Semboku

仙北市せんぼくしSenboku-shi

Samurai houses, Japan's deepest lake and hot springs in the beech forest

Semboku is a city in eastern Akita that brings together the samurai town of Kakunodate, Lake Tazawa – at 423.4 metres the deepest lake in Japan – and the hot springs of Nyuto and Tamagawa in the Ou Mountains. It was formed in 2005 by the merger of Kakunodate, Tazawako and Nishiki.

Overview

Semboku – officially romanised with an 'm', Senboku in standard Hepburn – covers a large area of eastern Akita between the Ou Mountains on the Iwate border and the Semboku plain. Much of it is forest and mountain, part of Towada-Hachimantai National Park, and the city is one of the snowiest in the prefecture.

Its best-known part is Kakunodate, a castle town laid out in 1620 whose samurai quarter, with black board fences, broad streets and hundreds of weeping cherry trees, is one of the most complete in northern Japan. North-east of it lies Lake Tazawa, a deep blue caldera lake ringed by forest. Higher up, the beech woods of Mount Nyuto and the volcanic highlands of Hachimantai shelter some of Tohoku's most traditional hot-spring inns.

History

Kakunodate began as a fortified settlement on Mount Furushiro. After the Satake were moved to Akita in 1602, the domain assigned Kakunodate to Ashina Yoshikatsu, who in 1620 relocated the town to the flat land south of the hill and divided it by a firebreak into a samurai quarter (Uchimachi) and a merchants' quarter (Tomachi) – a plan that survives. From 1656 the Satake-Kita branch family governed the town until 1871.

In the eighteenth century Kakunodate samurai became known for cherry-bark craftwork and for painting: Odano Naotake, a local samurai, led the Akita school of Western-style painting. The samurai district was designated an Important Preservation District for Groups of Traditional Buildings in 1976. Lake Tazawa's ecology was transformed from 1940, when acidic water from the Tamagawa river was diverted into it for hydropower and irrigation; the lake's endemic black kokanee (kunimasu) disappeared, and was only rediscovered in 2010 in Lake Saiko near Mount Fuji, where eggs had once been sent.

Culture

Kakunodate cultivates its identity as a samurai town, sometimes called the 'little Kyoto of Michinoku'. Cherry-bark craft, the memory of the Akita ranga painters and the yearly float festival give the town a cultural life beyond sightseeing. In the mountains, the hot-spring inns preserve an older tradition of toji, long cure stays, while Lake Tazawa is surrounded by legends of Tatsuko and the dragon Hachiro.

Frequently asked questions

When do the cherries bloom in Kakunodate?

Usually from late April to early May; the weeping cherries in the samurai district tend to open a little before the trees along the Hinokinai River.

Why is the city called Semboku and not Senboku?

The city uses the romanisation Semboku, following the older Hepburn convention of writing 'm' before 'b'; in modified Hepburn the name is Senboku.

How deep is Lake Tazawa?

Lake Tazawa is 423.4 metres deep, the deepest lake in Japan. Because it rarely freezes, it stays open even in the coldest winters.

Can Nyuto Onsen be visited as a day trip?

Yes. Buses run from Tazawako Station, and most of the inns accept day bathers, though an overnight stay is the traditional way to experience them.
