Kenjōgo I (謙譲語Ⅰ) humbles *your* action when it is directed at someone you should elevate — visiting a teacher, asking a client, giving something to a manager. Sonkeigo lifts *their* action; kenjō I lowers *yours* toward them. The examples below are live Business-style rewrites.
Clear “toward”: visit the professor
Input
I will visit the professor's office tomorrow.
Natural Japanese
明日、教授の研究室へ伺います。
伺う is classic kenjō I for “go / visit” aimed at an elevated person or place. The visit is toward the professor — that is the required “toward.”

Ask an elevated person
Input
I would like to ask the client about the schedule.
Natural Japanese
スケジュールにつきまして、お伺いしたく存じます。
Here 伺う means “ask / inquire,” still kenjō I: your asking is aimed at the client. The rewrite softens further with 〜したく存じます.

No elevated “toward”? Don’t force 伺う
Input
Tomorrow I will go to the station.
Natural Japanese
明日、駅へ参ります。
A station is not an elevated person. Forcing 「駅に伺います」 often sounds like empty self-lowering. The Business rewrite uses 参ります (kenjō II / teichō) — careful wording toward the listener, not “elevate the station.”

Another kenjō I pattern: send / give toward someone
Input
I will send the report to the manager.
Natural Japanese
マネージャーに報告書を送付いたします。
送付いたします humbles your act of sending toward the manager. Same wiring: your action → elevated recipient.
Rewritten with Tadashii Kotoba — Business style, recipient: client (live API).
Quick check before you use kenjō I
Ask: is my action aimed at a specific elevated person (or their place / side)? If yes → kenjō I (伺う, 申し上げる, 差し上げる, いただく…). If you only need a careful tone to the listener, with no clear “toward” → often kenjō II / teichō (参る, 申す, いたす) is the better fit.
