Japanese Plug and Play Ghetto Grammar JPPGG©#103
Verb in Plain Form (P.F.) + HAZU DESU - You ought to . . .
How to say you ought to (_some verb_), in Japanese.
Ought to – HAZU

In Japanese, to say that something is expected to happen, or that something ought to happen, use the following grammar constructions:

Verb in Plain Form (P.F) + HAZU DESU
Verb (P.F.) + HAZU GA ARU
Verb in (P.F.) GA NAI

Both past and present tense cases are present. So all you have to do is plug in some Japanese verb that sounds appropriate and listen to what kind of reactions words get with the native Japanese. You see, you have to test a lot of words out to see if some of the ones you have been learning are even still in use. For as such may occasion be that the word has changed in its colloquial setting or you may find that you don’t yet have a firm and complete understanding of some words. Use this grammar principle next time you want to test out new ways of saying things. Listen to how your words are responded to and with what kinds of words.

Verb(Base TA) + HAZU GA ARU

Examples:

1. IKU HAZU GA NAI DESU *– (He) ought to have left (went) There is no reason for him to go.

2. AYAMARU HAZU GA NAI DESU* – He shouldn’t have to apologize

3. TANOSHIKU NARU HAZU DA – It ought to start getting fun, it ought to be fun. It ought to get better from here on out.

4. ARU JA NAI? Don’t you have one?

5. ARU HAZU YO! – I should have one, or, “It ought to be there”

5a. A little KAIWA to learn by –

Tanakasan (to Miurasan):
“DENSHI DENKI ARU?” –
{Do you have a flashlight?}

Miurasan:”DOKKA MITA YO!
DOKKA NI ARU HAZU DESU.”
{I saw them somewhere!)

(They've got to be here. They ought to be here)

Lets end last with a good solid definition of HAZU – Not to be confused with the goby fish or haze because those are some fine tasting fish quite delicious when dipped from tempura batter and fried like shrimp dipped in batter ~ barioishii!

* About nai desu vs. arimasen -

Which of the two phrases nai desu or arimasen is a more polite way of saying that there isn’t such a thing or that none exists? Both are used quite interchangeably but arguably, arimasen is the better choice. Avoiding the plain form of verbs and cheating its elegance of verb formation as in the MASEN of ARU in base II versus a fake and cheap desu ending, although it is a polite form of the verb -to be- makes it a worse choice between the two. Nai is still plain form and aru has been verbalized and conjugates out into arimasen,
