Tsumago's TIC is in the centre of town, by the antique phone booth. Some English is spoken and there's English-language literature. Ask here for any directions.
Across from the train station, the friendly staff here have some English maps, but appreciate some Japanese-language ability.
Located somewhat inconveniently halfway up the hill, to the right. A baggage forwarding service to Tsumago is available.
Inside Narai Station, this tourist office has some English-language leaflets and a map. Little English is spoken.
