Tonami-shi

In the 2020 Population Census the population is 48,154. To read this city’s population, the merger must be taken into account. In 2004 the old Tonami City made a new merger with a neighboring town to become the present Tonami-shi. The population of the old Tonami City before the merger was 40,744 in 2000, and 49,429 in 2005 after the merger. From there, through 49,410 in 2010 and 49,000 in 2015 to 48,154 in 2020, it has moved nearly flat since the merger. The step in population between 2000 and 2005 in this article mirrors the widening of the municipal area through this merger.

Looking inside the figures, the figure of a farmland city that keeps comparative youth appears. The share aged 65 and over rose from 21.0% in 2000 to 30.3% in 2020, but while many regional cities draw near four in ten, it stays at about three in ten. Households with children make up a high 24.9% (2020), and the Childcare Waitlist was zero in both 2024 and 2025. The Fiscal Capacity Index was 0.57 in fiscal 2023 — a level whose own tax revenue covers nearly six-tenths of expenditure, which is in the middle range for a small or mid-sized city. The numbers show the city where houses with homestead woodland scatter, keeping comparative youth while holding its population nearly steady within the post-merger municipal area. Why it takes this shape cannot be read without going back over the history of the scattered settlements and bulb cultivation.

What makes Tonami up is the form of a dispersed village born on the plain of an alluvial fan, the bulb cultivation raised on that plain, and the merger that widened the municipal area. The central layer is the plain. This city lies on a landform that opens like a fan, formed where a great river flows out from the mountains onto the plain. On this land, where water sinks easily into the ground and where paddies could be cultivated to the plain’s every corner by drawing water throughout, the houses did not cluster into a single settlement; instead each farmhouse chose to dwell in the middle of its own field. Around the houses, homestead woodland was planted to protect the living from wind and snow, and the scene of a dispersed village was born — farmhouses ringed by homestead woodland scattering one by one among the rice paddies. A rich plain that could be cultivated widely into paddy raised this distinctive form of village.

And in the modern era, this plain held, along with rice farming, another product. Because the well-draining soil of the alluvial fan suited the cultivation of bulbs, the farming of flower bulbs flourished on this land, and its shipping volume in time became the top in the nation. When spring comes, the flowers of the bulbs planted in the fields dye the whole in many colors, and an event to see that scene came to be held. The path by which it became a city also mirrors this city. In the mid-Showa era, this land became a city centered on the town at the center of the plain, and in 2004 it made a new merger with a neighboring town, taking into its municipal area even the mountains upstream of the alluvial fan. The scattered settlements of the alluvial fan and being Japan’s top in bulb cultivation — the history carried by the plain of an alluvial fan that a great river formed lies at the foundation of today’s Tonami.

What characterizes Tonami-shi is that, while holding the history of scattered settlements and bulb cultivation, it holds the post-merger municipal area’s population nearly steady and keeps comparative youth for a farmland city. From 49,429 in the post-merger 2005 to 48,154 in 2020, it has barely changed over fifteen years. That a farmland city opening onto a rich plain has not greatly broken its population can be read as coming from its also being blessed with convenient commuting to nearby cities, where a living of holding a place of work alongside farming has held up. That the share aged 65 and over stays at about three in ten at 30.3% in 2020, and that the household-with-children share is high at 24.9%, are expressions of young households having kept on living here.

On the other hand, the Childcare Waitlist was zero in both 2024 and 2025. A Fiscal Capacity Index of 0.57 is a level whose own tax revenue covers nearly six-tenths of expenditure, in the middle range for a small or mid-sized city. As a farmland city, farming and the income of those who live here and work nearby can be read as supporting the tax source at the middle range. Population is nearly flat after the merger, aging stays at about three in ten, the household-with-children share is high, fiscal stamina is in the middle range — that the color of contraction is faint for a farmland city is the figure of Tonami, opening onto an alluvial fan, in its numbers. The single word “farmland” cannot read this youth held up by convenient commuting.

Tonami holds several functions of its own. One is the history of the form of a dispersed village — farmhouses ringed by homestead woodland scattering one by one among the rice paddies — holding the distinctive scene born on a land cultivated into paddy to the alluvial fan’s every corner. Another is the bulb cultivation raised on the well-draining soil of the alluvial fan, keeping the character of its shipping volume having become the top in the nation. And the landform of a plain that opens like a fan, formed by a great river, called forth the scattered settlements and called forth the bulb cultivation.

Tonami is a city of scattered settlements and bulb cultivation, where houses with homestead woodland scatter across the plain. From a dispersed village where each farmhouse dwells in the middle of its field to a district of bulb flowers raised on the soil of the alluvial fan — the geography of “opening onto the plain of an alluvial fan that a great river formed” called forth the scattered settlements and called forth the bulb cultivation. In the western part of Toyama Prefecture, upon the plain of an alluvial fan, the scene of houses with homestead woodland scattering one by one across the fields is the face of the city of Tonami.
