Technically they’re different shares. The US one is called an American Depository Receipt (ADR). It’s a cheaper way for non-US companies to get access to US investors without having to go through all the steps and expense of listing on one of the US indices. There would be a different number of issued shares for each. For example 1 share of the Japanese listing might equal 4 ADRs etc. That’s why there’s such a difference.
Slightly more advanced topic: Some people will try to trade an arbitrage between the two listings after adjusting for currency moves.
