Would I be making a stupid decision to leave my comfortable career to move to Japan?

I’m in my lates 20s (soon 30s) in the UK, a software engineer with 4 years experience.
I own a house in London where I rent out a room that pays for the mortgage.

For the last few years I’ve been lucky to have a well paying job at a great company and I’m on £80k a year atm.

I’m well travelled and have been all over the world and love learning languages, and ew experiences. I’ve been wanting to get some new life experiences and live abroad for a few years and have been applying for jobs in a few countries (US, Canada, Germany, S.Korea, Singapore, Japan.

I’ve been lucky to receive an offer recently in Tokyo with a Japan based fintech company, for ¥8m/year, of course, that’s almost 40% lower than my current salary due to weak Yen, although after tax the difference is closer to 25% (still significant!).

I’d love the opportunity to live somewhere new for a few years (and maybe longer if I end up loving the life there!), but I can’t keep the thought in the back of my head of such a big drop in salary, even though I know that the salary is much higher than the average salary in Japan and can lead to a pretty good life.

I’m very much an average engineer, so FAANG companies are out of the realm of possiblity for me at the moment, or for the foreseeable future.

I’m stuck weighing the thought of saving up a decent amount of money at home vs getting new life experiences.

Any advice?
