Opinions forged beside the ledgers they examine

Blue Coast Audit Cabinet conducts statutory financial statement audits and related assurance work for manufacturers, trading houses, and professional groups that file in Japan. Fieldwork stays close to inventory floors, bank confirmations, and board calendars — not to abstract product roadmaps.

Statutory financial statement audit

For companies that must present an independent auditor’s report with Japanese GAAP or IFRS statements. We plan materiality, test balances, observe inventory where stock is material, and deliver a signed opinion aligned to your board meeting date.

Engagements typically run eight to fourteen weeks from planning to signature, with fieldwork on site and file review at our cabinet.

What finance leads say after fieldwork

“They insisted on recounting two slow-moving aisles we had hoped to skip. The adjustment stung, but the bank accepted the pack without a follow-up query.”
Keiko M., CFO · precision components, Yamagata
“The English management letter arrived a day later than promised after a snow delay at the plant — they flagged the delay themselves before we asked.”
Lars H., Group controller · EU parent with JP subsidiary
