If you are on the Sanriku Coast, Sanriku Railway does have a station in the east edge of Iwaizumi Town. Omoto Station is 40 min away from Miyako (¥750 single). The town council operates shuttle bus service from Omoto into town via Ryusendo Cave (¥600 single) usually connect train arrival times.

By bus
JR Tohoku Bus Co. operates a direct bus service (4 times daily) from Morioka Station to Ryusendo Cave via Iwaizumi Town Center. The journey takes 2 hr 10 min. Japan Rail Pass is accepted on this bus service.

Morioka Station - Ryusendo (via Iwaizumi), daily, ¥2590

The bus leaves from Morioka Eastside Bus Terminal, Bus Stop No.1. No toilet on the bus, but there's a break at the Mitakai SA along the way. All buses go via Iwaizumi Sanbonmatsu. (8 min before Ryusendo arrival).

By car
Another option is to hire a rental car at Morioka station. Driving in this region is less stressful than in cities like Tokyo. National Road 455 is the shortest route from Morioka, passing through picturesque Gando-ko and Sotoyama lakes. Since the new tunnel through Hayasaka Plateau was completed, the journey time has been cut -- Morioka to Iwaizumi takes around 90 minutes. In the winter, driving times are often longer and conditions are often less safe.

Get around
There are limited commuter bus links mainly serving for locals connecting between settlements, the town hall and medical center. There are a couple of useful services for visitors. One is the line mentioned above, linking between Omoto Station and Iwaizumi Town center, and the other one is to Ryusendo and Sugawatari Caves. Ryusendo can be within walking distance (although 30 mins from town center). All buses start/end at Iwaizumi Station, passing through Sanbonmatsu (8 min away) along the way.
