The very best or most outstanding within a particular group or category. Always used with a preceding scope (e.g., 日本随一 — the best in Japan).
Compound of 随 (follow/accompany) + 一 (number one). Always preceded by a scope that specifies the group being compared.
Common patterns
- 日本随一の～ (Japan's foremost ~)
- 世界随一の～ (the world's foremost ~)
- 社内随一の～ (the company's best ~)

Usage
A formal expression of superlative praise. More literary and elevated than 一番. Cannot be used without a preceding group or category — you cannot say just 随一 alone.
