It is relative value, not free money. A Japanese box holds 30 packs to English's 36, pulls from a different card pool, and carries no English text. Importing adds shipping and customs.
Japanese sets also release roughly half a year ahead of their English counterpart, so the Japanese side often moves first. A premium that is narrowing or widening over time says more than the level alone.
