The UK uses first-past-the-post, which would usually push the political landscape to a two party system. For various reasons, this didn't quite happen. But still, FPTP is very likely to produce majorities in parliament. For example, in the last election the tories gained a huge majority in parliament while only getting about 41% of the votes.

Japan has a mixed system, including some amount of proportional representation. But like India, they have one particular party who for historical reasons encompasses a significant share of the political landscape, and thus makes single-party majorities normal.

Israel uses a fully proportional system, and for that it is perfectly normal to not have single-party majorities. Germany (Federal Republic of), which essentially has a proportional system, too, and roughly the same age as Israel, also never had a single-party majority in parliament.

So to summarize, there is no particular reason to look into specifics of Israeli politics, their political system alone explains the absence of single-party majorities.
