Does Japanese have a past future tense?


In English, there is a past future tense in sentences like "I was going to go
home." I was wondering if Japanese had something like that.

> 私は東京に行くことになった。

This sentence seems to be something like "I became something that was going to
go to Tokyo." However, is it possible to indicate "was going to go to" without
the なった? For example, can 私は東京に行く mean "I was going to go to Tokyo"? At first,
I thought no, but then I thought of Japanese literature that uses the
historical present, which confused me. As an example, I tried writing how I
thought Japanese literature would be written.

> Alice had a headache. She wasn't going to go to Tokyo. I brought medicine.
>
> アリスは頭が痛かった。彼女は東京に行かない。私は薬を持ってきた。

Wouldn't 彼女は東京に行かない be "she wasn't going to go to Tokyo"? In addition, if I
wrote, "she wasn't going to go to Tokyo, so I brought medicine" and
彼女は東京に行かないから私は薬を持ってきた it still seems to work.



[code]

            (行くつもりだった and 行く予定だった are both good.)
    
[/code]

One way to say "I was going to go to Tokyo." is:

東京に行くことになっていた。

Both versions above work for 1. (still going), and 2. (no longer going) cases,
i think.

*** One diff. is that "I was going to go to Tokyo." can be used to mean. [I
just got the notice; I was going to go to Tokyo after all.] But the Jp ver.
can't be used that way. Maybe, but not in the same way.

> いやあ、ちょうど今、お届けにあがろうと思っていたところですよ。

Hello, I was going to bring it to you just now.  
Hello, I was going to go bring it to you just now.  
Hello, I was going to come by to bring it over to you just now.  
.......... I was just now thinking I should ....  
.......... I was just now thinking I would ....

> A had a headache. She wasn't going to go to Tokyo.

*** This is the aforementioned [ (((Reason))) ; A wasn't going to go to Tokyo
(after all).] pattern

（西村京太郎ふうに）

Ａは頭痛を感じた。東京には行けなくなった。

頭がズキズキしてきた。東京には行けない。

後頭部に激しい痛み。東京行きは、なくなった。

relevant in the Tense chapter.

... ことになっている。 can also be used for rules or conventions.

彼はここに来ることになっている。 plan, schedule, (past decision)

With that said, i'd say : that the correspondence has been well-established
between [ ... was going to ...] and ことになっていた。
