Navigate Tokyo's stations like a local.
Ground-truth navigation for Tokyo's busiest train stations, built for English-speaking travelers. Every route is verified on foot — real step counts, exact elevator and escalator locations, and the right gates and exits.
Your graded collection, tracked and valued.
A portfolio tracker for PSA and CGC graded cards and comics. Log your slabs by cert number, follow real eBay price history for the exact grade you hold, and see your collection's total value at a glance. Currently under review in the App Store.
The archive for Japanese Domestic Market classics.
A reference database for JDM legends — specs, production history, and rarity for the cars US enthusiasts actually care about. Built as an archive, not an auction feed.
Find the right artist, in the right neighborhood, in English.
A curated guide to Tokyo tattoo artists and studios for English-speaking clients. Browse by style, neighborhood, and booking openness, with straight answers about language support, pricing, and etiquette.
Accounts, live market pulls, and saved notes.
A future tier for the Outlook — not available for purchase yet. When it lands, accounts will unlock live Dow / S&P 500 / Nasdaq-100 pulls, personal market notes, and member-only deep dives. Pricing and perks are still being shaped; nothing is billable today.
USD / JPY purchasing power over time.
A free companion to the compound calculator. Convert across currencies with historical exchange rates and adjust for each country's inflation, so you can compare what a yen or dollar actually bought, then and now.
How the machinery actually works.
An ongoing series of op-eds explaining the mechanics under the headlines — yield curves, central bank balance sheets, the carry trade, and what changes when each one moves. Mechanisms over predictions.
Launch windows reflect current planning and can shift. Nothing here is a commitment; we publish what ships when it ships.
Occasional op-eds and launch notes — no noise, no tracking.
Kodama Labs — Economic Outlook & tools. The Outlook publishes general economic commentary and the tools provide educational models. None of it is personalized investment advice, a recommendation to buy or sell any security, or a substitute for guidance from a licensed professional who knows your full situation.
