Remember that it has been 20 years since they bought Dodonpa and 15 since Eejanaika (well, opened. Planning and development lead time accounted for, it’s probably another year or two before that where at least some money started exchanging hands). Things will have increased in price since then with inflation, we’ve seen a global economic downturn in that time, a global pandemic more recently, and you’ve also got continually fluctuating economies that will be having an impact. A quick and dirty check on an inflation calculator suggests that Eejanaika would cost around £1.5M more today than it did in 2006 and that’s without any global factors like currency exchange.
Eejanaika was also subbed out to a Japanese manufacturer, which will no doubt have saved a fortune on manufacturing and shipping costs. If this is being manufactured in Munich, as I believe most of Maurer’s rides are, it won’t be cheap shipping and importing it to Japan, I would think.
They may well be overpaying for what this ride is, but it’s not as simply as drawing a direct comparison between a ride build so many years ago. Takabisha would probably be a much fairer comparison, in terms of time and global factors, but even that was a decade ago now. Christ I feel old.
