Jupiter rules houses 6 and 9 for Cancer rising — neutral / mixed. The rules behind that verdict, dasha themes and how it compares with the other planets.
✦ Generate My Free Birth ChartFor Cancer rising, Jupiter comes out balanced, with real pros and cons. It rules Sagittarius (the 6th house) and Pisces (the 9th house), so its Mahadasha (16 years) concentrates on debts, disease and rivals and fortune, dharma and the father.
Each rule below is applied in turn; the verdict is the sum. Positive numbers support the planet, negative ones weigh against it.
| Rule applied | Weight |
|---|---|
| Sagittarius is the 6th house (Dusthana / trishadaya); Sagittarius is Jupiter's moolatrikona sign, so it counts 1.5× | -3.0 |
| Pisces is the 9th house (Trikona (strongest)) | +2.5 |
| The lagna lord Moon is neutral toward Jupiter | 0.0 |
| Net score → Neutral / Mixed | -0.50 |
Sagittarius — house 6 (Dusthana / trishadaya). The 6th house governs debts, disease and rivals. Whatever Jupiter promises or withholds in a chart tends to be delivered through these matters. It is also the planet's moolatrikona sign.
Pisces — house 9 (Trikona (strongest)). The 9th house governs fortune, dharma and the father. Whatever Jupiter promises or withholds in a chart tends to be delivered through these matters.

Rahu and Ketu own no signs, so they have no lordship to classify; they act through the sign lord of the sign they occupy and the planets they join (see Rahu & Ketu in KP).
In the Vimshottari system Jupiter's Mahadasha lasts 16 years out of the 120-year cycle. For Cancer rising it activates the 6th house (debts, disease and rivals) and the 9th house (fortune, dharma and the father). Expect those areas to be mixed — progress alongside friction; the sub-lords of the period and the transits at the time decide which way it actually goes. See Jupiter Mahadasha for the period itself.
Cancer is a movable sign, so its Badhaka (obstruction) house is the 11th, whose sign is Taurus and whose lord is Venus. Jupiter is not the Badhaka lord. The Maraka lords for Cancer rising are Sun (2nd) and Saturn (7th); Jupiter is not one of them.
In KP astrology, ruling a house by sign is only the weakest of the four levels a planet can signify through (the others are occupying it and the star-lord links). A neutral / mixed reading by lordship is useful context, but the sub-lord chain in the actual chart is what decides outcomes. See Significators in KP and Sub-Lord Theory.
