Lewis Watson MEng (Cantab)

Lewis read Chemical Engineering at the University of Cambridge and has tutored full time since 2015. He teaches both halves of the Digital SAT himself: the Math with an engineer’s command of the quantitative section, Reading & Writing with the ear for language the verbal half rewards.

Much of the early work was residential, living with families in Dubai and Saudi Arabia and teaching through term time and exam season, before the practice moved mostly online. More about Lewis →

Why students in Tokyo come to one-to-one lessons

Tokyo's SAT students are a more varied group than the international-school list suggests. Alongside ASIJ, the British School in Tokyo, Nishimachi, Seisen, St. Mary's and K. International, there is a large cohort of returnees, kikokushijo who spent years abroad and are now at Japanese schools, and a growing number of Japanese students at ordinary high schools applying to the English-taught programmes at Waseda, Keio, Sophia and others, several of which use the SAT in admissions.

What those students share is that Tokyo has surprisingly little SAT preparation for a city its size, and what exists is either juku-style drilling or a group course on a fixed timetable. A returnee whose English is fluent but whose Math vocabulary is entirely Japanese, and a Japanese-school student whose Math is superb but who has never read a fast multiple-choice passage in English, need opposite things, and a course cannot give both.

One-to-one lessons are built around the student's actual profile, and scheduled in a Tokyo evening, after school or after club activities, rather than at whichever hour a centre has free.

Lesson times in Tokyo

Tokyo is on Japan Standard Time (UTC+9). These are the slots students here book most often, with the corresponding UK time in both halves of the year, so you can see the lesson falls inside a normal working day at the tutor's end, which is what keeps a weekly slot stable through a whole term.

Lesson time where you are UK time, Apr–Oct UK time, Oct–Mar
5.00pm9am UK8am UK
6.00pm10am UK9am UK
7.00pm11am UK10am UK
8.00pm12pm UK11am UK
9.00pm1pm UK12pm UK

The UK moves between GMT and British Summer Time in late March and late October; Japan does not change clocks, so the UK-side time shifts by an hour twice a year while your lesson time stays put.

International schools in Tokyo

Many students preparing for the SAT in Tokyo are at one of its international schools. Among the best known are The American School in Japan, The British School in Tokyo, St. Mary’s International School and Nishimachi International School.

What lessons cost from Tokyo

One rate for every student: £135 an hour, roughly ¥29,500 at mid-2026 exchange rates. Lessons are billed in pounds sterling on the day each one takes place, so the local figure moves with the exchange rate. The intro call and the trial lesson are free. Everything the rate covers is on the fee sheet.

Who is the best online SAT tutor in Tokyo?

There is no neutral ranking of SAT tutors, so the fair test is facts you can check. Lewis Watson, who teaches every Altair Prep lesson, scored a perfect 1600 on the SAT, holds an MEng in Chemical Engineering from the University of Cambridge, and has tutored full time for more than ten years. He teaches both sections of the Digital SAT, Math and Reading and Writing, himself: one to one, online, at a fixed weekly time in Japan time (UTC+9). Ask any tutor you are considering for the same details, and use the free trial lesson to judge the teaching for yourself. There is more about Lewis on his own page.

Common questions from Tokyo

Can I find an online SAT tutor in Tokyo?

Yes. Altair Prep teaches one-to-one Digital SAT lessons online to students in Tokyo and Yokohama, live over a shared interactive whiteboard, at a fixed weekly time in Japan's own evening. Lewis Watson, a Cambridge-educated native English speaker with a perfect 1600, teaches every lesson himself and covers both the Math and the Reading and Writing halves, with homework marked between lessons.

What time are SAT lessons for students in Japan?

Japan is on UTC+9, eight hours ahead of the UK in summer and nine in winter, so a 7.00pm lesson in Tokyo is 11.00am or 10.00am in London. Altair Prep holds evening slots in Japanese time, after school or after club activities, as a standing weekly appointment through the term, and weekend lessons are available as well.

Do Japanese universities accept the SAT?

Some English-taught programmes do. Programmes at Waseda, Keio, Sophia and other universities accept the SAT as part of admissions to their international or English-medium degrees, and the required scores and accepted alternatives are set programme by programme and change from year to year, so check the specific one. Altair Prep plans around that programme's deadline and score range exactly as it would for a US application.

My child is a returnee whose English is fluent. Why is the Math score low?

Usually because the mathematics was learned in Japanese and the SAT asks about it in English. A kikokushijo student often knows the content well and loses marks to vocabulary and to word problems, not to the maths itself. Altair Prep's first lessons establish exactly that, and then teach the language of the Math section alongside timed practice rather than re-teaching content the student already has.
