Jupiter rules houses 5 and 8 for Leo rising — mildly benefic. The rules behind that verdict, dasha themes and how it compares with the other planets.
✦ Generate My Free Birth ChartFor Leo rising, Jupiter comes out net-supportive. It rules Sagittarius (the 5th house) and Pisces (the 8th house), so its Mahadasha (16 years) concentrates on children, creativity and intellect and transformation, longevity and sudden events.
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 5th house (Trikona); Sagittarius is Jupiter's moolatrikona sign, so it counts 1.5× | +3.0 |
| Pisces is the 8th house (Dusthana) | -2.5 |
| The lagna lord Sun regards Jupiter as a natural friend | +0.5 |
| Net score → Mildly Benefic | +1.00 |

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 Leo rising it activates the 5th house (children, creativity and intellect) and the 8th house (transformation, longevity and sudden events). A well-supported period therefore tends to lift those areas; 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.
Leo is a fixed sign, so its Badhaka (obstruction) house is the 9th, whose sign is Aries and whose lord is Mars. Jupiter is not the Badhaka lord. The Maraka lords for Leo rising are Mercury (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 mildly benefic 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.
