One Day in the First Capital
Ishibutai's megaliths, the Takamatsuzuka murals, Asuka-dera's ancient Buddha and the Inabuchi terraces - the flat, signposted bike loop that links them, timed for a day-tripper.
The valley is a natural loop, and the loop is a natural day. Rent wheels at the station (or arrive to a guide holding them) and take it clockwise.
Morning - the megaliths
Ishibutai Kofun first, while the light rakes and the groups haven’t landed: a burial mound stripped of its earth, leaving a chamber of thirty-ton granite blocks you walk straight into - attributed by tradition to the Soga clan’s great patriarch. It is the valley’s signature image and the morning’s easiest ride from the station.
Midday - the painted tombs and the temple
North to Takamatsuzuka, whose replica hall shows the painted courtiers and star charts that rewrote Japanese art history when the tomb was opened in the 1970s; its sibling Kitora adds the oldest star atlas of its kind. Then Asuka-dera, founded in the 590s as Buddhism’s first full-scale temple in Japan, where the bronze Great Buddha - scarred, repaired, and older than every giant that followed - still faces visitors at close range. Lunch in the lanes nearby; the valley does modest, good noodle shops rather than restaurant rows.
Afternoon - the terraces and the stones
Climb gently to the Inabuchi rice terraces - working agriculture, best in golden hour or September’s red spider lilies - via the valley’s scatter of mystery stones: carved granite oddities (the turtle, the two-faced stone) that archaeology still shrugs at, charmingly. Roll back to the station by five; rural Japan closes early and the loop should too.
The deeper reference on each site - the excavation history, the Soga politics, the full monument list - lives at asukajapan.com, which covers the valley beyond what one day needs. For the day itself: bikes, morning discipline, and the loop above. The from-Kyoto and from-Osaka pages get you to the station on time.

Ride It with the Telling
The guided cycling loop meets you at Asuka Station with the bikes and the stories - $81, free cancellation to 24 hours.
