| 2026-01-13 | Exec interviewJapanese-onlyMujin CEO Issei Takino: 'Customers won't buy on technology alone' ロボット制御ソフトのMujin滝野CEO「技術だけで買ってくれるほど甘くない」 Takino explains the split of the Dec 2025 ¥36.4B raise: ¥20.9B equity for R&D and overseas growth, ¥15.5B in loans for working capital. The loans are needed because projects that were ¥200–300M five years ago are now often over ¥1B, some above ¥5B, and customer payments lag delivery. This is a rare look at Mujin's deal sizes and cash-cycle pressure. Source: Nikkei Business |

He adds that software updates lift palletising throughput 30–40% a year on unchanged robots (for example 400 to 800 cases/hour). Japanese trade press is the only place these growth figures appear.

This frames Mujin's shift from integration projects to a product business. Source: Toyo Keizai (paywalled; public part only) |
Overview
Mujin makes intelligent robot controllers and MujinOS, a digital-twin platform that runs robots, AGVs and storage systems across a factory or warehouse without hand-teaching each motion. Customers are manufacturers and logistics operators such as Sango, TEPCO Logistics and Nippon Unyu; it sells products like palletisers and AGVs plus integration and consulting. More than 1,500 MujinAGVs run in Japanese plants. Its December 2025 Series D first close (¥20.9B equity plus ¥15.5B debt, co-led by NTT and the Qatar Investment Authority) was Japan's largest startup raise of 2025 and lifted its valuation above ¥150B.
