Gotanda Hitozumajo — Three Different Discounts Land on One Identical Price List, and Minutes 61 Through 100 Cost ¥100 Each
Gotanda Hitozumajo publishes a new-customer discount, a weekly Friday event and an always-on hotel-first discount. At eighty minutes and up, all three produce the exact same six prices. Meanwhile the marginal minute between sixty and a hundred costs ¥100, which makes the eighty-minute course ¥1,000 cheaper than the sixty.
