• 五輪ごりん — the Olympic Games (five rings)

五感ごかん means the five senses — sight, hearing, touch, taste, and smell — a concept found in both science and everyday culture.

五輪ごりん represents the Olympic Games. The five interlocked rings symbolize unity across five continents.

The most common reading of 五 is ご, as in 五人ごにん (five people). You might also hear いつつ — but it’s used less often and mostly in traditional counting.
