Limited Express Hokuto trains stop here.27 The town office gives about 60 minutes from Hakodate and about 180 minutes from Sapporo.49 Other stations in the town are Akaigawa, Komagatake and Ishikura on the main line, and Oshima-Numajiri, Oshima-Sawara, Kakema, Oshirauchi and Higashi-Mori on the Sawara Branch. The Sawara Branch leaves the main line at Ōnuma and follows the coast back to Mori.129
- Road: National Route 5 runs from Hakodate through the town center, and Route 278 follows the Sawara coast.1 On the Doō Expressway (E5), Mori IC (No. 7) lies between Ōnuma-Kōen IC and Otoshibe IC.31 By car, the town office gives about 60 minutes from Hakodate and about 240 minutes from Sapporo.49
- Bus: local routes are run by Hakodate Bus (函館バス), which links Mori with Hakodate, Nanae, Yakumo and Oshamambe. The Kōsoku Hakodate (高速はこだて号) express bus runs between Mori and Sapporo, and the town runs its own community bus, Morikkuru (もりっくる).1 The express bus stops at "Morimachi" (森町), by Michi-no-Eki YOU・遊・もり.

- Plan ahead for Washinoki: the stone circle is open only on announced viewing days, so check the town website.43 For the rest of the year, the excavation office exhibits are the best substitute.44
- Tourist information: the town publishes a digital tourist brochure in Japanese, English, Korean and Chinese. It asks visitors to contact each provider in advance before booking any experience listed in it.50
- Summer afternoons in Sawara: Tsudōru Plaza Sawara closes at 16:00 from July to October.38
- Winter: snow has reached 89 cm deep in recent winters, and temperatures fall below −15 °C.4 Use winter tires and allow extra time on Routes 5 and 278.
- Wildlife and volcano: brown bears are sighted in the Torisaki gorge every year. The town asks visitors to carry something that makes noise, wear conspicuous clothing and take all rubbish home.45 Komagatake is an active volcano, so obey any entry restrictions, and come down at once if you hear a siren.1323

Name origin
- Oniushi: the town's own history page says the area was long called Oniushi (オニウシ) in Ainu, "a place with many trees".6 Japanese Wikipedia says the name "Mori" (森, "forest") is a free translation (意訳) of that name.1 The page on the Kayabe chestnut grove adds that Ainu residents gave the name when the area was covered by primeval forest.22
- River-name theory (unverified): the place-name scholar Yamada Hidezō traced the name to o-ni-us-pet, "river where trees grow thickly at its mouth". This was his name for the Torisaki River (鳥崎川), west of the town center. On this reading the name was shortened to Oniushi and then translated as 森. The source is the Hokkaido Government's Ainu place-name list, which could not be reached online on the access date.
- Sawara (砂原): the former town's name is said to come from Ainu Sarakiushi (サラキウシ), "place where tall reeds (鬼茅) grow".7
- Reading: Mori is the only town in Hokkaido read -machi. Its sister town, Mori (森町) in Shizuoka Prefecture, is also the only machi in its own prefecture.1
History
- Jomon period (about 4,000 years ago): the Washinoki stone circle and its pit-grave area were built. Thick ash from Komagatake's Edo-period eruptions later buried the site and preserved it well.17
- 1640: Komagatake had the largest of its recorded eruptions (VEI 5; later major eruptions were VEI 4). Its flank collapsed into the bay, and the resulting tsunami killed about 700 people.23
- Early Edo period: fishermen from around Hakodate came seasonally to fish for herring. Washinoki became the main village in 1738.6
- 1757: fishermen raised the herring memorial stone (鯡供養塔). Catches were then so large that surplus fish had to be buried.24
- 1800–1858: the shogunate declared the area Japanese-settled land (和人地) and ended the trading-post (場所) system. Washinoki, Mori and Oshirauchi villages were formally established in 1858.6
- 1855–56: the shogunate ordered five domains to guard Ezo, and the Nambu domain built the Sawara outpost (砂原陣屋) with about 50 troops.25
- 1868 (old calendar, 20th day of the 10th month): Enomoto Takeaki landed at Washinoki with 8 warships and about 3,000 men, including Hijikata Toshizō and Ōtori Keisuke. This landing began the Battle of Hakodate.18
- 1872: the Kaitakushi (Hokkaido Development Commission) opened a Mori branch office.1
- 1873: the Sapporo Main Road opened. It joined a 45.2 km road from Hakodate to Mori with a sea crossing from Mori to Muroran, and piers were built at both ports.26
- 1878: Isabella Bird spent a night at an inn in Mori on her way to Biratori and described the village in Unbeaten Tracks in Japan.1
- 1902–1921: six villages merged into Mori Village in 1902. Mori became a first-class village under the town-and-village system in 1907, and a town in 1921.6 Mori Station opened in 1903.27 Sawara Village formed in 1906.7
- 1915: 1,000 Somei Yoshino cherry trees were planted in Aobagaoka Park to mark the enthronement of Emperor Taishō. Some of these trees, now more than 100 years old, still stand.28
- 1920: Kuzuhara Ihei (葛原猪平), a businessman from Ogōri in Yamaguchi Prefecture, opened Japan's first full-scale freezing plant in the Minato-machi district. It froze fish from the Mori coast. Its US-made compressor ran until 1969.19
- 1941: ikameshi was created at Mori Station.10
- 1927–1945: the private Oshima Kaigan Railway (渡島海岸鉄道) opened along the coast between Mori and Sawara in 1927–28. The state bought it in January 1945 and extended it to Gunkawa (now Ōnuma) in June 1945, which created the Sawara Branch (砂原支線) of the Hakodate Main Line.29
- 1950: population peaked. The combined census population of Mori (24,294) and Sawara (8,568) reached 32,862.2
- 1961: the Great Mori Fire burned most of the town center.6 English Wikipedia puts the loss at 554 homes.5 Japanese Wikipedia dates the fire to 23 October 1961 and gives 407 homes destroyed.1

- 2003–2006: archaeologists found the Washinoki stone circle while surveying the route of the Doō Expressway. It was designated a National Historic Site on 26 January 2006, and the expressway was built in a tunnel beneath it.3031

- 2011–2012: the Doō Expressway reached Mori IC, from Otoshibe in 2011 and from Ōnuma-Kōen in 2012.31
- 2021: the Jomon Prehistoric Sites were inscribed as a World Heritage Site. Washinoki is listed as a related property.17 Japanese Wikipedia says it was dropped as a full component because the surrounding industrial land made a buffer zone difficult to secure.32
- 2023: a 2,000 kW binary-cycle geothermal unit began operating. It uses residual hot water from the Mori plant.20
- 2025–2026: the town introduced Ikamori-kun.9 It is also offering the naming rights to a newly identified cherry variety in Aobagaoka Park as a furusato nozei gift, for a donation of ¥100 million. Nobody applied by the original 15 February deadline, so the call was extended to 31 October 2026.28

-
Setting: Mori lies on the eastern side of the Oshima Peninsula and faces Uchiura Bay. The land rises inland to forests and mountains.5 Hokkaido Komagatake is made up of two main peaks, Kengamine (剣ヶ峯, 1,131 m) and Sunaharadake (砂原岳, 1,113 m).13 The volcano is rated Activity Rank A.

-
Nigorikawa caldera (濁川カルデラ): a volcanic basin in the northwest of the town. It holds Nigorikawa Onsen and the geothermal plant.21

Other important catches were sardine (9,053 t), walleye pollock (2,989 t) and mackerel (2,946 t).12 The coast where Enomoto landed is now lined with scallop farms.18 The town is also working with Nippon Talc and Mitsui & Co.

Furusato nozei: Mori takes hometown-tax donations through many portals.

The Ministry of Internal Affairs judged its high-value seafood gifts inappropriate, and when the rules changed in June 2019 Mori was at first admitted to the scheme for only four months.1 The town also warns of scam websites that pretend to offer its gifts.36

Ainu heritage
Japanese Wikipedia notes that the Satsumon and then the Ainu cultures developed here after the Jomon period, and that there were Ainu settlements in the area from the medieval period. From the 16th century, Wajin settlers from Honshu lived alongside them.1 Today the Ainu legacy is most visible in place names: Oniushi, which gave the town its name; Sarakiushi, the source of Sawara;67 and Poroso ("big waterfall"), the Ainu name for the Kami-ōtaki falls in the Torisaki gorge.45 The town's best-known prehistoric site, Washinoki, is much older than Ainu culture: it dates from the Late Jomon period, about 4,000 years ago.17
