Are there any good Japanese holdco’s in the vein of BRK, EXOR, INVE, etc?

Looking for a good Japanese holdco with a solid track record of outperformance. Portfolio being a mix of public and private equities.

Creating a basket in my long term oriented account with similar companies such as BRK, MKL, FFH, EXOR, INVE, etc and wanted some exposure to Japan.

Holding companies with a long track record of success and fairly valued gives bonus points.
