Line capacity is not compared value by value: Japan rates PE line in gō (号) × metres, while the US table uses lb test × yards for a named braid, and the two cannot be converted exactly.
What only the Japanese listing gives you
- Product code and JAN: 043986 (HG RIGHT) / 043993 (HG LEFT) / 4969363043986 (HG RIGHT) / 4969363043993 (HG LEFT). Use these to match a Japanese retailer's listing and to order parts.
- Spool: 29 mm dia. / 19 mm width.
Officially listed compatibility applies to the Japanese reel as listed in Japan. We have not found a statement from Shimano that the US version takes the same parts, so we do not say it does.
