No Export for You: The arcade version, especially due to its extensive use of Japanese licenses.
Somewhat subverted. The arcade version has been widely parallel-imported into several Asian countries outside of Japan. Even then the online and e-Amusement functions work (read: no IP geolocation restrictions). These parallel imported machines are even capable of downloading new music from Konami's servers without issues. The only concern the player has is getting an e-Amusement card (which the arcades with the machine also imports and sells) and understanding the text onscreen and dialogs (which is inevitably Japanese, but easily worked out with the accompanying illustrations).
