足りないものは、自分の手で生み出す。木工作家である父親の影響もあるのだろうが、成瀬さんはとにかく手を動かすことで、自分の思想を具現化していく。絵を描くことも同じ範疇に属すのだろうか。星野道夫や『グレートジャーニー』で知られる関野吉晴など、自然との関わりを表現する人々の影響を受けて育ったことが、絵を描くことへ、表現することへと向かった理由のひとつだった。「絵を描いて暮らしていくためには、東京へ出なければ」。山梨の大学を卒業したばかりの成瀬さんはそう考えていた。上京当初は山関係の広告代理店に勤めていたが、次第に雑誌にイラストを提供する仕事が増えていく。アウトドア雑誌での連載スタートを機に会社を辞め、山をテーマに、イラストと紀行文を寄稿することが生業となっていった。けれど、取材で山へと訪れても、いわゆる弾丸ツアーで帰って来なくてはならない。深夜バスで到着し、登ってすぐに降りてバスで戻り、深夜まで原稿を書く生活に疑問を覚え始める。外に出てもアスファルトばかりの東京が、「ああ、ちょっとしんどいな」と、岐阜へと帰ることに。自分の“山”を取り戻すための帰郷だった。
実家のすぐ近く、半分雑木林になっていた休耕田を借りた。借地なのでコンクリートを打つことも砂利をまくことも禁止。そのために、軽やかな小屋を建てることにした。谷から石を拾ってきて土台とし、安い板材を入手して、ほとんど機械を使うことなく小屋を建てた。父親からは知恵とほんの少しの労力を借りたが、ひとりですべての工程を為すことをルールとした。
Create with your own hands what you need but do not have. Being influenced by his father who worked as a carpenter, Naruse-san embodied his own ideology and set off to live life by his own hands. His illustration work falls under the same category. Being raised under the influence of artists such as Hoshino Michio and Sekino Yoshiharu, known for his “Great Journey”, who express their relationships with nature, is one of the reasons Naruse-san started to draw. “In order to pursue illustration I must go to Tokyo.” This is the idea that Naruse-san took to heart after graduating from university in Yamanashi-prefecture. Upon his move to the capital, he found work at an advertising agency specializing in mountain themes but gradually found more and more illustration work for magazines. He took an opportunity from an outdoor magazine, quit his job at the company, and started illustrating and writing full time. However, in order to gather the necessary data for his artwork, his work trips to the mountain were nothing more than single day trips that often involved a night bus to the location, a quick climb, and return to the city where he would write and draw into the early morning. Naruse-san started having doubts about this new lifestyle. The asphalt jungle of Tokyo became “tiresome”and he decided to move back to Gifu. This was a homecoming that would allow him to take back the mountain.
Naruse-san rented out a piece of idle farmland that was half overgrown with trees. Because it was rented land, it was strictly forbidden to lay concrete or gravel and thus he started to construct a less than serious cabin on the ground as is. Hauling stones from the valley he created the foundation and with using minimal machinery, scraps of wood, and other inexpensive materials, he was able to complete the cabin. Other than the knowledge that was passed down from his father, and other than the small amount of manual labor help that he received from his father, he made it a personal quest to complete the entire process on his own and by the limits of his own hand.
