What’s a reasonably good Senior IT salary at this point?

Hello, I’ve gotten to the stage in hiring process where it’s finally time to talk salary negotiations and I am a bit stuck, as this company is large but privately listed. It’s an ISV with generally only senior (median 15 year exp) engineers split between Europe and Japan. Note that it’s a European firm with a major presence in Japan. I'm obviously being offered in the Japanese dept.

I’m a Senior/Lead DevSecOps & SRE Specialist also with an extremely strong software engineering background. Mid 30s, have 3 master degrees and over 16 years of professional experience. Numerous cloud and security certs and generally fill Senior to Lead positions, but I have also filled CTO and some manager positions previously.

The company asked me my expectations. I would like to ask them to consider a range of ¥14-¥16M. They would require me to move to Tokyo, and I am the sole income earner, so I feel I am also incentivised to ask on the higher end.

I'm basing this on recent discussions eg. with other companies like Toyota/Woven etc. the ranges I was quoted were between 13-16M. Though I doubt anyone ever got 16M. This company is smaller though and privately listed but they are a major ISV.

I’m also a bit worried about salary stagnation and the volatility of the yen at the moment so I am trying to moderate that between asking a tone-deaf amount. How do I approach this?Can I directly turn the question back on them and ask them for a range?

Thank you so much for any advice.
