Unfortunately not everything is documented so there aren’t really any experts with regards to Japanese Minis, except in Japan. This forum doesn’t have much of a Japanese following.
My take is that you’ve bought MNE101351 from the UK which is expecting an immobiliser and will require it to be matched to one before it works. I think a MNE101350 from the UK would have the same issue. What you need to try and do is source MNE101350 from Japan or get your MNE101351 altered to remove the need for the immobiliser like xrocketengineer did.

Honestly the best advice I can give you is that your choices are a) send your original ECU off to get repaired, b) send your new ECU off to have the immobiliser need removed, c) keep looking for a direct working replacement ECU.
None are instant or cheap options but it is the single most important part of the SPi system so that’s not a massive shock.

I just found out this info on this website - https://memsfcr.co.uk/ecu-versions/
So 1 stands for coded, My original ecu 350 - ends with 0. So its uncoded.
What exactly it means when it says "Coded" ? Just the immobilizer?

Reading the details in the link, the page says 4th digit represents uncoded/coded, i.e. MNE101070=uncoded & MNE101170=coded.
From what I can gather the last digit of the later part numbers is the revision. So MNE101350 & MNE101351 are the same part as rev.0 and rev.1 respectively. I do not know whether parts of different revisions are interchangeable - form, fit and function? Perhaps someone on the forum has a deeper understanding of the Rover part number schemes.
Do you have access to a Rover diagnostic/programming device? The immobiliser coding disable is likely to be a software switch.
