Simultaneous bilingual disclosure

Bilingual disclosure:
On time, every time.

Kaiji Labs handles the translation and review of regulatory disclosures — earnings summaries, securities reports, timely disclosure — ahead of filing day, so JA and EN release together. Built for TSE-listed companies and the funds that read them.

Today's disclosures, tomorrow's assets.

The challenge

English disclosure is no longer optional.

The TSE expects English disclosure to be released at the same time as the Japanese original. For IR teams, that turns every earnings day into a translation deadline.

  • Volume and speed
    Quarterly tanshin, timely disclosure, yuho, and presentation materials all need English versions — on tight, simultaneous deadlines.
  • Quality stakes
    Mistranslated financial terminology or inconsistent language erodes investor confidence in every release that follows.
  • Resource drain
    IR teams spend hours reviewing translations line by line — time that should be spent with investors.

95% of TSE firms lack full same-day English disclosure.

  • Delayed 9%
  • Summary only 1%
  • On time 5%

Why current solutions fall short

Three options, none built for IR.

Free AI tools
  • No financial vocabulary, no memory of past disclosures
  • Inconsistent terminology between documents
  • Every output needs full review by IR staff
No real reduction in workload
Traditional IR translation firms
  • Manual workflows from start to finish
  • High cost and slow delivery
  • Limited capacity in peak reporting weeks
Expensive expertise spent on boilerplate
Large translation agencies
  • Translation memories and some AI in the workflow
  • Automation stops at the sentence level
  • Human hours still spent on DTP and templates
Faster words, same slow documents
