n8n, Claude Code, AI Agent: Where Search Moved in Korea and Japan

Short Answer

Between 2025 and 2026, interest in work automation across South Korea and Japan concentrated on one tool before shifting to the next. Peaks occurred in sequence: Cursor (April 2025), n8n (June 2025 in Japan, December 2025 in South Korea), and Claude Code (March-April 2026). Preferred tool names rotated roughly every year, while interest in the term 'AI Agent' grew steadily.

Peaks and Current Status

Searches for tool names (Cursor, n8n, Claude Code) declined significantly after peaking. In contrast, terms describing workflow concepts (vibe coding, AI Agent) remain at or above 60% of their peak levels.

From Cursor to n8n, from n8n to Claude Code

Peak searches for n8n differed by six months between the two countries. Japan peaked in June 2025 at 60,500 searches and maintained similar levels through October. South Korea peaked in December 2025 with 71,260 searches. Search volume over the latest 6 months fell 42.4% in South Korea and 49.8% in Japan compared to the prior 6 months.

Claude Code peaked at nearly the same time in both countries: March 2026 in Japan (823,000 searches), while South Korea peaked in March for English 'claude code' and in April for Korean '클로드 코드'. In some cases like n8n, Japan leads; in others like Claude Code, both markets move together. Using Japanese search trends as a leading indicator for South Korea requires examining each tool individually.

More Users Searching in Korean

In South Korea, search trends for Claude Code diverged depending on whether users searched in Korean or English.

While English searches held steady, Korean searches increased by 77%, shifting the share of Korean queries from just over half to two-thirds. This may signal that interest expanded beyond developers who search using the English product name to general office workers searching in Korean. Because search volume alone cannot verify an individual's occupation, this remains a working hypothesis.

'AI Agent' Outlasts Specific Tools

In both markets, search volumes over the last 6 months exceeded those of the prior 6 months. South Korea peaked in July 2026 at 39,990 searches, while Japan held at 60,500 searches from March through June 2026. Even as interest in specific tools cooled, interest in the term 'AI Agent' continued to grow.

Key Takeaways from This Data

• AX leaders: The most searched tools during this period rotated roughly every year. Building training and adoption plans around tool names means redesigning them the following year. Planning around task definitions, such as which jobs to assign to agents, creates more durable programs.
• IT administrators: Growth in Korean searches for '클로드 코드' suggests that users outside development organizations may be adopting the tool. Usage policies and account governance rules now need to cover non-developer teams.
• B2B marketers: Conceptual terms like 'vibe coding' and 'AI Agent' sustain search volume longer than specific tool names. For evergreen content, broad terminology offers greater longevity.

Methodology

• Tool: ListeningMind keyword_info, South Korea and Japan, October 2024 to September 2026, retrieved October 21, 2026.
• South Korea reflects combined monthly search volumes from Naver and Google; Japan reflects Google monthly search volume. Rather than comparing absolute search volumes between the two countries, comparisons are based on percentages relative to each keyword's peak.
• The index relative to peak sets each keyword's highest month to 100.
• In Japan, the query 'cursor' was excluded from the table because it overlaps with general terms such as mouse cursor. The Japanese term 'バイブコーディング' showed no recorded data.
