Sunrise & Sunset Times in Sendai

Public observing runs every Saturday from 19:30 to 21:30. A fee applies (200 yen for ages 16 and over, 100 yen for school children) and no reservation is taken; entry may be limited when it is crowded. In bad weather the session becomes an indoor talk. You can enter only during this session. The pin is the destination marked on the observatory's official access map.

Sky: suburban (satellite night-light estimate)

The VIIRS nighttime-light estimate puts this area darker than central Sendai, but it is still a suburban sky. Observing centres on the observatory's telescopes.

Facilities: parking, public transit

Open horizon: overhead. The observatory's telescopes focus on the targets shown that night. Which directions are open has not been confirmed, so only overhead is listed.

Moon, planets, telescope observing

Go only during the Saturday public session. Roads carry snow and ice in winter. Miyagi Prefecture has issued bear advisories, so check them before you go. Follow the observatory's notices for which parts of the car park can be used at night.

The Ministry of Land, Infrastructure, Transport and Tourism requires registered roadside stations to offer free parking and toilets usable 24 hours, and Shichikashuku is on the September 2026 registration list. The operator's site says the station is on National Route 113, in a corner of the Shichikashuku Dam nature recreation park, with an EV charging station in the car park. The shops and restaurant keep their own hours.

Sky: rural (satellite night-light estimate)

The VIIRS nighttime-light estimate puts this area much darker than central Sendai. Lighting at the station and along the highway has not been confirmed on site.

Facilities: parking, toilets

Open horizon: overhead. The dam lake lies in front of the station, but which directions are actually open from the car park has not been confirmed, so only overhead is listed.

• Michi-no-Eki (roadside station): parking and toilets are open 24 hours, for a short rest and a look up only — no car camping or overnight stays. Keep quiet and do not idle your engine. Lighting at the station and on the highway is unconfirmed and may be brighter than you expect.

The station is on the shore of a dam lake, so do not walk into the dark areas along the water at night. Miyagi Prefecture has issued bear advisories, so check them before you go. Snow and ice are common in winter; check road conditions before leaving.
