A vintage, artisan-made Japanese bonsai pot（日本製盆栽鉢）crafted by Izumi-ya Matsushita Masuo, known professionally as SENGO / Zenigo (仙吾 / 泉吾)—a respected Tokoname potter active during the mid-20th century.
This unglazed rectangular pot（無釉長方鉢）displays elegant Tokoname lines with gently flared walls（反り外壁）and a well-defined rim / lip（見込み縁）that give the form a refined upward movement. The cut, stepped feet（切り高台・雲脚）show classic hand-finishing associated with Sengo’s workshop.
The pot is crafted from warm Tokoname clay with natural grog inclusions（砂粒入り土）, providing both texture and improved breathability. Over time, it has developed a beautiful aged patina（経年の風合い）that enhances its depth and character—qualities sought after by collectors.
A lower basal band（下面帯・下部胴帯）wraps the pot just above the feet, adding subtle structural definition without interrupting the clean plane of the walls.
On the underside, the pot features the impressed Izumi-ya / Sengo seal（泉屋・仙吾印）executed in tensho-style script（篆書体）, along with dual drainage holes（排水穴）and additional wiring holes（針金穴）for secure bonsai mounting.
