Careful, it varies a lot between brokers: at Vantage (Nikkei225) 1 lot is worth ¥1 per point and the minimum lot is 1; at Axi (JPN225) 1 lot is worth ¥100 per point and the minimum is 0.1. The calculator starts from Vantage: if you use Axi, enter 100 as the contract size and 0.1 as the lot step.

JP225: 1 point = 1 in price. Values in JPY, the currency it is quoted in; the calculator converts them to your account currency. With a contract size of 1 per lot, the most common one; check your broker’s.
Contract size and minimum lot checked on against the Vantage and Axi specifications.
A $10,000 account, 1% risk ($100) and a stop 150 points away. Each point is worth 1.00 JPY per lot, so the stop costs 150.00 JPY per lot: 100 ÷ 150.00 = 0.00 lots.
On JP225, 1 point is a move of 1 in the price. With 1 lot (contract size 1) it is worth ¥1; with 0.10 lots, ¥0.10, and with 0.01 lots, ¥0.01. As JP225 is quoted in JPY, the calculator converts it to your account currency at the ECB exchange rate.
With a 150-point stop, each lot loses ¥150. To risk ¥15,000: 15,000 ÷ 150.00 = 100.0000 lots, which rounded down to the 1.00 step is 100.00 lots.
It depends on the broker, like the contract size. The calculator starts from a 1.00 minimum lot and a contract of 1 per lot; you can change both in “Broker settings”. In MT4/MT5, right-click the symbol → Specification.
For retail clients in the EU, ESMA caps JP225 at 1:20. At a price of 44,000, 1 lot controls ¥44,000 and needs about ¥2,200 of margin.
