Questions & Answers about junro wa kochira desu.

How do you read 順路?

It is read じゅんろ (junro).

• 順 = order / sequence
• 路 = road / route / path

Together, 順路 means something like route, course, or the proper way to go, especially on signs in places like museums, exhibitions, temples, or events.

Why is は pronounced wa here instead of ha?

Because は is being used as the topic particle, and when は is a particle, it is pronounced wa, not ha.

So in:

• 順路は

the pronunciation is じゅんろ は → junro wa

This is one of the first spelling/pronunciation exceptions learners meet in Japanese. The written form stays は, but the spoken form is wa when it marks the topic.
