Short sentences plateau fast. Real Japanese strings clauses together with subordinate connectors — the equivalents of "because," "although," "while," "so that." The Te-form guide covered plain sequencing and the Conditionals guide covered "if/when"; this guide is the rest of the logical glue. The pattern is always the same: the subordinate clause comes first, in plain form, and the main clause lands at the end.
から and ので — "because"
Both give a reason. から presents it as your assertion — subjective, and a bit blunt; it can precede a command or request. ので is softer and more objective, the polite choice for explanations, excuses, and requests. With a noun or na-adjective: 〜だから / 〜なので.

| 高いから買わない | takai kara kawanai | it's expensive, so I won't buy it |
| 時間がないので、行けません | jikan ga nai node, ikemasen | I can't go, as I have no time |
けど・が and のに — contrast
けど (casual) / が (formal) is a mild "but / though" — and often just a soft preface, not real opposition (すみませんが…). のに means "even though," but it carries an extra charge of unexpectedness or dissatisfaction — and unlike けど it cannot be followed by a command, request, or intention.

| 安いけど、買わない | yasui kedo, kawanai | it's cheap, but I won't buy it |
| 勉強したのに、不合格だった | benkyō shita noni, fugōkaku datta | even though I studied, I failed |
〜し — stacking reasons
〜し lists qualities or reasons: "and what's more…". It often implies the list isn't exhaustive ("for one thing X, and also Y, and other reasons too"). Plain form + し.

| 安いし、おいしいし、ここにしよう | yasui shi, oishii shi, koko ni shiyō | it's cheap, it's tasty — let's go here |
〜たり〜たり — representative actions
A non-exhaustive list of actions: "do things like A and B (among others)." Built on the same sound change as the past tense (た → たり), and the list is closed with する, which carries the tense.

| 週末は本を読んだり、散歩したりする | shūmatsu wa hon o yondari, sanpo shitari suru | on weekends I do things like read and take walks |
〜ながら — "while"
Two actions at once, same subject: ます -stem + ながら. The ながら clause is the background activity; the main clause is the focus.

| 音楽を聞きながら勉強する | ongaku o kikinagara benkyō suru | study while listening to music |
ために and ように — purpose
Both mean "in order to," but they split by control. ために is for a goal you volitionally pursue (dictionary verb + ために, or 名詞 + のために). ように is for aiming at a state you don't directly control — it pairs with potential or non-volitional verbs, negatives (〜ないように, "so as not to"), and different subjects.

| 話せるように、毎日練習する | hanaseru yō ni, mainichi renshū suru | practice daily so I can speak |
〜とき — "when"
とき is just the noun 時 ("time") being modified by a clause — so the Noun-Modifying Clauses rules apply. The tense inside is relative: 食べるとき = "when (about to / before) eating," 食べたとき = "when (having) eaten." This trips up nearly everyone.
