there were two heavy tanks, 100t and 120t heavy tanks. But, Mitsubish document which was newly found revealed that they are the same tank. So, there was only one heavy tank O-I.

No, it mistook one tank for two different tanks. It is definitely stated in Japanese Wiki.

従来資料では100t、120tの2種の車輌が個々に開発されたとする説があったが、試作を命じられた三菱重工業の当時の資料が発見されたことにより否定された。実際に試作されたのは予定重量150tの車輌のみである[4][5]。
(Google translation)
According to previous data, it was described that two types of vehicles, 100t and 120t, were developed individually, but this was denied because the data at the time of Mitsubishi Heavy Industries, which was ordered to be prototyped, was discovered. It is only a vehicle with a planned weight of 150 tons that was actually prototyped

https://ja.wikipedia.org/wiki/%E3%82%AA ... 4%E8%BB%8A

Above description in Japanese WIki is based on the book of Japanese heavy tank that I introduced you before.

Google translate is awkward but useable to translate either to English to French, I just ran a portion of the text through in both languages.

The book of Japanese heavy tank guesses that it mistook the weight of O-I excluding the turret for the total weight. It weighs approx. 100 ton.

I want to know something: when the prototype was build(and seem to have been tested) did he have turret or not?

It had no turret and it weighed 100 ton. So, it would be wrongly known as 100 ton tank.

The test ended in the miserable result. Read "Testing" in the below link.
