Japan passport holders do not need a visa to visit Singapore for stays of up to 30 days.
Japan's Ministry of Foreign Affairs says a visa is not needed for tourist or business trips of up to 3 months; at entry a stamp permitting a stay of 14 to 30 days is given, so always check the number of days permitted.
“観光、商用を目的とした旅行で、かつ、滞在期間が3か月以内の場合、査証は免除されます。入国時には、14～30日間の滞在許可印が押されますので、必ず許可された滞在日数を確認してください。”

Japan citizens can enter Singapore without a visa and stay for up to 30 days. You only need a valid Japan passport at the border; immigration officers may still ask for a return or onward ticket, proof of accommodation and enough money for your stay. The 30-day limit usually counts calendar days from your arrival, so book your return flight inside that window.
Whatever your visa status, Singapore applies the same entry conditions to every traveller:
Singapore lets 163 passports in without a visa and requires an embassy visa from 35. Japan citizens are treated the same way as Bahrain, Bhutan, Brunei, Cambodia and China. Overall the Japan passport ranks #34 in the world with 116 visa-free destinations.
Planning a longer trip in Asia? With a Japan passport you can also visit 20 countries in the region without a visa, including Brunei, China, Hong Kong, Iran, Kyrgyzstan, South Korea, Kazakhstan and Laos.
In the other direction, Singapore citizens can visit Japan visa-free for up to 90 days.
