Japanese job-hunting web-test bank with 699 practice questions across 8 banks, a 663-company test directory and an AI photo solver, in three languages.
A cheap first look at SPI, Tamatebako and CAB style questions and at which employers recorded which test, across eleven exam tracks. It cannot be bought yet, and its operator and content licence are not stated, so treat it as a free-sample tool for now.
A company directory that pairs employer names with the aptitude test types recorded for each.
Lock-in is low: the value sits in the question records and the company directory, which a rival with better content rights could match, while the photo solver is a generic feature.
Main trade-off
Payment is not live and the operator and content licence are not stated.

The paid One Year Pass is a single payment of 2,000 yen that unlocks every bank for 365 days, and it does not renew by itself. Stripe handles checkout, but the pricing page says payment integration is still being prepared, so on 11 November 2026 there was no way to buy it.
Yes, within limits. Guests can read the first 2 questions of each practice set and signed-in users the first 5, and the answer search has its own free sample list. The pricing page instead promises 3 fixed free questions in every bank, so the exact allowance is stated two ways.
Its company directory shows, for each employer, the test types recorded, plus stage and year where known. Tamatebako is recorded for 164 companies and SPI for 293. The site warns that tests vary by year, role and stage, so check the employer's own invitation.
It solves up to 3 questions at once from photos. Registered free users get 2 trials, and the paid pass raises the total to 5 trials, so it is a small allowance rather than an unlimited solver. The site labels it AI but does not say which model runs it.
Sample results carry labels such as "Reviewed correction" and "Checked against the stated rule". On the free items read that day, the answer-basis field under each result was empty, so the reasoning was not visible.
WebTestNavi is a preparation site for the aptitude tests that Japanese employers use in graduate recruiting, such as SPI, Tamatebako (玉手箱), GAB and CAB. Its menus come in Japanese, English and Chinese. The operator is not named anywhere Hokai could read: the footer says only "© 2026 WebTestNavi".
On 11 November 2026 the practice page counted 186 Tamatebako questions, 105 for SPI, 199 for CAB and smaller sets for the other five banks. The samples Hokai read were in Japanese, so the Chinese and English interfaces translate the menus rather than the questions themselves. That makes it a fit for students applying in Japan who read Japanese, and a weaker one for readers who need the questions explained in English.
Two limits shape the decision. Checkout is not open yet, so the paid pass cannot be bought. And for ordinary school maths the photo solver is not the point, because Photomath, a camera-based solver from Google with free step-by-step answers in 32 languages according to its Hokai record, and Gauth, a homework solver with a free plan limited in use, are built for it. Both sit on the same shelf as WebTestNavi, AI grading tools.
Product facts on this page (pricing, plans, integrations, compliance) are read from WebTestNavi's own pages and documentation. The verdict is Hokai's reading of them, not the vendor's claim.
