In short

Honorific forms raise the other person; humble forms (謙譲語 kenjōgo) lower you, and the social gap comes out the same. So the question before every keigo verb is only ever “whose action is this?” - their action gets ご覧になる goran ni naru, mine gets 拝見する haiken suru. Most of this lesson is for recognition: you will hear it in shops, on trains and on the phone long before you need to produce it.

The rule

Japanese has two ways of showing deference, and they are not interchangeable. 尊敬語 sonkeigo elevates the subject of the action, so it can only be used for someone else. 謙譲語 kenjōgo lowers the subject, so it can only be used for yourself and your in-group (ウチ - your family, your company, whoever you are speaking for). Applying a humble verb to your listener is not merely clumsy - it insults them.

Step 1 - Ask who performs the action. Them -> honorific. Me or my side -> humble. Neither (a train, the weather, a general fact) -> plain 丁寧語, or the courteous forms in Step 4.

Step 2 - Check for a suppletive verb. The everyday verbs do not take a prefix; they are simply replaced by a different word. 見る -> 拝見する, 言う -> 申す／申し上げる, 行く／来る -> 参る／伺う, する -> いたす, 会う -> お目にかかる, 聞く／受ける -> 承る uketamawaru. There is no rule here - these are memorised.

Step 3 - For everything else, use the productive frame: お／ご + ます-stem + する（いたす）. Native (和語) verbs take お: 持つ -> 持ち -> お持ちします o-mochi shimasu (“I’ll carry it”). Sino-Japanese する-nouns take ご: 説明する -> ご説明します go-setsumei shimasu. いたす is the humble する, so ご説明いたします is one notch politer than ご説明します. A handful of Sino-Japanese words take お by convention: お電話します, お返事します. The critical restriction: this frame only works when the action reaches the listener or someone you are elevating. お持ちします is fine because I carry your bag; ×お歩きします for walking to the station on my own is nonsense, because there is no one for the humbleness to point at. If nobody is on the receiving end, just use ます.

Step 4 - Distinguish 謙譲語 I from 謙譲語 II (丁重語 teichōgo). This is the point that makes the whole system click.

• 謙譲語 I raises the person the action is directed at. It needs such a person. 伺う, 申し上げる, 拝見する, お目にかかる, 差し上げる, and the whole お／ご〜する frame belong here. 部長に申し上げます raises the department head.
• 謙譲語 II (丁重語) raises nobody; it merely presents your action courteously to the listener. 参る, 申す, いたす, おる, 存じる belong here, and they normally appear with ます.

That is why 電車が参ります Densha ga mairimasu (“the train is arriving”) is perfectly normal Japanese while ×電車が伺います is not: a train has no one to defer to, but the announcer is still being courteous to passengers. The same logic gives 雨が降っております and 弟が申しました.

Step 5 - 〜ていただく: the benefactive humble. This is 〜てもらう one level up: I receive the favour of your doing something. Because it is 謙譲語, the subject is still the receiver - me - and not the person doing the favour. Its potential, 〜ていただけます, builds the politest request ladder in the language, and adding a negative or でしょうか adds more room to decline - longer is politer, mechanically. The variant お + ます-stem + いただく (お待ちいただけますか) is the same 謙譲語 I built on the お-stem frame instead of the て-form, and it is the standard shop-and-office request.

Step 6 - 〜させていただく, carefully. Causative + いただく = “I receive permission to do X” -> a very deferential announcement of your own action: 説明させていただきます (“allow me to explain”). It properly needs two things: someone whose permission is plausibly involved, and a benefit to you. Modern business Japanese has stretched it far past that (閉店させていただきます), and native speakers themselves complain about the over-use. Use it for genuinely permission-shaped acts - taking leave, presenting, taking a photo - and prefer plain いたします elsewhere.

二重敬語 and 敬語連結 are not the same thing. The Agency for Cultural Affairs’ 敬語の指針 defines 二重敬語 as one word taking the same kind of keigo twice - お読みになる plus 〜れる gives ×お読みになられる - and judges it generally inappropriate. Two different verbs, each made keigo and joined by て, is 敬語連結 instead: 拝見させていただく is 見る -> 拝見する, made causative (拝見させる, as in Step 6), plus もらう -> いただく, and the 指針 accepts that pattern (its own example is ご案内してさしあげる) as long as each piece is used correctly and the people raised do not conflict. So 拝見させていただきます is wordy rather than wrong - but 拝見します says the same thing, and is what you should reach for. On the 二重敬語 side the 伺う family is the standing exception: the 指針 lists お伺いする, お伺いいたす and お伺い申し上げる as double keigo that custom has made correct, so お伺いいたします is safe to use.

Examples

Common mistakes

• 先生が資料をお持ちします。 (Sensei ga shiryō o o-mochi shimasu.) -> 先生が資料をお持ちになります。 (Sensei ga shiryō o o-mochi ni narimasu.) - お〜する is humble, so it lowers whoever performs the action. For the teacher’s own action you need the honorific frame お〜になる.
• お客様がそう申しました。 (O-kyaku-sama ga sō mōshimashita.) -> お客様がそうおっしゃいました。 (O-kyaku-sama ga sō osshaimashita.) - 申す humbles the speaker’s side. Pointing it at the customer drags them down instead of raising them.
• お名前は何と申しますか。 (O-namae wa nan to mōshimasu ka.) -> お名前は何とおっしゃいますか。 (O-namae wa nan to osshaimasu ka.) - the same error in the commonest place of all: 〜と申します is only ever about yourself.
• お先にお食べします。 (O-saki ni o-tabe shimasu.) -> お先にいただきます。 (O-saki ni itadakimasu.) - お〜する is 謙譲語 I, which needs a person the action is directed at. Eating has none, so the frame cannot be built at all - the 敬語の指針 lists ×お食べする beside ×ご乗車する. Use the suppletive humble いただく.
• 明日は休まさせていただきます。 (Asu wa yasumasasete itadakimasu.) -> 明日は休ませていただきます。 (Asu wa yasumasete itadakimasu.) - the notorious さ入れ言葉. 休む is a 五段 verb, so the causative is 休ませる - only 一段 and 来る／する insert さ.

Tips

• One question decides everything: whose action is it? Write the two columns of the core table on one card - their action left, my action right - and drill only the direction. Learners who know the words still fail because they grab the wrong column under pressure.
• Aim for recognition first. You will be addressed in keigo (ご覧になりますか, お待ちください) hundreds of times before you need to produce it. In the meantime plain です／ます is perfectly acceptable from a foreign speaker; a wrong humble form aimed at your listener is not. When in doubt, be simple rather than fancy.
• 伺う has a second life as “ask”. 少し伺いたいのですが Sukoshi ukagaitai no desu ga is the polite opening for “may I ask something?” - the same verb that means “visit”. Context separates them, and both are equally frequent.
• ております is the humble 〜ている, not a separate grammar point. Any 〜ています in a formal e-mail or announcement becomes 〜ております: 待っています -> お待ちしております, 知っています -> 存じております. It costs nothing to learn and instantly raises the register of everything you already say.
