you do realize that the ājapaneseā tiger 1 never made it to japan and was quickly returned back to german hands? now japan did get some panzer 3s and 4s for testing as well as 109s so those can be useful at lower brs.
Unless you want more Fantasy Tanks for Japan , then Tiger 1 is the best bet yeah there is Chi-ri but should I say this its not worthy of BR 5 , Then again if you want more fantasy stuff there were tons of Ho-ri sketches that can be used also there is O-I but with 11 man I would just use it as mobile troops other than that there is Heavy tank NO.4 which it seems that the turret was built (debatable )
It was meant to be mounted on Chi-ri chassis but again Chi-ri production itself wasnāt doing well(It has I think 14 cm cannon)
So, having gotten my hands on David Listerās book, I can now effectively catalogue all of the (Known) Japanese Heavies that were built. Using his book iāve counted 12 seperate designs:
Type 91
Type 94 (Ro-Go)
Experimental II
Type 96 (AI-96)
Mitsu-97(Type 97)
Ishi 108
Mitsu 104
Showa 10
Unknown 54-ton design (10CM gun)
O-I
Type 4
āMedeltung Stridsvagnā (unknown heavy from swedish reports)
These are all the heavy(Known) tanks for Japan but most are unknown no pictures just a brief description
Like I said even though they are known to have been built to some degree some of them even donāt have pictures Japan was secretive country they even drowned I think the 2 Chi-to tanks that were build so Americans couldnāt get them and also most likely half of these tanks were cannibalised for resource like O-I since they needed materials and Japan didnāt have the capabilities to sustain heavy tanks as Germany and Soviets
