Start Your Free Accurate Translation“I've never seen a free Indonesian to Japanese machine translator this good. Legal and contract terms are handled with awareness of UU Perlindungan Data Pribadi Indonesia and Japanese privacy law—with honorifics and keigo rendered properly, unlike most generic systems.”Novia Kusuma, M.Hum., Himpunan Penerjemah Indonesia (HPI)

Guarantee Perfect Accuracy with a Free Custom Dictionary
Custom word lists are essential for full accuracy. You can ‘lock in’ Japanese translations for names, brands, and industry terms so they're never mistranslated. This is especially useful for Indonesia–Japan business and technical projects.
Brand Integrity
Your company or product names (e.g., Garuda Indonesia, Tokopedia) always stay correct—never turned into a Japanese generic noun.
Technical and Manufacturing Terms
Ensure ‘panel surya’ always becomes ‘太陽光パネル’, not a literal or awkward phrase. Applies to automotive, electronics, and factory documents.
Regulatory Terminology
Align translations for ‘NPWP’ as ‘納税者番号’ (Tax ID), or ‘SIUP’ as ‘営業許可証’ (Business License), matching what Japanese authorities expect.
Consistent Legal Clauses
Use set language for phrases like ‘dengan ini disetujui’ to standard Japanese legal equivalents, keeping contracts clear for both sides.
Accurate Translations for Every Profession
Don’t risk costly mistranslations on Indonesian-Japanese documents. Our system is tuned for fields where subtle nuance or regulation is critical.
Legal & Corporate
Scenario:
Translating a PT (Perseroan Terbatas) merger agreement from Indonesia for a Japanese firm with offices in Marunouchi, Tokyo.
Challenge:
A mistranslation of ‘tanggung jawab terbatas’ (limited liability) or of references to Indonesian law can cause compliance issues under the Japanese Companies Act or Civil Code.
Solution:
Our AI is trained on Indonesian and Japanese corporate legal corpora, ensuring terms match what legal counsel in either country would expect.
Finance & Manufacturing
Scenario:
Analyzing an Indonesian financial report for a manufacturing joint venture in Osaka.
Challenge:
Japanese Yens and Indonesian Rupiahs use very different formats. Terms like ‘arus kas’ (cash flow) or ‘penyusutan’ (depreciation) are commonly mistranslated, which can distort analysis.
Solution:
AI normalizes number formats and accounting vocab—using the standard accounting terms accepted by keiri-bu (経理部) in Japan or a finance team in Jakarta.
Technical & Engineering
Scenario:
Localizing a user manual for palm oil processing machines exported from Medan to Chiba.
Challenge:
Literal Indonesian-to-Japanese often mistranslates technical cautions (e.g. ‘Matikan mesin sebelum membersihkan’), risking safety compliance.
Solution:
Our AI references both Japanese operation manual standards (e.g., JIS) and Indonesian best practice, always using proper warning phrasing.
